Abstract:
Electric vehicles (EVs) are one promising technology for an improved sustainable transportation sector, particularly when they are charged with electricity from renewable energy sources. However, the EV user behaviour uncertainties as well as the fluctuating generation of renewable energy sources make the interaction between these technologies challenging. In this work, a new approach to coordinate the charging process of multiple EVs parked at workplace charging station (WCS) equipped with Photovoltaic panels (PV) is proposed. Considering the PV incremental cost and the day-ahead electricity price (DAEP), an optimal framework is introduced to maximize the WCS owner profit while compensating the EV users for discharging their EVs’ battery. The EV user behaviour uncertainties are modeled by probability distribution functions, and the PV generation is forecasted by the backpropagation neural network model (BPNN). The optimization problem is solved by mixed-integer linear programming (MILP) while the Monte Carlo sampling methods have been applied to handle the EV user behaviour uncertainties. The results show that the proposed method increases the WCS owner profit and the EV user compensation by 54% and 50.7%, respectively, compared to uncoordinated charging. Moreover, the estimated WCS owner profit and the EV user compensation generated by coordinated charging are 1.72% and 1.35%, respectively, higher than the profits based on real user behaviour data.

Abstract:
In this paper we estimate the determinants of cost and profit efficiency of Islamic banks using the stochastic frontier approach SFA. We use 62 Islamic banks in sixteen countries of the MENA and South-East Asia regions during the period 2004-2010. We compare the efficiency between Islamic banks during the subprime crisis phases. Moreover, we examine the variables specific to the banks which can explain the sources of inefficiency and those let us decline the scores of cost and profit efficiency on a specific number of variables (total assets, capital adequacy, profitability, credit risk, operational costs). Results reveal that, Islamic banks in our study are more efficient in the generation of the profits rather than in the control of the costs. Thus, only the total assets and the operational costs represent the determinants of cost efficiency of the Islamic banks. Finally, for the profit efficiency our results indicate that the Islamic banks with high equities and high ratio of profitability are efficient in terms of profit.

Abstract:
The increased use of electricity in modern power systems is demanding the use of non-conventional energy sources to a large extent due to the limited stock of conventional energy sources. The present paper focuses on Gravitational Search Algorithm (GSA)-based optimal allocation and sizing of solar and wind power generating units in transmission systems. The performance of the optimization method has been tested on the IEEE-14 bus test system in terms of total generation cost minimization of conventional generating units, transmission line loss reduction, revenue earned from optimal generation of solar and wind power, and profit of non-conventional generating unit owners. The comparative study on the optimal installation of standalone solar, standalone wind, and a combined solar-wind system within the existing conventional transmission system has also been conducted to achieve better results.

Abstract:
Tax revenue is a crucial financial resource for governments worldwide. Developed nations often secure ample tax revenue through robust industrial performance. In contrast, developing economies struggle with various challenges that hinder tax revenue from sources such as income, profit, and capital gains, largely due to high unemployment and inadequate industrialization. This study employed an ex-post facto research design and analyzed panel data from 38 countries over 21 years (2001–2021), sourced from the World Bank Group Database. The System Generalized Method of Moments (SGMM) analysis revealed that industrial performance significantly impacts tax revenue from income, profit, and capital gains in sub-Saharan African countries. The study concluded that advancing industrialization in sub-Saharan Africa is essential for maximizing tax revenue from these sources. It is recommended that governments in the region focus on accelerating industrial growth as a strategy to achieve sustainable tax revenue generation.

Abstract:
Daily load demand for industrial, residential and commercial sectors are changing day by day. Also, inclusion of e-mobility has totally effected the operations of realistic power sector. Hence, to meet this time varying load demand with minimum production cost is very challenging. The proposed research work focuses on the mathematical formulation of profit based unit commitment problem of realistic power system considering the impact of battery electric vehicles, hybrid electric vehicles and plug in electric vehicles and its solution using Intensify Harris Hawks Optimizer (IHHO). The coordination of plants with each other is named as Unit commitment of plants in which the most economical patterns of the generating station is taken so as to gain low production cost with higher reliability. But with the increase in industrialization has affected the environment badly so to maintain the balance between the generation and environment a new thinking of generating low cost power with high reliability by causing less harm to environment i.e. less emission of flue gases is adopted by considering renewable energy sources.

Abstract:
The unit commitment (UC) problem aims to reduce the power generation costs of power generation units in the traditional power system structure. However, under the current arrangement, the problem of cutting the cost of producing electricity has turned into an opportunity to boost power generation units’ profits. Emission concerns are now given considerable weight when talking about the performance planning of power generation units, in addition to economic objectives. Because emissions are viewed as a limitation rather than an objective function in the majority of recent research that has been published in the literature, this paper solves the multi-objective profit-based unit commitment (PBUC) problem while taking into account energy storage systems (ESSs) and renewable energy systems (RESs) in the presence of uncertainty sources, such as demand and energy prices, in order to minimize generated emissions and maximize profits by power generation units in the fiercely competitive energy market. Owing to the intricacy of the optimization problem, a novel mutation-based modified version of the shuffled frog leaping algorithm (SFLA) is suggested as a way to get around the PBUC problem’s difficulty. A 10-unit test system is used for the simulation, which is run for a whole day to demonstrate the effectiveness of the suggested approach. The proposed algorithm’s output is compared with the best-known approaches from various references. The simulated results generated by the suggested algorithms and the previously reported algorithms to solve the PBUC problem show that the proposed method is better than other evolutionary methods utilized in this study and prior investigations. For example, the overall profit from the suggested MSFLA is around 4% and 5.5% higher than that from other algorithms like the ICA and Muller methods in the presence and absence of reserve allocation, respectively. Furthermore, the MSFLA emissions value is approximately 2% and 8% lower than the optimum emissions values obtained using the PSO and ICA approaches, respectively.

Abstract:
The integration of renewable energy generation affects the operating characteristics of a power system, such as electric losses, voltage profile, generation cost, system stability, and reliability of the system. The installation of renewable energy generation units in non-optimal locations may increase system losses, costs, voltage fluctuations, etc. The main hurdle in integrating renewable energy generation units with an existing electrical grid is the uncertainty of renewable sources. This paper presents the impact of wind farm integration on the system economy in a wind-integrated deregulated power market. The importance of deregulation in terms of the system generation cost, bus voltage profile, and locational marginal pricing (LMP) are also studied in this work. LMP is the main parameter responsible for handling the system economy (i.e., profit of generating units and profit of customers). Considering the variable nature of wind flow, three different real-time wind speed datasets are used to validate this work. Bus sensitivity factor (BSF) is considered for equating the optimal position of the wind farm in the integrated system. Five different optimization techniques, i.e., sequential quadratic programming (SQP), artificial bee colony (ABC) algorithms, particle swarm optimization (PSO), ant colony optimization (ACO) algorithm, and slime mold algorithm (SMA), are introduced to solve the optimal power flow problem. The SMA and ACO are used for the first time in this type of economic assessment (i.e., impact valuation of LMP) in a deregulated power system, which is the novelty of this work. The entire work is performed in a modified IEEE 30 bus test system.

Abstract:
The current scenario of micro and mini distributed generation (micro and mini DG) in Brazil has been developing steadily and the power injection through the Distributed Generation (DG) regarding the development of small-scale sources of electricity production represents an alternative to the Brazilian energy grid. Considering the amended Normative Resolution No. 482/2012 (REN 482/2012) of the Brazilian National Agency of Electric Energy (ANEEL), which regulates the connection and the compensation of power systems in micro and mini DG through the REN 687/2015 expected for March 2016, it can be observed an incentive to the complementarity between the sources of DG and the integration of available resources. The insertion of micro and mini GD to the electrical distribution system presents numerous benefits. On the other hand, the penetration of these sources in an integrated manner will render this a complex system from operation and planning perspective, mainly related to operational characteristics of the network, such as voltage levels, active and reactive power loading, conductors loading, bidirectional power flow, electrical losses, among others. The aim of this study is to develop generation profiles of a photovoltaic solar system, producing a generic curve of hourly generation over a day. It is important for the power distribution companies to determine the degree of penetration at different times of a day so as to analyze operational impact on the feeders with the implementation of DG, since the companies regulate the number of Distributed Generations (DGs), but not the degree of penetration of the those at different times. Moreover, the complementarity will be carried out by overlapping the curves to integrate the ones from the photovoltaic systems with those from the biogas manure generation systems. The operational impact on the distribution network due to the insertion of these DG sources will be analysed. The aspects considered are voltage level, active and reactive power loading, conductors loading and electrical losses.<br>O atual cenário da micro e minigeração distribuída (micro e miniGD) no Brasil vem em uma crescente, ou seja, a injeção de potência através da Geração Distribuída (GD) com o desenvolvimento de fontes de pequena escala de produção de energia elétrica, se apresenta como uma alternativa na matriz energética brasileira. Com as alterações da Resolução Normativa nº 482/2012 (REN 482/2012) da Agência Nacional de Energia Elétrica (ANEEL), que regra o sistema de conexão e compensação de energia elétrica das micro e miniGD através da REN 687/2015, que entrou em vigor em março de 2016, instiga, cada vez mais, a complementariedade de fontes de geração distribuída com a integração de recursos disponíveis. Incontáveis são os benefícios que se apontam a partir da inserção das micro e miniGD ao sistema elétrico de distribuição. Em compensação, a penetração dessas fontes de forma integrada tornará esse sistema complexo sob a ótica da operação e planejamento, principalmente referente às características operacionais da rede como níveis de tensão, geração de potência ativa e reativa, carregamento dos condutores, fluxo de potência bidirecional, perdas elétricas, entre outros. Este trabalho tem por objetivos o desenvolvimento de perfis de geração de um sistema solar fotovoltaico, na modelagem de uma curva genérica de geração horária ao longo de um dia, tendo em vista que para as concessionárias é importante saber o grau de penetração em cada horário para se analisar os impactos operacionais que podem ser provocados nos alimentadores com a inclusão da GD, já que elas possuem o controle do número de Gerações distribuídas, mas não, o grau de penetração das mesmas em cada horário. Ainda, será realizada a complementariedade através da sobreposição de curvas na integração de sistemas fotovoltaicos com sistemas de geração a partir de biogás de dejetos suínos. Ao realizar a integração desses recursos de geração serão analisados os comportamentos operacionais (nível de tensão, carregamento de potência ativa e reativa, carregamento de condutores e perdas elétricas) causados a rede de distribuição devido à inserção dessas fontes de GD de forma conjunta.

Abstract:
The growing share of installed wind power in the Swedish electricity system has caused concerns whether the available regulating power will be sufficient. Several studies have examined the need of regulating power using both statistical and modelling approaches. However, there is a risk that some aspects of the short-term regulation of hydropower might have been missed. By using one of Vattenfall’s hydropower planning tools, the short-term operation of The Lule River has been simulated with an increasing penetration of wind power. The tool includes detailed models of reservoirs, generating units including efficiency curves and start/stop costs. By introducing a day-by-day simulation with a seven-day window price forecast, updated with a new wind forecast for each iteration, a 21-days scenario has been simulated. Transmission limits are disregarded and the thermal production is reduced with the average wind production. To quantify and compare the regulation capacity, the regulation factor is introduced. It reflects the ability to utilise high-price hours and considering that the need of regulating power for the short-term perspective is reflected in the price it will also reflect the regulation capacity. It is shown that the regulating factor is correlated to the discharge factor,whichis the relation between the maximum discharge to the average statistical discharge for a plant. A high discharge factor provides the flexibility to utilise the fluctuations in price. The discharge factor is adapted to the plants placement in the reach, accounting for both reservoirs located upstream and downstream, especially for The Lule River which has been designed to regulate for the fluctuations in the load. The flexibility required by the rest of the Nordic rivers is quantified for future studies. It is concluded that The Lule River is able to meet some of the fluctuations of wind power production due to the overcapacity ininstalled power. The production can, at the expense of decreased efficiency of the generating units, alter the production to suit a more fluctuating price.It is important to emphasise that The Lule River alone cannot balance a large penetration of wind power. To fully take into account the effects of a large penetration of wind power the study must be expanded to include more scenarios. The study should include different types of hydrological prerequisites and the seasonal variations in power production as well as additional rivers.

Abstract:
Experiments and numerical investigations on trapped electron plasmas and traveling electron bunches are discussed. A Thomson backscattering diagnostics set up was installed in the ELTRAP (Electron TRAP) device, a Penning-Malmberg trap operating at the Department of Physics of the University of Milano since 2001. Here, an infrared (IR) laser pulse collides with nanosecond electron bunches with an energy of 1-20 keV traveling through a longitudinal magnetic field in a dynamical regime where space-charge effects play a significant role. The backscattered radiation is optically filtered and detected by means of a photomultiplier tube. The minimum sensitivity of the backscattering diagnostics has been estimated for the present set-up configuration. Constraints on the number of photons and thus on the information one can obtain with the Thomson backscattering technique are determined by the relatively low density of the electron beam as well as by noise issues. Solutions to increase the signal level and to reduce the noise are briefly discussed. The generation of an electron plasma by stochastic heating was realized in ELTRAP under ultra-high vacuum conditions by means of the application of low power RF (1-20 MHz) drives on one of the azimuthally sectored electrodes of the trap. The relevant experimental results are reviewed. The electron heating mechanism has been studied by means of a two-dimensional (2D) particle-in-cell (PIC) code, starting with a very low electron density, and applying RF drives of various amplitudes in the range 1-15 MHz on different electrodes. The axial kinetic energy of the electrons is in general increasing for all considered cases. Of course, higher temperature increments are obtained by increasing the amplitude of the RF excitation. The simulation results indicate in particular that the heating is initially higher close to the cylindrical wall of the device. These results on the electron heating point in the same direction of the experimental findings, where the plasma formation due to the ionization of the residual gas is found to be localized close to the trap wall. The simulations indicate also major heating effects when the RF drive is applied close to one end of the trap. Similar results are obtained for an electron plasma at higher densities, simulating a situation in which the RF is applied to an already formed plasma. With the aim to extend these RF studies to the microwave range, a bench test analysis has been performed of the transmission efficiency of a microwave injection system up to a few GHz. The test was based on the use of a prototype circular waveguide with the same diameter and length of the ELTRAP electrode stack and of a coupled rectangular waveguide with dimensions suitable for a future installation in the device. Electromagnetic PIC simulations have also been performed of the electron heating effect, again both at very low and relatively high electron densities, applying a microwave drive with a frequency of approximately 3 GHz close to the center and close to one end of the trap. Both the bench test of the injection system and the numerical simulations indicate that the new microwave heating system will allow the extension of the previous RF studies to the GHz range. In particular, the electron cyclotron resonance heating of the electrons will be aimed to increasing the electron temperature, and possibly its density as a consequence of a higher ionization rate of the residual gas. The installation of the new RF system will open up the possibility to study, e.g., the interaction between the confined plasma and traveling electron bunches.

Abstract:
Thesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, School of Engineering, System Design and Management Program, 2017.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (page 56).<br>Renewable energy is one of the most important technologies for decarbonizing the economy and fighting climate change. In recent years, wind energy has become cheaper and more widely adopted. However, the variable nature of wind production creates unique challenges that are not faced by conventional thermal technologies. Several studies to date have showed the decrease in economic value of wind energy as penetration increases due to this variable nature. Plus, they also show that high wind penetration favors intermediate energy sources such as natural gas. I claim however, that few of these studies have considered the dynamic behavior and feedbacks of these systems, including investment delays and learning curves. This thesis uses system dynamics models to simulate the long term changes in the electric grid for Texas. The goal is to test two hypothesis: that the economic value of wind energy decreases as penetration increases, and that variable wind production favors natural gas technologies. It does this by calculating how wind energy changes the shape of the net load duration curve for a given region. This affect changes the profitability of different technologies in unique ways, due to their different fix and variable costs. The conclusions of this thesis are consistent with the literature, with the caveat that they are highly dependent on assumptions regarding the learning curve for energy technologies. The economic value of wind decreases, but this effect can be compensated by lower costs, leading to a continuing adaptation. Faster Wind adoption also reduces the profitably of technologies with high fixed costs such as coal and nuclear, and favors intermediate and peaking sources such as natural gas.<br>by Leonardo Mendes Barlach.<br>S.M. in Engineering and Management

Abstract:
This thesis describes an investigation into the performance of different schemes for generating short x-rays pulses via synchrotron radiation emission. A review is given of the methods that have been previously proposed for this task. From this review, three leading schemes are selected for in-depth investigations, each of which explores the boundary of what is presently achievable in accelerator-based light sources. The first scheme generates short x-ray pulses by operating an electron storage ring in a quasi-isochronous state using a ‘low-alpha’ lattice. High and low emittance lattices are developed, studied through simulation and then implemented on the Diamond storage ring. Beam dynamics and bunch length measurements are presented for a variety of machine conditions, and an assessment is made of the minimum practically achievable bunch length for stable user operation. Radiation pulses of 1 ps r.m.s. are demonstrated using this scheme. The second and third schemes investigate performance limits for a linac-based light source through numerical simulations. The first of these generates ultra-short pulses by passing a highly compressed electron bunch through a long undulator to radiate in the ‘single-spike’ regime. A comparison is made with theoretical predictions for the required electron bunch length to operate in this way, which highlights the need for accurate start-to-end simulations. The final scheme generates ultra-short x-ray pulses through laser manipulation of the electron bunches. The modulated electrons pass through a long undulator with tapered gap, such that only the centre of the modulated portion experiences high free-electron laser (FEL) gain. A method to enhance the FEL output from this scheme using a wavelength filter and grating-compressor is investigated. The sensitivity of the two schemes to jitter sources is determined, and it is demonstrated both schemes are capable of generating GW-level, fully coherent sub-fs soft x-ray pulses. Such pulses would open up the development of time-resolved science to new regimes.

Full text
Abstract:
Renewable energy and energy efficiency are increasingly recognised as crucial for creating new economic opportunities and mitigating environmental impacts. Anaerobic digestion (AD) transforms organic materials into a clean, renewable energy source. Co-digestion of various organic wastes and energy crops addresses the disadvantages of single-substrate digestion, increasing production flexibility yet adding process complexity and sensitivity. This study employs a two-pronged approach to optimise biogas production while considering global warming potential: a nonlinear programming (NLP) model for dynamic system economic optimisation with a model predictive control (MPC) strategy for precise temperature regulation within the digester. The NLP model integrates a combined heat and power (CHP) system to leverage dynamic electricity, heat, and gas prices, accounting for physical and economic parameters such as biomethane potential, chemical oxygen demand, and substrate density. A cardinal temperature and pH model ensures accurate depiction of substrate degradation and gas production rates under varying conditions. The MPC scheme, formulated as a system of differential-algebraic equations, offers fine-grained temperature control, capturing real-world complexities like heating/cooling delays, ambient conditions, and multiple feed components with different optimal digestion temperatures. Results demonstrate that this integrated model optimises the interaction between electricity production, biogas generation, and CHP operation for real-time multi-objective optimisation of profit, global warming potential and temperature control. A case study validates the model�s capability for guiding decision-making in biogas facilities, emphasising strategic feedstock management and precise temperature control. Overall, this integrated approach advances the modelling and control of anaerobic co-digestion systems, enhancing both efficiency and profitability in biogas production.

Abstract:
Abstract. This paper presents a comprehensive study on the bidding optimization for hydrogen production from an electrolyzer, focusing on a single day comprising 24 hours. With the rising demand for clean energy sources, the research aims to optimize profitability and efficiency in hydrogen production. The primary objective is to maximize profit while ensuring the fulfillment of the targeted hydrogen production by the end of the day. The optimization formulation incorporates electrolyzer maintenance, electricity, and water consumption costs. The model considered two cases with different electrolyzer efficiency values to optimize power usage, allowing for a comprehensive analysis of hydrogen production optimization. Ramping limits are imposed to maintain power system stability and reliability, preventing sudden fluctuations. By solving the formulated equations and considering factors such as energy and water prices, the research findings demonstrate the effectiveness of the bidding optimization approach in optimizing resource utilization and maximizing profit. Notably, the model successfully achieves the targeted hydrogen production by the end of the day while maximizing profit. This research contributes valuable insights into the bidding optimization process for hydrogen production, highlighting the potential for economic and sustainable hydrogen generation from electrolyzers.

Full text
Abstract:
Two major developments have recently emerged driving pipeline companies to re-evaluate transmix and regrade generation within their systems, along with the process which is the primary driver of transmix production — batch cutting. Dramatic increases in product cost and the advent of ultra low sulfur (ULS) regulation and ULS products have brought renewed focus on transmix generation and control. Given that pipeline tariffs are generally controlled by government agencies, and power cost can only marginally be controlled, transmix/regrade reduction and the corresponding savings is probably the last great revenue generator for pipelines and shippers. Batch cutting techniques and technology have remained largely unchanged for several decades. However, new technologies and greater automation have created renewed opportunities to significantly reduce transmix/regrade on a system-wide basis. Analysis has shown that projects related to transmix reduction are highly profitable and improve the overall precision and accuracy of batch cutting. This paper reviews the sources of variability in the manual batch cut process and how this variability can be eliminated through automation and new technologies.

Abstract:
In the conditions of market economy, non-profit organizations (NPOs) in the Republic of Moldova have long ceased to be only intermediaries between beneficiaries and donors. Being in constant search for sources of funding, they began to produce public goods and realize them, thus generating economic activity. Revenues of NPOs are formed both at the expense of attracted resources and at the expense of commercial activities. Recognition and assessment of revenues in accounting depends on the source of its formation The purpose of the article is to identify problematic aspects in the recognition and assessment of revenues in NPOs of the Republic of Moldova, taking into account the experience of Western countries and the latest recommendations provided as a result of the development of International Financial Reporting Standards applicable directly to non-profit organizations. This article gives a detailed description of the concept of "revenues" as it is presented in the accounting standards of different countries. The comparative characteristic of recognition and evaluation of income in Moldova with the experience of Western countries, where the share of NPOs in the GDP of the country is significant. The solution of existing problems in the field of methodology of accounting for revenues in NPOs in the Republic of Moldova will make it possible to bring financial statements closer to international requirements, making them more transparent and easy to read.

Abstract:
In 2010, high tech industries including computer makers, peripherals manufacturers, and medical equipment manufacturers spent a total of $8 billion on warranty. Reducing warranty costs improves the manufacturer’s profit and helps to reduce the overall cost of the product. An often cited principle is that approximately 80% of the eventual product cost is ‘locked in’ during the very early stages of product development; however, traditional methods of warranty analysis are not well suited to predict the warranty costs during these early stages. Thus, product development personnel need better tools to make good predictions about the warranty costs so that they can make better decisions to reduce those costs earlier in product development. In order to address this gap, previous research defined a warranty prediction framework, which at its core was a warranty event generation engine integrating the disparate data sources available early in the product development process. The objective of this work was to create an event generation model, which would give the probability of occurrence for a warranty event given the length of time of service for the system. The model developed in this work used three data sources: namely, field data, product development data, and engineering judgment data from our industrial partner. The datasets were then combined using a two-stage numerical Bayes method to predict the probability of occurrence of an event. Various test cases were created by using the different datasets as priors and likelihoods. The results were then compared to an actual field data set to understand how well the model performed. It was found that the model performed well and was able to produce a bounded solution. The paper closes by listing out the future research agenda to create a tool for product development professionals that will help them predict warranty costs.

Abstract:
The high-density plasmas produced by the interaction of short-pulse lasers with solid targets have been proposed as candidate coherent x-ray sources [1]. Large absorption of laser light and rapid cooling of the plasma—both of which are required for this scheme to work—depend strongly on the evolution of the electron-density profile during the laser pulse. We report experimental and theoretical results indicating that when the quiver energy of the electrons exceeds their thermal energy, the ponderomotive pressure of the laser significantly modifies the density profile.

Abstract:
Though a vast number of studies have been conducted on the various properties of intense field high order harmonic radiation, there have been no studies of the actual spatial coherence of optical harmonics at short wavelengths (&lt; 1000 Å). Measurements of harmonic far field profiles have suggested that the harmonics exhibited high coherence [1,2,3], but harmonic profile measurements alone are inadequate in determining the spatial coherence of the harmonic beam [4], To address this aspect of the harmonic generation, we have conducted a series of two-slit interference measurements on harmonics in the 270 Å to 480 Å range to determine unambiguously their spatial coherence properties.

Full text
Abstract:
Distributed energy storage has been recognized as a valuable and often indispensable complement to small-scale power generation based on renewable energy sources. Small-scale energy storage positioned at the demand side would open the possibility for enhanced predictability of power output and easier integration of small-scale intermittent generators into functioning electricity markets, as well as offering inherent peak shaving abilities for mitigating contingencies and blackouts, for reducing transmission losses in local networks, profit optimization and generally allowing tighter utility control on renewable energy generation. Distributed energy storage at affordable costs and of low environmental footprint is a necessary prerequisite for the wider deployment of renewable energy and its deeper penetration into local networks. Thermodynamic energy storage in the form of compressed air is an alternative to electrochemical energy storage in batteries and has been evaluated in various studies and tested commercially on a large scale. Distributed compressed air energy storage (DCAES) systems in combination with renewable energy generators installed at residential homes, public or commercial buildings are a viable alternative to large-scale energy storage, moreover promising lower specific investment than batteries if a mass-market is established. Flexible control methods can be applied to DCAES units, resulting in a complex system running either independently for home power supply, or as a unified and centrally controlled utility-scale energy storage entity. This study aims at conceptualizing the plausible distributed compressed-air energy storage units, examining the feasibility for their practical implementation and analyzing their behavior, as well as devising the possible control strategies for optimal utilization of grid-integrated renewable energy sources at small scales. Results show that overall energy storage efficiency of around 70% can be achieved with comparatively simple solutions, offering less technical challenges and lower specific costs than comparable electrical battery systems. Furthermore, smart load management for improving the dispatchability can bring additional benefits by profit optimization and decrease the payback time substantially.

In Applications of High Field and Short Wavelength Sources. Optica Publishing Group, 1997. http://dx.doi.org/10.1364/hfsw.1997.sab3.

Full text
Abstract:
For many nonlinear optics and high-field experiments, including high-order harmonic generation, X-ray lasers and particle acceleration, energetic pulses on the order of 10 fs and shorter would result in the observation of completely new phenomena. For example, calculations suggest that high-order harmonic generation with a 5 fs pulse would result in soft x-ray pulse with a duration on the order of 100 attoseconds. While 10 fs pulses are readily available at low energy (nJ) directly from Kerr-lens mode-locked laser oscillators, gain narrowing and high-order phase compensation have limited the pulse duration from ultra-short pulse laser amplifiers to about 20 fs. The route we are pursuing toward the goal of energetic sub-10 fs pulses is to compress amplified 20 fs pulses after self-phase modulation in a noble-gas-filled hollow-core dielectric waveguide, first used by Nisoli et al [1] for much longer input pulses. Along with the development of this technique, we have adapted the transient-grating frequency-resolved optical gating (TG-FROG) technique [2] for ultrashort, wide bandwidth pulse characterization. Since the guided pulse spectrum is broadened under the simultaneous action of several linear and nonlinear processes, including self-phase modulation, linear dispersion and self-steepening, the use of the FROG technique provides information necessary for optimal compression. Perhaps more important is that such coherent detection dramatically broadens the scope of experiments and applications using these pulses. For example, full characterization of amplitude and phase is crucial for control of the complex field profile.

Michel, Bob, and Tatiana Falcão. Taxing Profits from International Maritime Shipping in Africa: Past, Present and Future of UN Model Article 8 (Alternative B). Institute of Development Studies (IDS), 2021. http://dx.doi.org/10.19088/ictd.2021.023.

Full text
Abstract:
International maritime shipping is an essential part of global business. Since the establishment of the current international tax regime in the 1920s, there has been a consensus that profits generated by this business are taxable only in the residence state –the state where the shipowners are located. Source states – the port states where business physically takes place – are generally expected to exempt income from international shipping. This standard is currently reflected in Article 8 of the OECD Model and Article 8 (Alternative A) of the UN Model, and is incorporated in the vast majority of bilateral tax treaties currently in force. Exclusive residence state taxation of shipping profits is problematic when the size of mercantile fleets and shipping flows between two states are of unequal size. This is often the case in relations between a developed and developing country. The latter often lack a substantial domestic mercantile fleet, but serve as an important revenue-generating port state for the fleet of the developed country. To come to a more balanced allocation of taxing rights in such a case, a source taxation alternative has been inserted in UN Model Article 8 (Alternative B). From its inception, Article 8B has been labelled impractical due to the lack of guidance on core issues, like sourcing rules and profit allocation. This gap is said to explain the low adoption rate of Article 8B in global tax treaty practice. In reality, tax treaty practice regarding Article 8B is heavily concentrated and flourishing in a handful of countries in South/South-East Asia – Bangladesh, India, Indonesia, Myanmar, Pakistan, the Philippines, Sri Lanka and Thailand. All these countries subject non-resident shipping income to tax in their domestic income tax laws. Except for India, all countries are able to exercise these domestic tax law rules in relation to shipping enterprises located in the biggest shipowner states, either because they have a treaty in place that provides for source taxation or because there is no treaty at all and thus no restriction of domestic law. None of the relevant tax treaties contain a provision that incorporates the exact wording of Article 8B of the UN Model. If other countries, like coastal countries in sub-Saharan Africa, are looking to implement source taxation of maritime shipping income in the future, they are advised to draw on the South/South-East Asian experience. Best practice can be distilled regarding sourcing rule, source tax limitation, profit attribution and method of taxation (on gross or net basis). In addition to technical guidance on tax, the South/South-East Asian experience also provides important general policy considerations countries should take into account when determining whether source taxation of maritime shipping profits is an appropriate target for their future tax treaty negotiations.

Full text
Abstract:
The goal of this paper is to introduce FABLE (Forest, Agriculture, and Biofuels in a Land use model with Environmental services), a dynamic global model, aimed at analyzing the optimal profile for global land use in the context of growing commercial demands for food and forest products, increasing non-market demands for ecosystem services, and more stringent greenhouse gas mitigation targets. The model seeks to determine the optimal allocation of scarce land across competing uses across time. FABLE integrates distinct strands of agronomic, economic and biophysical literatures into a single, intertemporally consistent, analytical framework, at global scale. It is based on a dynamic long-run, forward-looking partial equilibrium framework, in which the societal objective function places value on food production, liquid fuels (including first- and second- generation biofuels), timber production, forest carbon and biodiversity. The forestry sector is characterized by multiple forest vintages, which add considerable computational complexity in the context of this dynamic forward-looking analysis. Our baseline accurately reflects developments in global land use over the years that have already transpired, and determines the optimal path of global land use over the course of next century based on projections of population, income and demand growth from a variety of recognized sources.
