Résumé :

This study analyses the changes that gas turbines have brought in the field of air and land transport and technology. The worldwide production of gas turbines includes the commercial and military aviation markets, as well as non-aviation markets for electrical generation, marine applications, and mechanical power. In recent years, gas turbine combined-cycle plants have become key players in the generation of electric power. Aviation gas turbines make up the largest segment, whereas, the non-aviation gas turbine market is characterized by a particular vitality and volatility. The original equipment manufacturers (OEM) who supply large gas turbine combined-cycle plants are General Electric (GE), Siemens, Mitsubishi, and Alstom. And soon, the industry will be consolidated further, as GE is in the process of acquiring the power segment of Alstom, thus narrowing the field of large plant OEMs to a big three – similar to the threesome in aviation: GE, Rolls-Royce, and Pratt & Whitney – with GE in the lead.

Résumé :

Nord Pool is the leading power market in Europe. It has been documented that the forward contracts traded in this market exhibit a significant forward premium, which could be a sign of market inefficiency. Efficient power markets are important, especially when there is a goal to increase the share of the power mix stemming from renewable energy sources. We therefore contribute to the understanding of this topic by examining how the forward premium in the Nord Pool market depend on several economic and physical conditions. We utilise two methods: ordinary least squares and quantile regression. The results show that the reservoir level and the basis (the difference between the forward and spot price) have a significant impact on the forward premium. The realised volatility of futures prices and the implied volatility of the stock market have strong effects on both the conditional lower and upper tails of the forward premium. We also find that, as the market has matured, the forward premium has decreased, indicating an increase in market efficiency.

Résumé :

Increasing variable renewable power generation (e.g., wind) is expected to reduce wholesale electricity prices by virtue of its low marginal production cost. This merit-order effect of renewables displacing incumbent conventional (e.g., gas) generation forms the theoretical underpinning for investment decisions and policy in the power industry. This paper uses a game-theoretic market model to investigate how intermittently available wind generation affects electricity prices in the presence of forward markets, which are widely used by power companies to hedge against revenue variability ahead of near-real-time spot trading. We find that in addition to the established merit-order effect, renewable generation affects power prices through forward-market hedging. This forward effect reinforces the merit-order effect in reducing prices for moderate amounts of wind generation capacity but mitigates or even reverses it for higher capacities. For moderate wind capacity, uncertainty over its output increases hedging, and these higher forward sales lead to lower prices. For higher capacities, however, wind variability conversely causes power producers to behave less aggressively in forward trading for fear of unfavorable spot-market positions. The lower sales counteract the merit-order effect, and prices may then paradoxically increase with wind capacity despite its lower production cost. We confirm the potential for such reversals in a numerical study, suggesting new empirical questions while providing potential explanations for previously contradictory observed effects of market fundamentals. We conclude that considering the conventional merit-order effect alone is insufficient for evaluating the price impacts of variable renewable generation in the presence of forward markets.

Résumé :

The issue of whether vertical integration can raise market power is hotly debated because firms have a market power-related incentive to integrate vertically. Using a sample of U.S. food manufacturing industries, this “market power” motive is empirically tested in this study. Empirical analysis shows that forward vertical ownership integration (or vertical mergers) did not increase food manufacturers' market power in the final product market. The study, however, shows that both market structure and conduct significantly influenced market power in the food industries.

Résumé :

Renewable energy sources produce less environmental impact and have little marginal cost. Thus, because of these characteristics, it is desirable to disseminate it for the purpose of economic efficiency. Because of the uncertainty in the supply of renewable energy and the special feature of electricity as a good, such as merit order curve, introducing forward markets is an essential factor in a liberalized market. In European countries, which have already established several mechanisms for managing liquidity including markets with several timelines, the market liquidity invites the investor to perform some speculative action. We present a simple electric power market model to analyze the speculative actions of electricity suppliers and the price effect of such actions. Moreover, we found that the speculative action improves the inelasticity of the demand in electricity market.

Résumé :

The world’s energy system is undergoing an evolution from high-carbon to low-carbon. The Chinese government has also proposed the carbon neutral plan. Foreign practical experience shows that there is an interaction between the carbon market and the electricity market, therefore, understanding the relationship between the two markets is essential to ensure the efficient operation of both markets. In the context of China's power market reform, this paper studies the impact of introducing carbon prices into the wholesale market, and conducts a case study based on the data of a certain area in GD province. The results show that after the carbon price is transmitted to the electricity price, the more low-carbon and environmentally friendly power generation technologies will gain greater advantages in the electricity market, which is conducive to the clean energy transformation of the power system. Finally, this paper puts forward feasible suggestions for the reform of the electricity market under China’s carbon emission reduction target.

Résumé :

Regional and sub regional markets development is one of the main aspects of integration, which is common in modern world. Integration process affects greatly global economic, trade, infrastructure and energy cooperation between the states.Energy markets become less manageable, energy security global structure is also changing. EEU is a part of this trend, country-members of which is one of the world’s biggest energy regions. Union countries has already formed common customs territory, which allows to provide free finance flow and people’s movement. Mutual trade in 2017 increased by 19% compared to 2015 year. But there are few problems, which slow down integrational process. All country’s equal rights to affect decision — making on the one hand provide to smaller countries an ability to protect their interests, on the other — delay common decision making.Common power market is important step forward to complex integration, which anticipated EEU common gas and oil markets. EEU energy sector operates common soviet-period infrastructure using unified standards. Creation of common power market will boost trade and economic cooperation between the EEU members. However, different energy potential, level of industry development, different schemes of EEU energy market operations complicate the whole EEU integration process.

Résumé :

Increasing consolidation and vertical coordination in the food chain have made the prospect of market power abuses by powerful food manufacturers and retailers an issue and a policy concern worldwide, in terms of potential impacts on farmer and consumer welfare and sector efficiency. We address the extent to which traditional wisdom and standard conceptual and empirical models that have girded thought about market power in the food chain for decades apply in modern food-market contexts and examine recent work on competition in the food chain to gauge the most promising paths forward. A key conclusion is that considerations that go beyond the bounds of standard models likely cause market power to be less than would be predicted based on the highly concentrated structures of many modern agricultural and food markets. These considerations include downstream buyers who rationally internalize long-run implications of their pricing decisions to farmers, powerful food manufacturers and retailers who countervail each other's market power, and the complex pricing decisions of multistore and multiproduct food retailers.

Résumé :

We examine forward prices in a market where nonstorable inventory exacerbates the influence of seasonal and hourly variation in supply and demand, expected and unexpected, on the level and volatility of spot prices. We find strong evidence, unusual for a commodity, that the difference between contemporaneous forward and spot prices has power to forecast both the spot price change and the risk premium realized at delivery. Our evidence of a time-varying risk premium is consistent with expected hourly and seasonal variation in the needs of producers and retailers of electricity to hedge against extreme spot price decreases and increases, respectively.

Résumé :

The thermal problems of high power LEDs could be solved effectively and the stability of the device could be also improved, employing metal substrates for high power LEDs. In this paper,high power GaN based blue LEDs on metal substrates were successfully prepared by transferring GaN-based LED epitaxial film on Si (111) substrates to the Cu/Cr composite substrates employing electroplating method. The forward voltage of the as-prepared LEDs was 3.4 V, when the forward operating current was 350 mA, which was similar with the level of market products. The corresponding voltage could reach 25 V when reverse current was 10 μA, better than the level of market products. It showed good anti-saturation property when forward current varied from 0 mA to 1200 mA. The stability of wavelength vs current was also favourable, which the peak wavelength shifted to long wavelength about 1nm in the test range of 10 mA to 1200 mA.

Résumé :

Forward electricity market has emerged as a pivotal section for the electricity transaction to keep stakeholders away from price risk and electricity shortage. But the forward contract of conventional unit partially limits the unit output before operation, leading to the curtailed generation share of renewable energy source (RES). Modeling and assessing this impact is of great significance for system planning and market supervision. The central thesis of this paper is to find out the impact of forward market on RES curtailment. A probabilistic evaluation model for RES accommodation is proposed, taking the curtailment rate as a main evaluation index. We mainly research financial contract and physical contract, modeling the impact of them on thermal unit minimum load capacity and power load in evaluation model. The simulation is conducted in a simplified system, which reveals the change of RES curtailment with renege penalty, contract price and execution generation curve.

Texte intégral

Résumé :

For the benefit from accurate electricity price forecasting, not only can various electricity market stakeholders make proper decisions to gain profit in a competitive environment, but also power system stability can be improved. Nevertheless, because of the high volatility and uncertainty, it is an essential challenge to accurately forecast the electricity price. Considering that recurrent neural networks (RNNs) are suitable for processing time series data, in this paper, we propose a bidirectional long short-term memory (LSTM)-based forecasting model, BRIM, which splits the state neurons of a regular RNN into two parts: the forward states (using the historical electricity price information) are designed for processing the data in positive time direction and backward states (using the future price information available at inter-connected markets) for the data in negative time direction. Moreover, due to the fact that inter-connected power exchange markets show a common trend for other neighboring markets and can provide signaling information for each other, it is sensible to incorporate and exploit the impact of the neighboring markets on forecasting accuracy of electricity price. Specifically, future electricity prices of the interconnected market are utilized both as input features for forward LSTM and backward LSTM. By testing on day-ahead electricity prices in the European Power Exchange (EPEX), the experimental results show the superiority of the proposed method BRIM in enhancing predictive accuracy in comparison with the various benchmarks, and moreover Diebold-Mariano (DM) shows that the forecast accuracy of BRIM is not equal to other forecasting models, and thus indirectly demonstrates that BRIM statistically significantly outperforms other schemes.

Résumé :

Combined with the electric power market dynamic model put forward by Alvarado, an interval model of electricity markets is established and investigated in this paper pertaining to the range of demand elasticity with suppliers and consumers. The stability of an electricity market framework with demand elasticity interval is analyzed. The conclusions characterizing the interval model provided are derived by constructing a suitable Lyapunov function and using the theory of interval dynamical system in differential equations and matrix inequality theory and so forth. Applying the corollary obtained can judge the system stability by available data about demand elasticity. The obtained results are validated and illustrated by a case example.

Résumé :

Purpose – This paper aims to present a multi-period dynamic power project financing model to produce pragmatic estimates of benchmark wholesale power prices based on the principles of normal profit. This, in turn, can guide policymakers as to whether price spikes or bidding above marginal cost in wholesale electricity markets warrants any investigation at all. One of the seemingly complex areas associated with energy-only wholesale electricity pools is at what point market power abuse is present on the supply side. It should not be this way. If a theoretically robust measure of normal profit exists, identification of potential market power abuse is straightforward. Such a definition readily exists and can be traced back to the ground-breaking work of financial economists in the 1960s. Design/methodology/approach – Using a multi-period dynamic power project model, the authors produce pragmatic and theoretically robust measures of normal profit for project financed plant and plant financed on balance sheet. These model results are then integrated into a static partial equilibrium model of a power system. The model results are in turn used to guide policymaking on generator bidding in energy-only power markets. Findings – Under conditions of perfect plant availability and divisibility with no transmission constraints, energy-only markets result in clearing prices which are not economically viable in the long run. Bidding must, therefore, deviate from strict short-run marginal cost at some stage. To distinguish between quasi-contributions to substantial sunk costs and market power abuse, a pragmatic and robust measure of normal profit is required. Originality/value – This article finds policymakers can be guided by an ex-post analysis of base energy prices against pragmatic estimates for the long-run marginal cost of the base plant, and an ex-ante analysis of call option prices along the forward curve against pragmatic estimates of the carrying cost of the peaking plant.

Résumé :

In the electricity market environment, thermal power units have changed from the executors of power production under the monopoly mechanism to the decision-makers of production and operation under the competitive environment. The merits and demerits of bidding schemes for thermal power units are directly related to self-interest of themselves. The bidding decisions of power plants are not only affected by economic factors, but also by technical factors peculiar to the power system and the electric generator. In recent years, research on bidding strategies of thermal power units based on the power market environment has been paid more and more attention in the field of electric market. This paper first introduces the basic peak regulation and frequency modulation technical characteristics of thermal power units and cost calculation. Then, from the angle of quotation, paper analyzes characteristics of quotation mechanism of units in Fujian Electric Power day-ahead, real-time and peak regulation auxiliary service market. Furthermore, the research status of bidding strategies of thermal power units participating in electricity market at home and abroad in cost analysis, market clearing price prediction, game theory and so on are summarized. Finally, the bidding strategy for units in Fujian Spot Market is put forward.

Résumé :

The coal consumption of China reached 2.75 billion tons of standard coal in 2013, which accounted for 67.5% of total energy consumption and more than 50% of global coal consumption. Therefore, the impact of coal price is huge on coal market and even energy market in China. As a large consumer of coal, thermal power enterprise has a strong sensitivity to coal price. In order to balance the rising cost of enterprises due to coal price, we need to analyze the interests of multiple stakeholders. Firstly, this paper combined the Nash equilibrium and cobweb model and proposed the characteristics in different cobweb model. Then, for coal, power, and energy companies, the dynamic game analysis model is constructed. This model gives a game analysis in four scenarios and quantifies the decision of each stakeholder in different coal prices. Finally, the impact figure of different coal prices on each stakeholder has been drawn. The impacts of different coal or thermal power prices on different markets have been put forward, so relevant policy recommendations have been proposed combined with the cobweb model.

Texte intégral

Résumé :

Markups vary systematically across firms and are a source of misallocation. This paper develops a tractable model of firm dynamics where firms' market power is endogenous and the distribution of markups emerges as an equilibrium outcome. Monopoly power is the result of a process of forward‐looking, risky accumulation: firms invest in productivity growth to increase markups in their existing products but are stochastically replaced by more efficient competitors. Creative destruction therefore has pro‐competitive effects because faster churn gives firms less time to accumulate market power. In an application to firm‐level data from Indonesia, the model predicts that, relative to the United States, misallocation is more severe and firms are substantially smaller. To explain these patterns, the model suggests an important role for frictions that prevent existing firms from entering new markets. Differences in entry costs for new firms are less important.

Résumé :

In recent years, the scale of wind power development is increasing in southwest. The space of power accommodated capacity has become an important factor in the development of wind power. Combining with the characteristics of the electricity market development in southwest, this paper uses the power balance to research the wind power admitting ability. By comparison, a forecasting method which is based on the gray method to forecast the minimum value of main net power is put forward. According to the characteristics of the supply and power balance in the region, the wind power admitting capacity is forecasted. Finally, after the actual simulation, compared with conventional forecasting the method is proved to have high precision and more accurate to predict the local wind power accommodated capacity.

Résumé :

Nigerians once trusted power cables to be safe and compliant with international standards. Today, however, the Nigerian market is rife with substandard cables, which may overheat, shoot out sparks, and cause fires. Power cables have been transformed from commodities with stable and precisely defined properties into entangled objects that can only be known through the actors accompanying them. Marketization scholarship has conventionally focused on efforts and investments to disentangle things from their networks of connections, affording less attention to the specifics of how entanglements are produced. This article examines the role of intermediation in creating entanglements and undermining market orders. The analysis first identifies intermediaries that endeavor to translate the market logic into concrete realities in Nigeria. The second and main part of the analysis draws upon data from ethnographic fieldwork in Nigeria and China to assess how intermediaries destabilized the commodity of cables by forging new connections between traders and producers and by enabling inferior products to enter the market. The article proposes intermediation as a meso-level concept for connecting concrete and empirically observable events to theories of marketization. The approach moves marketization scholarship forward and away from its oft-vague operationalizations, while also suggesting new avenues for research on intermediation beyond the study of markets.

Résumé :

In Chinas semi-deregulated electricity market, a game-theoretic model has been set between users and power suppliers in order to ensure the whole network voltage load curve stay smooth, as well as to make the suppliers profitable on the basis of the satisfaction of users in power utilization in daily lives. The foundation of the model is the definition of the price elasticity of demand and its characters in micro-economy. According to this model, a Bayesian Nash equilibrium has been put forward based on the demand price elasticity, which can not only smooth the whole network voltage load curve effectively through the reciprocal process between users and power suppliers, but also can optimize the profit of the power suppliers. The simulation results of the voltage load curves and price changes graphs show the effectiveness of modeling simulation.

Résumé :

As an effective measure for the promotion of the adjustment of China’s energy structure, distributed energy and its reasonable planning and development will have a significant impact on the major players in China’s power market. With the increasing access to distributed energy, its beneficial impact on the major players in the power market will become increasingly obvious. This paper examines the influence of access to distributed energy on the development of the major players in the power market, especially power supply enterprises. On this basis, a model for the calculation of the profits and losses of distributed energy users and power supply enterprises has been established, and the specific impact on the profits of power supply enterprises after access to distributed energy becomes available can be measured. In addition, this paper puts forward related policy suggestions to be implemented after access to distributed energy becomes available based on the results of the aforementioned measurement, in order to guarantee a reasonable profit for the major players in the power market during the process of the development of distributed energy and to promote the healthy and orderly development of distributed energy.

Résumé :

To support the development of the PV industry, the China National Energy Bureau has issued some policies to stimulate the domestic PV market consumption, such as the “Golden Sun Demonstration Project”, “Building Integrated PV” policy. But these policies have some great vulnerability. Many developed countries, such as Germany, Japan, USA; they have some mature PV price settlement policies, such as Feed-in Tariff, Net Metering and Self-Consumption. Therefore, according to the needs of domestic situation, China National Energy Bureau needs to refer to those developed countries’ mature PV price settlement policies to formulate a PV price settlement policy. This policy must suit China PV market. And this policy should guide the development of domestic PV market correctly. Herein, I put forward some recommendations to improve our PV price settlement policy.

Résumé :

The author analyses the performance of the United Kingdom's ‘Renewables Obligation’ (RO) in the context of other renewable energy procurement regimes. Prevailing wisdom suggests that market-based procurement regimes for renewable energy are more cost-effective than fixed-price (‘feed-in tariff’) arrangements. In addition, market-based regimes are thought to favour corporate, rather than locally owned, schemes. However, the analysis in this paper disputes these strands of conventional wisdom. An analysis of the returns to wind-power developers under the British market-based RO and the German ‘renewable energy feed-tariff’ (REFIT) reveals that financial returns per MW of installed capacity are much higher in the case of the market-based British RO than in the German REFIT. On the other hand, there is evidence that cultural factors are a bigger influence on the patterns of ownership of wind-power schemes than whether procurement systems are market based or fixed price.

Résumé :

Electric power industry is the foundation of national economy and plays a key role in the development of human society. Traditional power industry is monopolized by industry and lacked of market efficiency. In recent years, it is seeking breakthroughs in the market-oriented reform. Although China’s electricity market reform has achieved some achievement, it is still lacked of market players, regional transactions, excessive data management, concentration and other defects. This paper puts forward higher requirements for the system design of power market transactions. The electrical power market is facing with the security and performance challenges, it is to improve the electrical power market transaction mode and to enhance transaction security, blockchain is a new decentralized framework and with a distributed computing paradigm, which integrates and innovates a variety of computer technologies, then it constructed a perfect competitive electricity market system. Using of different levels of multi auction trading model to integrate the province’s trading and inter provincial trading parts in one system. In the part of inter-province trading, it adopted the contract trading and bidding coexist pattern, the trade is carried out in each province Surplus-deficit electricity which based on the meet of the province’s demand basis. By using blockchain, it can conducted the intelligent contract and record the whole transaction information discretely, and provided the inquiry transaction channel to the users, so it can achieve the resource scheduling fairness and transaction information in security.

Résumé :

Energy transactions in liberalized markets are subject to price and quantity uncertainty. This paper considers the spot price and energy generation to follow a bivariate semi-nonparametric distribution defined in terms of the Gram–Charlier expansion. This distribution allows us to jointly model not only mean, variance, and correlation but also skewness, kurtosis, and higher-order moments. Based on this model, we propose a static hedging strategy for electricity generators that participate in a competitive market where hedging is carried out through forward contracts that include a risk premium in their valuation. For this purpose, we use Monte Carlo simulation and consider information from the Colombian electricity market as the case study. The results show that the volume of energy to be sold under long-term contracts depends on each electricity generator and the risk assessment made by the market in the forward risk premium. The conditions of skewness, kurtosis, and correlation, as well as the type of the employed risk indicator, affect the hedging strategy that each electricity generator should implement. A positive correlation between the spot price and energy production tends to increase the hedge ratio; meanwhile, negative correlation tends to reduce it. The increase of forward risk premium, on the other hand, reduces the hedge ratio.

Résumé :

“Penetration” supervision is an important topic concerned in the academic field of China’s financial law recently. On October 13, 2016, the General Office of the State Council officially put forward the concept of “penetrating” supervision, stating that “it is necessary to base on practice and research to solve the financial problems which exposed in the finance field”. Although “penetrating” regulation is a specific concept proposed for the special rectification of Internet financial risks, it has quickly gained the support of many scholars as soon as it is proposed, and some scholars even recommend it to be extended to the entire financial market. This paper focuses on the practice of China’s financial market, defines the connotation of “penetrating” supervision, sorts out the theoretical basis of “penetrating” supervision, types the Chinese-style “transparent” supervision. The realization path of supervision is to optimize the allocation of financial regulatory power and promote the healthy development of the market.
