Abstract:
<span lang="EN-US">This paper presents a battery-less power supply using supercapacitor as energy storage powered by solar. In this study the supercapacitor as energy storage, as opposed to batteries, has widely researched in recent years. Supercapacitors act like other capacitors, but their advantage is having enormous power storage capabilities. Maximum charging voltage and capacitance are two variables of storage in the supercapacitor. The supercapacitor is used as energy storage to charge a low power device wirelessly and act as a power supply. The solar energy is used as a backup power supply if there is no electricity in the remote or isolated area to charge the supercapacitor. The time taken to charge the supercapacitor depend on the amount of current rating of the solar panel. The higher the current, the shorter the time taken to charges the supercapacitor. Power supply using supercapacitor can store up to 30 Vdc using a DC-DC boost converter.</span>

Abstract:
The use of nonrenewable fossil fuels for energy has increased in recent decades, posing a serious threat to human life. As a result, it is critical to build environmentally friendly and low-cost reliable and renewable energy storage solutions. The supercapacitor is a future energy device because of its higher power density and outstanding cyclic stability with a quick charge and discharge process. Supercapacitors, on the other hand, have a lower energy density than regular batteries. It is well known that the electrochemical characteristic of supercapacitors is strongly dependent on electrode materials. The current review highlights advance in the TMOs for supercapacitor electrodes. In addition, the newly discovered hybrid/pseudo-supercapacitors have been discussed. Metal oxides that are employed as electrode materials are the focus of this study. The discovery of nanostructured electrode materials continues to be a major focus of supercapacitor research. To create high-performance electrode materials from a morphological standpoint, various efforts have been attempted. Lastly, we analyze the supercapacitor’s evolving trend and our perspective for the future generations of supercapacitors.

Abstract:
With greater power density, a hybrid power source that combines supercapacitors and batteries has a wide range of applications in pulse-operated power systems. In this paper, a supercapacitor/battery semi-active hybrid energy storage system (HESS) with a full current-type control strategy is presented. The studied HESS is composed of batteries, supercapacitors, and a bidirectional buck–boost converter. The converter is controlled such that supercapacitors supply load power pulses, and batteries provide the power in steady state. To realize the fast compensation of the supercapacitors to the load power pulses, a power distribution module based on hysteresis control theory is designed in the control system. Moreover, the control strategy does not require the model parameters of the converter and supercapacitors, so the control system is simplified. A complete configuration scheme and cost analysis of the proposed HESS are also presented. Obtained results show that the proposed supercapacitor/battery semi-active HESS has good performance in terms of dynamic response, weight, and energy utilization coefficient (EUC).

Abstract:
The demand for renewable energy sources worldwide has gained tremendous research attention over the past decades. Technologies such as wind and solar have been widely researched and reported in the literature. However, economical use of these technologies has not been widespread due partly to cost and the inability for service during of-source periods. To make these technologies more competitive, research into energy storage systems has intensified over the last few decades. The idea is to devise an energy storage system that allows for storage of electricity during lean hours at a relatively cheaper value and delivery later. Energy storage and delivery technologies such as supercapacitors can store and deliver energy at a very fast rate, offering high current in a short duration. The past decade has witnessed a rapid growth in research and development in supercapacitor technology. Several electrochemical properties of the electrode material and electrolyte have been reported in the literature. Supercapacitor electrode materials such as carbon and carbon-based materials have received increasing attention because of their high specific surface area, good electrical conductivity and excellent stability in harsh environments etc. In recent years, there has been an increasing interest in biomass-derived activated carbons as an electrode material for supercapacitor applications. The development of an alternative supercapacitor electrode material from biowaste serves two main purposes: (1) It helps with waste disposal; converting waste to a useful product, and (2) it provides an economic argument for the substantiality of supercapacitor technology. This article reviews recent developments in carbon and carbon-based materials derived from biowaste for supercapacitor technology. A comparison between the various storage mechanisms and electrochemical performance of electrodes derived from biowaste is presented.

Supercapacitor is widely used in high power energy storage device, and its charge and discharge properties decide the energy storage devices of important performance indicators. In this paper, in order to research the charging performance of supercapacitors, a constant current test system which is based on microcontroller was designed. The system use a program-controlled constant current source which focuses on high-power MOSFET in accordance with the current data gotten from the sampling circuit, adjust the output current by PID algorithm, and thereby enhance the controlling precision of the output of the constant current. Under the combined control between upper machine and lower machine, the test system can map out potential function curve following time-varying, so that the supercapacitor’s charge process implement visualization. The result which tests the supercapacitor shows that the circuit has a simple structure and the current is very stable, which can be applied to all kinds of energy storage device which requires high current for charge and property test.

Abstract:
Supercapacitors (SCs) are a form of energy storage that fills the vacuum left by traditional capacitors and batteries. They have greater energy storage capacity than capacitors and can deliver electricity at higher rates than batteries. Both the capacitor and supercapacitor have two electrodes (plates) separated by a dielectric, however super capacitors have electrodes with a larger surface area and thinner dielectrics, allowing for higher energy densities. Super capacitors are extensively employed in portable electronic devices due to its high storage capacity. The design, properties, and uses of supercapacitors are briefly discussed in this article.

Abstract The paper describes the application of supercapacitor energy storage system for induction traction drive test bench that replaces a real electric public transport for performing testing and researches. The suitability and usage of such bench for research purposes is explained and the importance of the development of software mathematical model for performing simulations to be done before physical implementation measures is reasoned. The working principle of the bench and applied components are described. A virtual model of the bench was built and simulations were performed using Matlab/Simulink software. The basic topology of the virtual bench model is described as well. The calculations of this work show the scaling of supercapacitor energy storage system by setting different limits of working voltage range in order to adjust them to test bench parameters, whereas the modelling compares two simulation cases – the application of less supercapacitors and the application of more supercapacitors with the same common rated voltage. The autonomous mode simulations were also performed. Simulation results are analyzed and recommendations for the application of the supercapacitor energy storage system, with respect to initial supercapacitor circuit voltage, are given.

Abstract:
The increasing interest in Hybrid Electric Vehicles led to the study of new powertrain structures. In particular, it was demonstrated in the technical literature how series architecture can be more efficient, compared to parallel one, if supercapacitors are used as storage system. Since supercapacitors are characterized by high efficiency and high power density, but have low specific energy, storage sizing is a critical point with this technology. In this study, a detailed analysis on the effect of supercapacitor storage sizing on series architecture was carried out. In particular, in series architecture, supercapacitor storage sizing influences both engine number of starts and the energy that can be stored during regenerative braking. The first aspect affects the comfort, whereas the second aspect directly influences powertrain efficiency. Vehicle model and Energy Management System were studied and simulations were carried out for different storage energy, in order to define the optimal sizing.

Abstract:
The supercapacitor, as a recently developed electrochemical energy storage device, offers extremely high capacitance per unit volume. Due to its unique double-layer structure and electrostatic charge mechanism, the supercapacitor has a much higher power density than the battery, and a much higher energy density than the conventional capacitor. It also benefits from a long cycle life, and wide temperature range. However, limited by a low cell voltage of 2.7V and high equivalent series resistance, the supercapacitor may be inefficient for high power grid level applications. Characteristic analysis of the supercapacitor shows that the efficiency reduces to 54.7% at peak current conditions. Based on supercapacitor modelling studies, two parameter identification methods are proposed, which are realised by a simple experiment, with an acceptable accuracy. A parallel combined supercapacitor and electrolytic capacitor energy storage system is proposed to improve high power application performance, which offers efficiency improvements in excess of 10%. A detailed description of such parallel capacitor systems are included in this thesis, where a design guide is developed to achieve an optimal design in terms of system efficiency, power capability, and volume. The capacitor based energy storage technique is suited to distributed generation applications where low-voltage ride through and grid code compliance are important considerations. A supercapacitor based static synchronous compensator is proposed, which is able to manipulate both active and reactive power exchange with the power system. Steady-state and transient responses are studied based on simulation of a test power system. A system frequency based control algorithm is used for active power control, which has a better stabilised system frequency than with conventional voltage control. The parallel hybrid capacitor technique is employed, which greatly improves the system performance in terms of efficiency, thermally, costs, and volume, compared with a system that only uses supercapacitors.

Abstract:
STATCOM (STATic COMpensator) has been used in electrical power systems as a shunt-connected compensator for voltage support and to improve power quality. Compared with the conventional compensators such as the synchronous condenser and the SVC (Static Var Compensator), the STATCOM has a faster speed of response to deal with dynamic and transient impacts. Although the STATCOM is capable of reactive power support to improve power quality, the ability to support real power is limited due to the insufficient energy storage capability of the conventional DC-link capacitor. Therefore, the application of the STATCOM to improving power system stability has been limited. This thesis proposes a solution to enhance the performance of the STATCOM by adding supercapacitor energy storage to the DC-link of the conventional STATCOM. With the fast charge/discharge characteristics of the supercapacitors, the enhanced STATCOM can absorb and inject real power to the ac power grid virtually instantaneously. The control design of the STATCOM based on a vector control strategy is presented, including the design of an instantaneous reactive power controller based on a small-signal model of the ac power system. The control design of the supercapacitor energy storage system (SCESS) based on small-signal models of the de-to-de converter is documented. The STATCOM and the SCESS are controlled together using a feed-forward control technique. In addition, this thesis also proposes that the enhanced STATCOM can be applied to reduce instability and tripping due to the rate of change of frequency (ROCOF) protection devices caused by large load impacts. The amount of the energy required for the enhanced STATCOM to maintain the stability of the system is also discussed.

Abstract:
Fiber supercapacitors (FSCs) are promising energy storage devices for emerging wearable electronics due to their unique advantages, such as good flexibility, weaveability and integratablity. Graphene materials with high surface area and excellent conductivity have been explored as electrode materials for fabricating FSCs. However, there are some many challenges to be resolved before they can be used in practical devices. This thesis focuses on three critical issues. First, when graphene materials are assembled as graphene hydrogel fibers, they shrink significantly during drying accompanied by complex internal structural transforms, which affect their energy storage performance significantly. However, the vital drying process has been largely ignored in previous studies. Second, when assembling graphene nanosheets into graphene electrodes, they often stack together uncontrollably due to strong van der Waals interactions between adjacent nanosheets, which significantly compromise their energy storage performance, This phenomenon has limited the applications of graphene fibers, even though they have high theoretical specific capacitance. Third, although graphene material based electrodes often deliver high power and long cycle life, their energy storage capacity based on the electrochemical double-layer capacitance is often limited. How to efficiently incorporate pseudocapacitive materials into graphene fibers to increase energy storage density is still unclear. To address these three issues, first, a comprehensive study was conducted to investigate the effects of drying conditions of graphene fibers on their porous structures and electrochemical properties. Graphene fibers were dried systematically under five different representative drying conditions. It was found that (1) the d-spacing of graphene nanosheets is determined during their reduction in hydrothermal assembly; (2) pore structures of dried graphene fibers are significantly influenced by solvent removal rates during drying; (3) the interconnection of pores in graphene fibers can be retained if non-volatile solvents are trapped in hydrogel fibers and (4) the graphene fibers dried under different conditions show significantly different specific volumetric capacitance and rate capability in capacitive energy storage. These findings can guide the synthesis of 1D fibers from 2D materials for FSCs and beyond. Second, a 2D-covalent organic framework (2D-COF) with a thickness of around 2 nm was explored as a nano-spacer to prevent the stacking of reduced graphene oxide (rGO) nanosheets during their assembly. The 2D-COF was selected because its mesopores can serve as an efficient “highway” for ion diffusion. The rGO/COF hybrid delivered a high gravimetric capacitance of 321 F g–1, corresponding to an ultrahigh graphene utilization rate (74%) related to theoretical gravimetric capacitance of graphene. Further, its practical applications were demonstrated in both thin-film supercapacitors and FSCs. They delivered a high specific energy density of 10.3 Wh kg−1 (thin-film supercapacitors) or 7.9 mWh cm−3 (FSCs), respectively. The 2D-COF shows good potential to enhance the energy storage performance of graphene or other 2D materials. Third, a novel method was demonstrated to uniformly incorporate ruthenium oxide (RuO2) nanoparticles with an ultra-high mass loading of 42.5 wt.% into holey graphene oxide (HGO) fibers. The HGO fibers were first prepared by the hydrothermal assembly. Next, Ru3+ ions were incorporated into wet HGO fibers before drying. The resulting composite fibers exhibited an ultrahigh volumetric capacitance of 1054 F cm−3. Solid-state FSCs fabricated by these fibers showed an ultrahigh energy density of 27.3 mWh cm−3. This method has the general applicability to incorporate different pseudocapacitive materials into graphene fibers to increase their energy storage capacity. Forth, to further increase the electrical conductivity of hybrid fibers containing pseudocapacitive materials, a core-sheath fiber comprised of a graphite fiber core and a MoS2 nanosheet intercalated HGO sheath was designed and synthesized by the hydrothermal assembly. MoS2 was selected due to its high pseudocapacitance and conductivity. The graphite fiber core served as a faster electron transfer highway. The core-sheath fiber showed a high volumetric capacitance up to 421 F cm−3. It was found that more than half of the capacitance of the fiber can be retained when the scan rate increases from 2 to 100 mV s–1. The assembled solid-state FSC delivered a high energy density of 8.2 mWh cm−3 at the power density of 40 mW cm−3. Overall, this thesis has provided new fundamental understandings of the assembly of graphene materials. Several innovative methods were demonstrated to produce high-performance graphene-based electrodes for FSCs. These results will help to realize of various potential practical applications of FSCs based on graphene materials

Abstract:
In this work we have investigated supercapacitor electrodes prepared from pure and 1-pyrenecarboxylic acid (PCA)-functionalized graphene flakes obtained from liquid phase chemical exfoliation method. The performances of the supercapacitor devices fabricated using the graphene electrodes were tested using cyclic voltammetry, constant current charging-discharging and by electrochemical impedance spectroscopy (EIS) The specific capacitances obtained (using 6M KOH aqueous solution as an electrolyte) were found to be ~ 30 F/g and ~ 200 F/g for pure graphene and PCA functionalized graphene electrodes respectively. A comprehensive understanding of the effect of surface fictionalization on the electrochemical double layer capacitance was obtained in the light of equivalent circuit modeling and EIS data analysis. Information obtained from the EIS spectrum analysis revealed the possibility of occurrence of pseudocapacitance due to the presence of surface functional groups on the graphene flakes. Further, the wettability by KOH significantly increases upon functionalizing the graphene surfaces. These results shows PCA functionalized graphene membrane electrodes have the potential for high performance as supercapacitor electrode material.

Abstract:
The objective of this thesis was to investigate the suitability of some different Li4Ti5O12 materials as a negative electrode in hybrid supercapacitors. A hybrid supercapacitor is a combination of a battery and an electric double-layer capacitor that uses both a battery material and a capacitor material in the same device. The target for these combination devices is to bridge the performance gap between batteries and capacitors and enable both high energy and power density. To achieve this, materials with high capacity as well as high rate capability are needed. To improve the rate of the commonly slow battery materials nanosizing has been found to be an effective solution. This study shows that Li4Ti5O12 has a significantly higher experimental capacity than the most common capacitor material, activated carbon. The capacity remained high even at high discharge rates due to a successful nanostructuring that increased the accessibility of the material and shortened the diffusion distance for the ions, leading to a much improved power performance compared with the bulk material. The use of a nanostructured Li4Ti5O12 material in a hybrid device together with activated carbon was estimated to double the energy density compared to an electric double-layer capacitor and maintain the same good power performance. To further increase the energy density also improved materials for the positive electrode should be investigated.

Abstract:
A spray deposition manufacturing route has been developed for the fabrication of carbon nano-structured and micro-structured energy storage devices in a thin film format, with controlled film thickness, homogeneous film surface morphology and high electrochemical performance for both supercapacitors and lithium ion battery anodes. Three types of low cost commercially available carbon materials (graphite, activated carbon and carbon black) have been investigated, and electrodes characterised in terms of surface morphology, surface chemistry, microstructure and electrochemical properties. By using ball milling, CO2 activation and adding suitable carbon conductive additives, nano-graphite-based film electrodes (one meter long and ~ 3 µm thickness) have been fabricated, with excellent ion transport and low electrical resistance (< 1.8 Ω). Specific capacitance of 110 F/g at a scan rate of 100 mV/s in 1 M H2SO4 was achieved. The high rate performance of activated carbon-based electrodes ( ~2 µm thickness) has been enhanced by reducing the contact resistance of electrode/current collector interface and building a well-interconnected and hierachical meso/macro-porous structure. A specific capacitance of over 120 F/g at a scan rate of 600 mV/s or 20 A/g current density in 1 M H2SO4 was achieved. The performance of carbon black-based electrodes (~4 µm thickness) in different electrolytes has been studied in both two- and three-electrode cells. High specific capacitances of 260 F/g at 1 A/g was achieved in 6 M KOH, together with energy and power densities of 21 kW/kg and 18 Wh/kg in 1 M Na2SO4. Finally, graphite-based electrodes for rechargeable lithium-ion batteries have also been fabricated with controlled film thickness from ~ 900 nm to ~ 40 µm and 98% capacity retention of 371 mA/g after 20 cycles. Spray deposition has been demonstrated to have the potential for scalability in the manufacture of carbon-based thin film electrodes with competitive properties.

Abstract:
Supercapacitors have emerged in recent years as a promising energy storage technology. The main mechanism of energy storage is based on electrostatic separation of charges in a region at the electrode-electrolyte interface called double layer. Various electrode materials including carbon and conducting polymers have been used in supercapacitors. Also, supercapacitors offer high life cycle and high power density among electrochemical energy storage devices. Despite their interesting features, supercapacitors present some disadvantages that limit their competitivity with other storage devices in some applications. One of those drawbacks is high self-discharge or leakage. The leakage occurs when electrons cross the double layer to be involved in electrochemical reactions in the supercapacitor’s electrolyte. In this work, the first research project demonstrates that the addition of a very thin blocking layer to a supercapacitor electrode, can improve the energy storage capability of the device by reducing the leakage. However, the downside of adding a blocking layer is the reduction of the capacitance. A second project developed a mathematical model to study how the thickness of the blocking layer affects the capacitance and the energy density. The model combines electrochemical and quantum mechanical effects on the electrons transfer responsible of the leakage. Based on the model, a computational code is developed to simulate and study the self-discharge and the energy loss in hypothetical devices with different thicknesses of the blocking layer. The third research project identified the optimal amount of a surfactant (Triton-X 100) that had a significant effect on the double layer capacitance and conductivity of a spin-coated PEDOT:PSS (poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate)) electrode. The effect of the concentration of the surfactant was investigated by measuring the electrochemical properties and the conductivity of different electrodes. The electrodes were fabricated with different concentrations of the surfactant. Scanning electron microscopy characterizations confirmed the structural change in the PEDOT:PSS that contributed to the capacitance and conductivity enhancement. A final research project proposed an approach on how to utilize the modified PEDOT:PSS added to different photoactive dyes to design a photoactive supercapacitor. The new approach showed the possibility of using a supercapacitor device as an energy harvesting as well as a storage device.

Abstract:
The face of electricity generation, transmission and distribution is changing due to economic, technology and environmental incentives. Recently, interactive and intelligent electricity grid structures which consist of interconnected small/medium sized generators, power electronic technologies and energy storage elements have been developed to address the major shortcomings of the traditional electricity grid structure. Microgrids are key elements of these emerging grid structures. Although microgrids are accepted as possible solutions to power quality and power stability issues in ac power systems, the uncertainty in the ability of microgrids to cope with severe fluctuating load and fault conditions is a major concern in the operation of these new grid structures. This project was aimed at improving frequency control within a microgrid. Four objectives were identified and addressed to meet this aim. I. A weak microgrid network using an emulated internal combustion engine generator and associated loads was modelled. The emulation of a diesel generating set was achieved with a vector controlled induction motor driving a synchronous generator. The diesel engine emulation was achieved by incorporating a single delay into the speed control loop of the vector controlled induction motor. The modelled microgrid network is a very useful tool for the development of novel control schemes for frequency control within a microgrid. II. Simulation studies were carried out to investigate how a weak power system can be strengthened through the use of enhanced STATCOM and Supercapacitor energy storage. This assisted in understanding the limitations and performances of the novel algorithms proposed for frequency control improvement. III. Novel open and closed loop control algorithms for frequency control within a microgrid were proposed. The advantage of the open loop control scheme is its simplicity but the functionality of the control action is limited with the knowledge of the diesel engine transfer function and load current being important requirements. A closed loop control scheme was employed to address the limitations of the open loop control scheme. IV. A laboratory prototype of the microgrid network was developed and used in validating the novel control schemes proposed. The thesis describes the novel algorithms for frequency control using an intelligent STAtic COMpensator (STATCOM) and SuperCapacitor Energy Storage System (SCESS). The benefits and effectiveness of the proposed algorithms are given in the simulation and experimental results.

The work in this thesis focuses on the characterization, modeling and emulation of both the supercapacitor and the new supercapattery energy storage device. The characterization involves the selection of dynamic models and experimental methodologies to derive model parameters. The characterizing processes focus on predicting short-term device dynamics, energy retention (self-discharging) and losses and round-trip efficiency. A methodology involving a pulse current method is applied for the first time to identify a model parameter to give fast device dynamic characteristics and a new constant power cycling method is used for evaluating round-trip efficiency. Experimental results are shown for a number of supercapacitor and supercapattery devices and good results are obtained. The derived models from the characterization results are implemented into the emulator system and the emulator system is used to mimic the dynamic characteristics of a scaled-up 1kW supercapattery device. The thesis also addresses voltage equalizing circuits and reports a study that investigates efficiency, a cell voltage deviation and voltage equalizing time for different control methods.

Abstract:
This article will propose different energy storage systems, ranging from 0.91 kWh to 1.56 kWh, suitable for a 30 m long tram. To configure the system regarding energy content, voltage variation, maximum current and power losses, a model of the tram, network and substations power flow has been developed in a Matlab/Simulink environment. Results obtained in energy savings at substation level vary from 24% to 27, 6% under the same driving profile and auxiliaries load; while at the end-of-life of supercapacitors, the range varies from 18, 1% to 25, 1% depending on the supercapacitor module used and vehicle load.

Abstract:
An Electrical Heave Compensation System will cause large power demand fluctuations with a period time e.g. of around 8 to 12 seconds. These large power fluctuations are not desirable for the stability of the ship’s electrical power grid. This paper proposes the application and control of a supercapacitor based ESS in a power electronic system with a common DC Bus to limit the effect of the power fluctuations on the ship’s electrical power grid. The regenerated power from the heave compensation movements is temporarily stored in supercapacitors and used again when power is demanded. This causes a more constant power flow from the ship’s electrical power grid, which will cope with the losses in the system. Two topologies are discussed, namely the direct connection of the supercapacitors to the common DC bus and the indirect connection of the supercapacitors to the common DC bus through a DCDC converter. The result of the modelling and experiments of both ESS topologies shows that the high power fluctuations caused by an electrical heave compensation system are significantly decreased.
