In this regard, the behaviour of a hybrid energy storage unit consisting of battery storage and a supercapacitor is examined. The battery storage is designed to meet the energy requirement of the system while the supercapacitor is used to respond to rapid power fluctuations of the RAPS system. The battery storage is connected to the AC side of the system through an inverter while the supercapacitor is connected to the DC link of the back-to-back converter system of the DFIG via a two stage bi-directional buck boost converter. A control strategy is adopted for the hybrid energy storage system in which the operation of the battery is limited to a lower Depth of Discharge (DOD). The dump load is used to absorb excess energy in the system which cannot be utilised by the energy storage system. The entire RAPS system has been modelled using MATLAB Simulink.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125377976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed system is based on series inverter with capacitor banks in each phase. The main advantage of this method is fast response to eliminate resonance. Another advantage is the use of a low gain proportional controller, rather than a PI controller, to control the dc link voltage. It is shown that P controller improves the transient response of the system to the load changes. Also, THD of voltage at the point of common coupling and the capacitor bank current is significantly reduced.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125218044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regarding this as an international trend, it is relevant to study this issue on the world-wide scale. This study focuses on the development of a simulation technique based on linear optimization to study the impacts of large-scale integration of intermittent renewable energy sources into the electricity supply system at world-wide scale. The model has been examined versus actual data and calibrated through an iterative process. The model is then applied to study the economical and environmental impacts of wind power on the electricity generation system. Regarding the dependencies of the resulting effects on the design of the base electricity system, penetration share of wind power as well as exogenous parameters, sensitivity analyses on these factors have been performed. The influential role of international exchange as a solution option for large-scale integration of wind power is studied further.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122469459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With industrial inductive loads, the utility grid has not only to supply their reactive power needs, but also to supply extra reactive power to compensate for the expected power factor deterioration caused by DG active power injection. Among various DG options, Fuel cell technology makes a clean, highly controllable and economically viable DG option. Local reactive power compensation is a particular feature of fuel cell systems, as they will always be very close to the point of usage of electricity. With smart control algorithm of the grid coupling inverter, it is possible to enable reactive power management of the fuel cell DG system. This paper presents a smart control algorithm of the fuel cell DG grid coupling inverter, which provides active/reactive power management capability for the DG unit. The controller modeling and performance validation is performed at a test system, for a proposed operation scenario using Matlab/Simulink and Simpower system blocks. This validation proves the capability of using the proposed controller for power factor improvement.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"438 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122789551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, the capacitors have high power capability and they can hence only be considered for applications which require little energy. There was thus a lack, in means of storage energy for high power applications, between the batteries and capacitors that supercapacitors (SCs) try to minimize. This paper deals with the conception of an embedded power source using supercapacitors which are charged by means of Unit Power Factor (UPF) electronic converter. These supercapacitors ensure the power supply of an electrical network miniature rail of 150W by using sliding mode principle control. The operating principle of this device and some simulation results obtained under Saber software and experimental results are presented.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128083819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We can expect that more 60 % of all energy consumption will be converted and used as electricity. It is a demand that production, distribution and use of electrical energy are done as efficient as possible. Further, emerging climate changes argues to find future solutions which also are sustainable. Two major technologies will play important roles to solve parts of those future problems. One is the change the electrical power production from conventional, fossil (and short term) based energy sources to renewable energy sources. Another is to use high efficient power electronics in power generation, power transmission/distribution and end-user application. This paper discuss trends of the most emerging renewable energy sources, wind energy, which by means of power electronics is changing the future electrical infrastructure but also contributes steadily more to non-carbon based electricity production.

This is why the main focus of recent research activities is on minimizing or totally displacing diesel based generation by using hybrid power systems combining wind turbines, solar photovoltaic systems, storage devices and fuel cells. For large rural grids, finding the right place to connect the solar photovoltaic systems must be strategic and optimized.

The conventional line commutated ac-to-dc inverters have square-shaped line current which contains higher-order harmonics. The line current with the high harmonic contents generates EMI and moreover it causes more heating of the core of distribution/ power transformers. Alternatively, PWM based inverters using MOSFET/IGBT switches are also used for the same purpose. However, apart from higher switching losses, the power handling capability and reliability of these devices are quite low in comparison to thyristors/ SCR. Nevertheless, the conventional thyristor based forced commutated inverters are not suitable for PWM applications due to the problems of commutation circuits. A pure sinusoidal line current or waveform with low harmonic contents is the most desirable for grid tie inverters. In the present work, various multilevel line commutated inverter topologies has been proposed and analyzed which improves the wave shape and hence reduces the total harmonic distortion (THD) of the line current in a grid tie line commutated inverter. The scheme has successfully been implemented and tested. Moreover, the performance of the proposed topology is far better than the conventional line-commutated inverter. It reduces THD, losses, switching stress and EMI.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116087231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
