Wind Energy Penetration with Load Shifting from the System Well-being Viewpoint

Abstract

Due to the pollution of the traditional power generation resources and environmental problems, development of power generation resources has become a major problem in today's world. Because of this reason and economic reasons for fossil fuels, the electricity industry designers and policy-makers are to provide solutions to improve the current situation and to reduce destructive environmental effects. In the meantime, the use of renewable resources such as wind and solar power plants has been a priority of many governments and companies. Because of the uncertainty of the renewable energy resources and their dependence on weather conditions, their influence is along with some problems including the loss of system reliability and reduced power quality. In this regard, demand management and reduced usage in the peak hours and shifting some consumption to low load hours can play a crucial role with respect to the renewable energy influence in the system. The potential demand and load management can play a role in either sides of consumption or generation of the electrical systems in order to reduce costs for consumers and manufacturers. With regard to different behaviors of loads in different sectors over their consumption time, seven different sectors of loads including domestic, industrial, large, commercial, administrative, governmental and agricultural loads are investigated in this paper as load shift and its impact on Well Being and on increasing the system reliability under different scenarios through wind energy. Well Being with sequential Monte Carlo method with/without the fuzzy logic is used for comparison. IEEE-RTS test system is selected to be examined in this study.
