Modelling for Optimal Load Dispatch of Integrated Renewable Energy Source/BESS/Electric Vehicle Charging Station

To enhance the utilization of renewable energy resources, to fulfill the increased demand of energy and to reduce global warming and degradation of ecosystem, the economic load dispatch of an integrated system considering renewable energy source (RES), electric vehicle load/ charging station (EVL) and battery energy storage system (BESS) has been planned across the world. The main aim of economic load dispatch in power system operation is to fulfill the energy load demand at the most economic cost while achieving all the equality and inequality constraints. This paper presents the mathematical formulation of optimal load dispatch problem by considering the sources of energy generation from conventional power plants and renewable energy sources with electric vehicles (plug-in, PEVs and battery, BEVs). The power from the standby electric vehicles can be used as a reserve for ancillary services that can be utilized as spinning reserve.
