Assessing The Flexibility From Electric Vehicles To Facilitate Renewable Integration

The integration of electric vehicles and other distributed energy resources into power systems is becoming more common,presenting significant challenges to distribution grids during peak load periods and raising issues regarding grid balancing.To avoid investing in costly solutions,power systems require enhanced flexibility,and one solution is to use electric vehicles as an electricity source,known as Vehicle to Grid(V2G).Electric vehicles can support both G2V and V2G modes and offer features such as regulating active power,supporting reactive power,peak load shaving,and frequency regulation.The penetration of renewable energy sources(RES)such as wind and solar energy is also increasing,but these sources are intermittent and pose challenges such as power quality issues and voltage and frequency fluctuations.EVs in V2G mode can act as a flexible source to meet these challenges and provide ancillary services such as frequency regulation and peak load shaving.This thesis systematically identifies key aspects for proactively integrating EVs into electricity grids as providers of flexibility services to facilitate renewable integration.A framework for exploiting the flexibility potential of EVs,including V2G mode,to facilitate renewable integration is presented.The results show that the power generated from all sources meets the peak load demand for 24 hours.
