Simulation study demonstrates coordinated control of electric vehicles and reused batteries for emergency power distribution, indicating lower capital costs for regional microgrids.
The concept of a regional microgrid (MG) is to evolve a part of the existing distribution system into an MG, together with regional renewable energy resources available close to the demand area. One of the difficulties of a regional MG is its expensive capital cost, especially paid for larger facility capacities required for rare emergency situations such as natural disasters. This paper introduces an MG model that utilizes the existing power distribution lines for daily power supply and electric vehicles (EVs) as virtual distribution lines during emergencies. By using EVs for emergencies, the investment cost would be saved. This paper proposes a coordinated control scheme for EVs, which have different capacities, and reused batteries for supply and demand balancing during an emergency and demonstrates how the proposed control scheme realizes the virtual distribution line function by EVs.
