Evaluation for Charging effects of Plug-in Electrical Vehicles in Power System considering Optimal Charging scenarios

전기자동차의 충전부하특성 모델링 및 충전 시나리오에 따른 계통평가

The impacts of EV charging demands on power system such as increased peak demands may be developed by means of modeling a stochastic distribution of charging and a demand dispatch calculation. Optimization processes are proposed to determine optimal demand distribution portions so that charging costs and demands can be managed optimally. There are two optimization methods which have different effects on the outcome. These focus either on the Electric vehicle customer side (cost optimization) or the System Operator side (Load-weighted optimization).
