ToU V2G 요금제를 이용한 운영에 따른 전력계통 영향 평가 = Evaluation of Power System Impact by V2G Operation Using Time-of-Use Tariff

다국어 초록 (Multilingual Abstract)

This study evaluates the impact of the power system on the continuous increase of electric vehicles(EV) and presents a plan to reduce the peak load of the power system and increase the stability of the system through the introduction of the V2G system and the introduction of the Time-of-Use tariff using a simulated power system consisting of 17 buses. Based on the charging load of EVs through the current EV's unidirectional charging system, we analyze the expected charging load from the introduction of the V2G system and the expected charging load from the introduction of the Time-of-Use tariff. In the model in which the ToU tariff was introduced, the change in charging demand due to changes in charging costs was estimated using price elasticity. In this study, through the introduction of the V2G system and the introduction of the ToU tariff, the step-by-step power system stability increase effect can be expected and the appropriate introduction time of each model can be estimated based on the voltage stability
