Abstract

The electricity demand and supply could be off balance if several electric vehicles(EVs) were charged at the same time or at peak load times. Therefore, smart grids are necessary to flatten the EVs' electricity demand and to enable EVs to be used as distributed storage devices as electricity demand from EV-charging increases. There are still few quantitative studies on the impact of smart grids on managing EVs' electrical loads. In this study, we analyzed the quantitative impact of smart grids on managing EVs' electrical loads and suggested policy implications. As a result, it is identified that smart grids can manage effectively EVs' impact on electrical grids. The electricity market structure and regulatory framework should support the demonstration and commercialization of smart grid technologies.

전기자동차 보급이 확대됨과 동시에 충전이 특정 시간대에 몰리거나 전력수요가 높은 시간대에 늘어나면 전력수급 균형이 불안해질 수 있다. 따라서 전기자동차 충전으로 인한 전력수요가 증가함과 동시에, 전기자동차의 전력수요를 분산시키고, 전기자동차 배터리의 여분의 전기를 활용할 수 있는 스마트그리드 구축이 중요해진다. 아직 국내에서 스마트그리드가 전기자동차의 전력망 영향 관리에 어느 정도 영향을 미치는지에 대해서는 정량적 연구가 미흡한 실정이다. 본 연구는 스마트그리드를 통한 전기자동차의 전력망 영향 관리 효과를 정량적으로 분석하고 정책적 시사점을 제시하였다. 결과적으로 스마트그리드는 전기자동차의 전력망 영향을 효과적으로 관리할 수 있었다. 전력시장 구조와 규제 프레임워크는 스마트그리드 기술의 실증과 상용화 촉진을 뒷받침할 수 있어야 할 것이다.
