국제적으로 에너지 소비량 증가로 인한 온실가스를 감축을 위해 노력하고, 화석연료의 의존도를 낮추기 위해서 기존시설의 효율 향상 및 신재생에너지원의 이용을 늘려가고 있다. 수송 분야에서는 배터리를 기반으로한 하이브리드 기법을 도입하여 내연기관의 효율성을 개선하고 있다. 또한 하이브리드 차량의 한계점을 극복하고 좀 더 효율적인 주행을 위하여 전력을 외부로부터 이용할 수 있는 PHEV(Plug-in Hybrid Electric Vehicles)가 상용화 되고 있다. PHEV의 보급으로 인해서 미래의 전력계통에서 잠재적인 전력수요를 유발한다. 이러한 전기자동차의 충전은 자동차의 운행패턴에 따른 충전방법에 따라 시간별 부하량이 달라지므로 본 논문에서는 세 가지 충전 시나리오를 작성하여 전기자동차의 보급에 따른 전력시장 가격에 미치는 영향을 분석한다. 2020년의 미래의 계통을 가정하여 시나리오를 적용하였다.

세계적으로 온실가스 감축을 위한 연비와 배기가스 규제로 인해 대부분의 선진국들은 전기자동차의 보급을 위해 파격적인 보조금과 세제 혜택을 내놓고 있다. 이러한 추세로 인해 전 세계적으로 전기자동차의 확산은 불가피할 것으로 전망된다. 전기자동차의 확산과 진화는 자동차 산업은 물론 관련 산업 전반에 새로운 변화를 예고하고 있다. 전력산업의 경우 전기자동차의 보급으로 인해 미래의 전력계통에 잠재적인 전력수요를 유발한다. 전기자동차의 충전은 자동차의 운행패턴에 따라 총전패턴이 결정되며 이로 인해 충전 부하량이 산정된다. 본 논문에서는 전기자동차의 보급전망 및 세 가지의 충전 시나리오를 이용하여 2020년 계절별(하계, 동계) 전력수요의 영향을 분석한다.
