Abstract

In this paper, we had developed an algorithm that can cope with all the economic variables that may occur in the operation of PV-ESS system by developing the algorithm for the operation method of PV-ESS connected system. Based on this, the optimal operation schedule of PV-ESS was decided to minimize the electric charges of customers. Through this, we developed a three-dimensional dynamic planning method based on case generation to determine the optimal PV-ESS operation schedule stably even when exogenous variables change.

본 논문에서는 PV-ESS 연계형 시스템의 운용방법에 대한 알고리즘의 개발로 수용가의 경제성 측면에서 PV-ESS 시스템 운용 시 발생할 수 있는 모든 경제적 변수의 변화에 대처할 수 있는 강인한 알고리즘을 구현하였다. 이를 토대로 수용가의 전기요금을 최소화 할 수 있는 PV-ESS의 최적 운용 스케줄을 결정하였다. 즉, PV-ESS 시스템의 운용에 영향을 주는 외생 변수가 바뀌어도 항상 안정적으로 최적의 PV-ESS 운용 스케줄을 결정할 수 있으며 이를 위하여 케이스 생성 기반 3차원 동적 계획법을 개발하였다.
