초록

본 논문은 연료비를 최소화 할 수 있는 2차전지 전력저장장치(BESS: Battery Energy Storage System)와 풍력-디젤 복합발전시스템으로 구성되는 독립형 마이크로그리드을 모델링하는 방법과 그 운전제어 알고리즘을 제안하였다. 먼저, 부하변동 및 풍속변동에 따른 주파수와 전압을 일정하게 제어할 수 있는 양방향 DC/AC 컨버터의 BESS를 모델링하고, 디젤발전기는 공급전력의 부족 및 BESS의 충전시에만 가동하도록 하는 운전제어알고리즘을 제안한다. 그리고, 제안된 모델링 방법과 운전제어알고리즘을 독립형 마이크로그리드에 적용한 결과, 풍속 및 부하변화에 대하여 주파수와 전압변동이 적정범위내로 유지할 수 있음을 증명할 수 있었다.

This paper proposes a modeling method and operating algorithm of an islanding microgrid that is composed of a Battery Energy Storage System (BESS), wind turbine and diesel generator applied in island areas. Initially, the bilateral AC/DC converter was designed for charge/discharge for frequency and voltage to be maintained within the proper ranges according to the load and weather change, and the operating method was proposed for a diesel generator to operate when power supply from the wind turbine or BESS is insufficient. The proposed modeling and controller design method of BESS was applied to a typical islanded microgrid with a wind turbine and diesel generator. The frequency and voltage was kept within the permissible ranges and the proposed method was proven to be appropriate through simulations.
