Abstract

Currently used DLC(Direct Load Control) algorithm is only focused on ON/OFF load control not concerning about reliving participated customer's inconvenience and load priority. Therefore, that is a major obstacle to attract customer participating in demand response program. To overcome the above defects, the authors represent direct load control algorithm using priority based dynamic programming. the proposed algorithm is that participant customer send E-mail to DLC center about priority of load before executing DLC, then DLC algorithm decide which load to be OFF by using priority and off time constraint of the load. By using dynamic programming based on the order of priority for DLC algorithm it is possible to maximize participating customer's satisfaction and it will help to attract more customer's participating in demand response program.

현재 운용되고 있는 직접부하제어 알고리즘은 직접부하제어 사업에 참여에 따른 수용가의 개별 부하별 우선순위가 고려되지 않고 있고, 또한 제어 시간도 수용가의 불편을 고려되지 않고 획일적으로 일정 시간대에 일률적으로 수용가의 부하를 제어함으로써 참여 수용가의 불편 증대로 참여율이 저조한 실정이다. 따라서 본 연구에서는 참여 수용가의 불편을 최소화시키고 또한 개별 부하에 대한 우선순위 요구를 최대한으로 반영하기 위해 우선순위 기반 동적 프로그래밍을 이용한 직접부하제어 알고리즘을 제시한다. 제시되는 알고리즘은 직접부하제어가 발생되기 1시간 전에 참여 수용가가 스스로 해당 부하의 우선순위를 결정하여 직접부하제어 센터로 I-Mail 등으로 보네면 센터에서는 현재 부하의 전력량과 우선순위 그리고 OFF주기 등을 고려하여 동적 프로그래밍을 수행하여 OFF되어야 할 부하들을 선택하게 된다.
