Abstract

In this study, optimal operation strategies to save the electric energy and power price in the building central cooling system is researched by experiments. The optimal strategies of demand response control and outdoor temperature reset control algorithms are applied by consideration the electric energy and power price according to the energy consumption characteristics. The suggested optimal control method shows better responses in the power price and energy consumption in comparison with the conventional one and saves energy consumption by 9.5% and electronic price by 15.7%, respectively.

본 연구에서는 중앙냉방시스템용 모형실험장치를 구성하여 에너지 소비량 및 전력사용요금의 절감을 위한 최적제어방법을 구현하여 실험적 연구를 수행하였다. 최적제어방법으로는 새벽시간의 예냉을 이용한 전력디맨드 응답제어와 외기온도변화를 고려한 외기보상제어방법 등을 고려하였으며, 제어알고리즘은 LabVIEW 프로그램을 이용하여 작성하였으며, 제어 및 모니터링을 통해 최적제어방법과 기존제어방법과의 제어성능을 비교 고찰하였다. 연구결과로서 본 연구에서 제시한 최적제어방법이 기존제어방법에 비해 양호한 응답특성을 나타냈으며, 에너지소비량은 약 9.5%, 전력요금은 약 15.7%를 각각 절감한 것으로 나타났다.
