A Study on Daily Operation Model for Total Energy System Including Building Cogeneration, Ice Storage, Thermal and Electrical Storage Facilities

건물용 열병합발전 설비를 중심으로 한 종합 에너지 시스템의 최적 일간 운전모형 수립에 관한 연구

In this paper, we propose an optimal daily operation model for the total energy system which includes cogeneration, thermal storage and electrical charger and ice storage facilities. Storing and utilizing the surplus thermal and electrical energy, the daily operation cost could be reduced and more efficient use of thermal energy could be achieved. The ice storage cooling system has a merit of reduce the electricity cost by time of day rate(peak/off-peak). And also, refrigerator can be down sized compare to the other cooling system From this model, operation costs of the sample cogeneration system with/without auxiliary facilities are obtained and compared to each other. In case study, the sensitivity of operating cost is simulated according to the variation of cogeneration production cost, electricity rate, etc.
