초록

본 논문은 PSO 알고리즘을 이용하여 물 재이용 펌프 시스템의 에너지비용을 최소화 할 수 있는 방법을 제안한다. 1시간 단위의 시간대에서 펌프제어를 위해 계시별 요금제를 기반으로 하여 최적화 구간을 설정하고 PSO알고리즘을 이용하여 에너지 비용을 절감할 수 있도록 펌프동작을 제어한다. 물 재이용 펌프시스템에서 고정된 유량을 출력하는 펌프와 입력전력을 가변할 수 있는 펌프에 대해 TOU 기반에서 에너지 비용을 최대로 줄일 수 있도록 시스템을 동작시킨다. 시뮬레이션을 통해 제안한 에너지 비용 절감 방법이 기존 수위기반의 제어방법보다 비용을 절감할 수 있음을 확인할 수 있다.

This paper presents a control method for energy cost saving in the water reuse pumping system. An optimize horizon switching strategy is proposed to implement an pump control. And Particle Swarm Optimization (PSO) algorithm is used to solve optimal problems in each time step. Energy costs are calculated for electricity on both TOU in the light, heavy, and maximum load time period and peak charges. The control method in water reuse pumping systems is determined to reduce the TOU cost. The simulation results show a energy cost saving for water reuse pumping systems.
