An Optimization Method for Operating Schedule of District Heating and Cooling Plant

Abstract

This paper presents an optimization methodology for operating schedule of DHC (district heating and cooling) plants. The optimization models are constructed by input-output properties of the components into a mixed 0-1 linear programming problem. The advanced features of the method are dealing with 1) double-bundle heat pumps, 2) thermal storage tanks, and 3) peak-cut strategy. The computer simulation shows that the optimization results based on the method are an appropriate schedule for the DHC plant operation.
