Abstract

With the continuous development of economy and society, under the double pressure of energy shortage and environmental pollution, the comprehensive energy system combining wind energy, solar energy, sewage and other energy sources has developed rapidly and been widely used. In order to alleviate water pollution and energy shortage, this paper studies the planning and optimization of comprehensive energy system considering sewage reuse. Firstly, based on the potential of urban sewage reuse, the typical structure of energy system for sewage reuse is constructed. Secondly, aiming at minimizing the economic cost of the system, taking the lowest purchased energy cost and operating cost of the urban comprehensive energy system into consideration, and considering the power balance constraints of the comprehensive energy system, an optimization model of urban comprehensive energy system planning with wastewater reuse is established. Finally, the energy and sewage data of a city are selected for verification in a multi-energy system coupled by an improved IEEE24- node distribution system and an eight-point heat pipe network. The results show that the total planning cost of the urban comprehensive energy system planning optimization model with sewage reuse is reduced by 27.23% in the planning period, and the capital recovery period is increased by 1.2 years compared with that before use.
