Abstract

Abstract:

Integrated community energy system (ICES) can make full use of renewable energy and improve the energy efficiency of ICES. This paper focuses on the optimal dispatching problem of ICES. Firstly, we construct the optimal dispatching model of ICES with electricity as the core, whose optimization objectives include the economic optimum criterion and the environmental optimum criterion. Based on the typical equipment models of renewable energy technique, energy-saving technique and power substitution technique, the operation constraint model and demand balancing constraint model on electrical and cool/heat are established for the periods of heating and cooling respectively. Particle swarm optimization (PSO) algorithm with good global search capacity is applied to solve the optimal dispatching problem. The model and the algorithm are verified through a case study to produce optimal dispatching plans of ICES under the economic and environmental criterion respectively. Meanwhile, the reasons of the similarity and contradiction in the dispatching plans under different objectives are compared and analyzed.

Key words: integrated community energy system (ICES), multi-objective, optimal dispatching, particle swarm optimization（PSO）
