摘　　要：在区域能源互联网大力推进、绿色低碳经济大力发展和多能流耦合度不断增高的背景下,如何提高微能源网的经济稳定性,实现其运行优化已成为研究热点。然而空调负荷的日渐增长给微能源网的经济运行带来了挑战。为此引入热泵和相变储能,以缓解用能紧张,提高能源利用效率和系统的灵活性。综合考虑热泵的出力特性和相变储能的储能特性,提出了一种多能互补微能源网运行优化模型。为分析模型的经济节能性,在分时电价和并网运行条件下,以全寿命周期成本最低为目标函数,采用混合整数规划法进行求解。仿真结果表明,引入热泵和相变储能能够减少空调负荷耗能,降低系统运行成本,具有较好的灵活性和经济性。With a background of the vigorous promotion of the regional energy internet,vigorous development of a green and low-carbon economy,and the increasing coupling of multiple energy flows,how to improve the economic stability of the micro-energy network and optimize its operation has become a hot research topic.However,the increasing load of air-conditioning has brought challenges to the economic operation of the micro-energy network.To this end,heat pumps and phase-change energy storage are introduced to alleviate energy shortages,improve energy efficiency and system flexibility.Considering the output characteristics of the heat pump and the energy storage characteristics of the phase change energy storage,an operational optimization model of a multi-energy complementary micro-energy network is proposed.To analyze the economic and energy-saving effect of the model,under the conditions of time-of-use electricity price and grid-connected operation,with the lowest life cycle cost as the objective function,the method of mixed integer programming is used to solve the model.Simulation results indicate that the introduction of heat pumps and phase change energy storage can reduce both air conditioning load energy consumption and system operating costs,and has better flexibility and economy.
