综合能源系统的运行优化配置分析

Study on the operation and optimal allocation of comprehensive energy system

综合能源系统中,不同能源之间的相互转换可提高能源的利用效率,是区域综合能源系统规划的重要研究课题。就综合能源系统的结构而言,研究了冷热电联供系统(Combined Cooling Heat and Power,CCHP)、电转气装置(Power to Gas,P2G)、储气装置、热电联产机组(CHP)和太阳能光伏发电机组等设备互补协同作用下的成本。讨论了不同配置系统的经济性和可行性,建立了一系列模型,并且用粒子群算法进行求解。算例结果表明,配置蓄冷和储热模型在能源互联网系统中可以增加收益,同时能源的相互转化在一定程度上可以提高能源利用率,减少环境污染。

In the integrated energy system,the mutual conversion between different energy sources can improve the efficiency of energy utilization,which is an important research topic of regional integrated energy system planning.This paper studies the cost of CCHP,P2 G,CHP,solar photovoltaic generating units and other equipment under the complementary and synergistic effect.economy and feasibility of different configuration systems are discussed and particle swarm optimization and genetic algorithm are used to solve the problem after a series of models are established.The results of the calculation example show that the configuration of cold storage and heat storage models can increase revenue in the energy Internet system,and the mutual conversion of energy can improve energy utilization to a certain extent and reduce environmental pollution.
