Abstract:The heating/cooling and power supply strategies of integrated energy system are proposed considering the peak valley price spread arbitrage of TOU electricity price of energy storage system, which are used as the inner simulation optimization kernel of economic allocation model. A double layer programming model of integrated energy system is established based on the whole life cycle theory and strategic simulation optimization kernel. The outer layer takes into account the economic and environmental benefits of the integrated energy system and minimizes the total annual planning cost of the system as the optimization goal. The inner optimization model adopts the annual simulation time domain (8760 h) to enhance the matching characteristics between the generation output of power supply side and the load of energy consumption side, so as to improve the effectiveness and economy of the configuration results. The enhanced elite retention genetic algorithm is used to call the inner simulation optimization kernel to simulate and solve the two layer configuration model. An example analysis verifies the effectiveness of the proposed strategic economic allocation method for integrated energy systems, and discusses the critical peak valley price spread suitable for arbitrage of energy storage systems, which can provide reference for the related engineering projects in the early stage of project analysis.
