In view of the consumption problems of renewable energy such as wind power and photovoltaics,and the multiple energy needs of users,the specific application of integrated energy systems involving multiple energy forms in the park microgrid is studied to operate the system economy and energy.Efficiency is the goal,and the optimization configuration of various micro-sources and energy flow topologies in the micro-network of the park is studied.Based on this,the energy-optimized scheduling strategy for the integrated energy micro-grid operation conditions is studied.This paper first introduces the typical physical architecture of the integrated energy system.According to the multi-energy coupling characteristics of the system,a multi-level energy hub model is established.According to the different energy equipment conversion characteristics in the system,the equipment in the integrated energy system is divided into energy transmission equipment.Energy conversi on equipment and energy storage equipment,and established corresponding equipment models.In order to effectively describe the internal energy optimization management problem of the integrated energy system containing multiple energy production and supply,the comprehensive energy system benefit evaluation index is established,and the comprehensive energy system benefits are evaluated from three aspects: economy,environment and efficiency.The load is subdivided in the form of multiple energy sources in a typical integrated energy microgrid,and the optimal configuration principle of the park microgrid is determined.The park microgrid optimization scheduling model and the park microgrid optimization configuration strategy together constitute a two-layer optimal configuration model of the park microgrid.Using the typical cold-cold heat load of the park micro-grid in summer,winter and transition seasons,and the wind-power simulation curve of the wind turbine under three seasons,the optimal configuration scheme of the micro-grid is obtained,and in this scenario,the area is summer.The typical day operation scheduling scheme analyzes and verifies the effectiveness of the microgrid optimization scheduling model.
