Abstract: In recent years, worldwide energy consumption has been increasing. Therefore, it is very important to improve energy utilization efficiency. Theelectric energy and heat energy can be converted from fuel by the combined cooling, heatand power (CCHP)system and the energy utilization efficiencycan be improved by the system.This project mainly studies the optimized operation of microgrid based on CCHP system. In this project, the micro gas turbine, fuel cell, electric boilerand etc. are belong to controllable units in themulti-energy micro grid system,thewind turbine, photovoltaiccell, electrical and thermal energy storage systemsare belong to uncontrolled units.The optimization model in this paper aims at the lowest total cost of operation of the system and needs to satisfy the power balance of thermal energy and electric energy. The constraints include the relative constraints of each device in the system and the relative constraints of the system. In the meantime, scheduling flexibility also needs to be guaranteed. The model is treated as mixed integer linear programming(MILP)problem and solved efficiently by YALMIP.A real system is used for simulation analysis. Compare the three modes to study the efficiency of the model. Simulation results show the effectiveness of the model and algorithm.
