A Method of Optimized Configuration of Integrated Energy System for Commercial and Residential Area

How to build the system configuration of regional integrated energy is crucial for its economic and stable operation, and it is extremely practical to carry out its research. Therefore, this paper builds the framework of integrated energy system and determines the main functional equipment, conversion equipment, transmission equipment and other equipment types of the commercial and residential integrated energy system, which mainly includes: CHP (Combined Heat and Power generation) module, gas turbine module, electric refrigeration module, absorption refrigeration module, electric power system module, heat system module, cold system, gas system module. CHP) module, gas turbine module, electric refrigeration module, absorption refrigeration module, electric power system module, heat system module, cold system, gas system module. The mathematical model of each module is clarified. With the goal of minimizing the operating cost and investment cost, and taking the regional energy supply and demand balance and the conversion characteristics of each equipment unit as constraints, the mathematical model was constructed. The NSGAII (Non-Dominated Sorting Genetic Algorithm II) algorithm was selected to solve the two-objective programming problem and solve the optimal allocation problem.
