Multi-Objective Optimization of Regional Power and Natural Gas System in Coordination with Park Level Cooling and Heating System

The operation optimization of multi-heterogeneous energy system (MHE) is the key to improve energy efficiency. This paper studies the economic and emission components and establishes a multi-objective optimization model. The regional power system, natural gas system and park level cold heat system are modeled respectively to build a multi heterogeneous energy system network architecture to meet the actual application needs. The multi-objective optimization method of MHE system based on NSGA-II algorithm is studied to realize the optimization solution of economy and emission. Through the simulation analysis of the experimental case, the optimal solution set is provided for the decision-maker quickly and effectively.
