Operation optimization of power and natural gas integrated energy system based on multi-objective optimization

In order to improve the operation capability of the integrated energy system, an operation Evaluation of the integrated power and natural gas system based on multi-objective optimization is proposed. An electrical-pneumatic coupling system is established, and the operating characteristics and composition of the system are described. A model is established for the operation optimization of a comprehensive system including natural gas, considering the impact of cost and emissions, and modeling and analysis from the perspective of power system constraints, natural gas system constraints, and coupling system constraints. The solution is carried out using the multi-objective particle swarm method. Simulation analysis shows the effectiveness of the proposed method.
