Abstract:

Aiming at the problems of low energy utilization rate and serious waste of wind power in the complex energy systems in the industrial parks, an operation optimization method of wind-solar-hydrogen-storage integrated energy system considering electricity-gas bidirectional coupling is proposed.Firstly, an integrated energy system model of industrial park considering electricity-gas bidirectional coupling is established.Secondly, a multi-objective function is established with the total cost of the system, operating energy efficiency, carbon emissions, etc., as the optimization objectives, and the constraints such as equipment, tie lines, and power balance are considered.Finally, the Pareto frontier is used to transform the multi-objective problem into a single-objective problem, and the dynamic differential evolution algorithm is used to calculate and analyze the three operation modes of the industrial park.The simulation results show that the proposed method effectively promotes the wind power consumption in the industrial park, improves the comprehensive energy utilization efficiency of the park,enhances the environmental protection property and flexibility of the system operation, and reduces the total cost of the system operation.

Key words: electricity-gas bidirectional coupling system, integrated energy system (IES), Pareto frontier, differential evolution algorithm, power to gas (P2G), combined cooling heating and power (CCHP)
