Research on Power Storage Optimization Operation Strategy for Wind-Photovoltaic Power Coupled Hydrogen Production

Abstract

Under the guidance of the “double carbon” development goal, new production and marketing methods of green energy, such as wind-photovoltaic coupling hydrogen production, are developing rapidly. Due to the lack of engineering experience, there is still a lack of corresponding strategies for capacity allocation and operation control of renewable energy coupled hydrogen production. Moreover, due to the strong volatility of landscape resources and the flexible adjustment ability of hydrogen production load, the accumulation of uncertainties at both source and charge will further affect the stability of system operation. Therefore, this paper first focuses on the scenario of a microgrid with wind-photovoltaic coupled hydrogen production, comprehensively considers the uncertainty factors of green hydrogen production, and takes economic optimization as the goal to construct an operation optimization typing model of microgrid based on energy storage. Secondly, the microgrid makes full use of the flexible characteristics of energy storage to balance the power supply and demand in the microgrid and to reduce the impact of the fluctuations of the distributed energy system on the grid. Then through the demonstration and analysis of specific examples, the configuration and operation strategy of the system power storage under the differential influence factors are obtained.
