Research on the Construction Model of Hydrogen-Electric Integrated Energy Stations in Typical Climate Regions of China

Abstract

The hydrogen-electric integrated energy station will play an important role in the new power system with renewable energy as the main body. This paper establishes an optimization model for the system configuration of a hydrogen-electricity integrated energy station, further explores the differences in optimal configuration and operation modes of different station construction modes with different basic conditions in different places, and discusses the reasons. The research shows that the economy of the grid-connected mode is the best, and the economy of the off-grid mode is the worst. The local electricity price policy, wind and solar resource endowment, and stability will significantly impact the integrated energy station. At the same time, in the regions where the wind and solar resources fluctuate greatly from month to month, hydrogen can play the role of long-term energy storage.
