Optimal Dispatch of Coal-Wind-Hydrogen Integrated System Considering Wind Power Uncertainty

The randomness of wind power output leads to a very weak absorption capacity, and there is a serious phenomenon of wind abandonment. The construction of transferable new energy consumption equipment is a possible solution. This paper proposes an optimal dispatch strategy for a coal-wind-hydrogen integrated energy system considering new energy consumption equipment. Wind power uncertainty is described using nonparametric kernel density estimation (KDE). On this basis, shortterm dispatch economic optimization is carried out with the goal of maximizing the overall benefit of the composite coal-windhydrogen integrated energy system that produces electricity and hydrogen. The simulation results show that when considering hydrogen energy storage, the phenomenon of wind curtailment is significantly improved, which improves the operating economy of conventional units and storage equipment, and improves the economy of system operation while ensuring the new energy storage capacity. This paper provides a new perspective for the formulation of economic operation strategy of coal-windhydrogen integrated energy system including wind farms and hydrogen production equipment.
