In recent years, large-scale distributed power sources have been connected to the power system, resulting in problems such as node voltage crossing, power flow reversal, and increased network loss. In this regard, this paper proposes a voltage optimization strategy based on hydrogen storage equipment and photovoltaic power supply. Firstly, the influence of PV to the grid on the voltage quality of the grid is analyzed. Then, the hydrogen storage equipment and photovoltaic power supply are introduced to participate in the optimal regulation, and the voltage optimization model based on hydrogen storage equipment and photovoltaic power supply is established. Secondly, the voltage optimization model of distribution network is transformed into a convex optimization model, which is solved by Cplex solver. Finally, the effectiveness of the strategy is verified by the IEEE 33-bus system.
