Energy Optimization Management Strategy of Photovoltaic Hydrogen Production System Based on Stackelberg Game

In allusion to the problem that it is difficult to meet the growing demand for hydrogen energy due to the low economy of hydrogen energy production, an energy optimization management strategy model for a photovoltaic hydrogen production system based on the Stackelberg game mechanism was proposed. Firstly, in the game model, the hydrogen energy producer, as the upper leader, set the hydrogen energy price traded with the lower users with the goal of maximizing the net income; As the follower of the lower layer, the users adjusted their energy consumption strategy and fed the required load back to the upper layer with the goal of maximizing consumer surplus and taking into account the hydrogen selling price set by the hydrogen energy producer of the upper layer. The two sides play a game and finally reach the game equilibrium. Secondly, the energy management mode of the photovoltaic hydrogen production system was established to optimize the output of each piece of equipment of the hydrogen production system to achieve the goal of improving the economy of hydrogen energy manufacturers and meeting the hydrogen energy demand of users. Finally, by analyzing the game objectives and strategies of hydrogen producers and users, a unique equilibrium solution in the game being exist was proved theoretically, which the model was solved by calling the Cplex, The results show that the proposed game model can effectively improve the system economy and meet the needs of users, and achieve a win-win effect for both players.
