Solving the volatility and intermittency of renewable energy output in the power system is the key to ensure the normal operation of the microgrid.An optimization model of wind and photovoltaic complementary power generation to hydrogen storage system with the coordination of economy and energy consumption is proposed in this paper.Considering the application of electrolytic water hydrogen production device in the energy system,taking the system operation cost and renewable energy consumption ratio as the optimization objectives,the effectiveness of the model is verified by using multi-objective optimization algorithm,and the important role of wind and Photovoltaic power(PV)generation hydrogen production device in optimizing the economic operation of the system and improving the wind power and PV energy consumption is compared and analyzed by controlling start and stop of the electric hydrogen production device in the system,and this study provides a new ideas and solutions to effectively solve the problem of“abandoned wind and abandoned light”.
