Outline
Aiming at the problems of high investment cost，low efficiency of electrolyzer operation and high fluctuation of power input in the new energy electrolytic water to hydrogen microgrid system，the scenery hydrogen production capacity configuration scheme with the installation cost of microgrid equipment and the comprehensive optimization index of the system consisting of load hydrogen deficiency rate and power abandonment rate as the objective function and the power regulation method for achieving maximum hydrogen production efficiency based on the characteristic curve of electrolyzer efficiency was proposed. The battery was selected to supplement the electrolyzer according to the fluctuation of the power of the scenery generation，and the elitist non-dominated sorting genetic algorithm（NSGA-Ⅱ）was written to solve the capacity configuration of each device in the system，and the multi-objective particle swarm optimization（MOPSO）was used to perform the maximum efficiency power regulation of the electrolyzer. In comparison to the scenery complementary hydrogen generation scheme，the capacity configuration model achieved a lower overall optimization index with a similar installation cost. After power regulation，the average electrolyzer input power fluctuation rate and electrolyzer efficiency decreased by 58.37% and 37.54%，respectively，which significantly improved the system stability and energy utilization.
