Abstract: For the problems of coordinated power distribution, switching smoothness and voltage stability within the system during the operation of photovoltaic energy storage hydrogen energy micro-grid system, this paper proposes a power hierarchical coordinated operation strategy that considers the different demand commands of the system. A simulation model of the photovoltaic energy storage hydrogen energy micro-grid system was built with the aim of improving system stability, photovoltaic hydrogen system integration and smooth operation, On the one hand, the coordinated operation between the command layer and the controlled layer of the system is realized through hierarchical control, and the on-grid electricity price is used as a judgment indicator to guarantee the economic operation of the system; on the other hand, the system is categorized into eight operating conditions based on the system operating state, and the multi-power co-ordination control strategy enables the stable operation, smooth working condition switching and stable bus voltage of the optical storage and hydrogen micro-grid system. Finally, the correctness and effectiveness of the built model and control strategy are verified by simulation.
