Research on Control Strategy of Multi-Energy Complementary Microgrid for Wind-Solar Hydrogen Production

The multi-energy complementary microgrid system is an effective supplement to the areas not covered by the large power grid, and can effectively solve the problem of electricity consumption in remote areas. Based on the research of wind power, photovoltaic, energy storage, hydrogen production and fuel cell systems, this paper builds a wind-solar hydrogen storage multi-energy complementary micro-grid DC network system, and puts forward cooperative control strategies of the system under different working conditions, so as to achieve stable operation of the system and maximize energy utilization. Finally, PSCAD simulation software is used to establish a simulation model for each distributed unit to verify the stability and rationality of the control strategy. The simulation results show that the control strategy can achieve efficient, cooperative and stable operation between different energy sources on the premise of ensuring the power quality of the microgrid.
