Design and simulation of island integrated energy system based on diversified power generation and efficient energy storage

The island is rich in renewable energy, in order to respond to the energy development strategy with Chinese characteristics, and to help build a clean, low-carbon, safe and efficient energy system, this paper designs an integrated island integrated intelligent energy system with cooling, heating, electricity, hydrogen and water co-generation. The project adopts a multi-energy complementary renewable energy co-generation system to establish a diversified supply system, and also designs a compressed air energy storage system coupled with a refrigeration unit, an integrated hydrogen energy system integrating electrolysis hydrogen production - gas-solid two-phase hydrogen storage - hydrogen fuel cell, which innovatively combines the utilization of waste heat and seawater desalination, and a lithium-ion battery storage system, to make full use of the adjustable resources and significantly improve the efficiency of the island's energy system. The system makes full use of adjustable resources and significantly improves the adjustment and response capability of the energy system.
