Under the background of the implementation of"dual carbon"policy,the importance of developing renewable energy such as offshore wind power has been increasing.However,the volatility of wind power brings about safety problems to the system operation.Therefore,this paper proposes an offshore wind power-multiple energy storage system that takes into account gas-solid two-phase hydrogen storage in combination with various energy storage technologies,and the requirements of safe operation of offshore wind power system are met through allocation of energy storage capacity.Firstly,the model of offshore wind powermultiple energy storage system is constructed,and the system structure and the energy flow are described.Secondly,the hydrogen storage system,which includes gas-solid two-phase hydrogen storage,is introduced,and the principle of solid-phase hydrogen storage is expounded.Then,an optimal allocation model of offshore wind power-multiple energy storage system is developed.Finally,a simulation is carried out with typical weekly operation data,and the results show that the proposed system can improve the safety and economy of the offshore wind power systems.
