Optimal Configuration Method of Electric-Hydrogen Composite Energy Storage System

In order to solve the problem of optimal configuration of electro-hydrogen composite energy storage system, the whole life cycle cost calculation model of hydrogen energy storage and electrochemical energy storage was constructed, and a double-layer optimal configuration method of electro-hydrogen composite energy storage system was proposed. Considering the regulation and control requirements of the energy storage system to participate in the auxiliary services of the power grid, the charging and discharging power of electrochemical energy storage and hydrogen energy storage are calculated, and the optimal configuration scheme of the electric-hydrogen composite energy storage system is obtained based on the particle swarm algorithm. The example also shows that the income of the optimal configuration obtained under the control strategy in this paper is increased by 30.45% compared with that of the unconfigured energy storage.
