As the core component of microgrid

the capacity configuration of energy storage system directly affects the economy of system operation. In this paper

a hydrogen-electric hybrid energy storage scheme is proposed to optimize the configuration of the wind-PV-hydrogen microgrid system. Based on HOMER Pro simulation software

an optimization model is constructed to minimize the total net present value (NPC) of the system as the objective function

taking into account the load loss rate. The simulation results show that

compared with the traditional energy storage method

the proposed hybrid energy storage scheme has dual advantages in economy and security under the premise of ensuring the reliability of power supply.
