Research on High Proportion Renewable Energy of Hybrid Energy Storage Containing Hydrogen Storage

Abstract

Based on whether the hybrid energy storage system with hydrogen storage can well adapt to the problem of high permeability operation of renewable energy, this paper designs the hybrid energy storage configuration method with electric hydrogen coupling. Firstly, the structure of hybrid energy storage multi-energy complementary power generation system is established, followed by the objective function, which combines the cost, expected energy not supplied, and energy surplus rate of the energy storage system. Then, the particle swarm optimization algorithm is used to solve the optimization problem. Finally, by comparing with the traditional single battery energy storage system, it is concluded that the hybrid energy storage technology can well adapt to the operation of high permeability, not only can well reduce the rate of renewable energy abandonment, but also can effectively reduce the expected energy not supplied and cost.
