Optimal Allocation Of Wind Energy System Capacity Based On Superconducting-battery-hydrogen Storage Hybrid

In the process of achieving the goal of "neutralization" in China,increasing the proportion of non-mineral resources is the most intuitive and efficient method.Therefore,there is an urgent need to explore a variety of stable clean and low-carbon energy in the new energy power system,so as to provide solid support and strong guarantee for the establishment of a safe and reliable operation system of the power system.In the context of the construction of new energy grid in China,hydrogen energy,as a main mode of electric energy conversion,is based on a variety of renewable energy hydrogen production technologies.The electricity-hydrogen utilization system can flexibly convert electricity-hydrogen energy into each other,and according to local actual conditions,form a multi-energy complementary system that meets the requirements of electricity-heating-cooling and other energy sources,which is an effective supplement to renewable energy power generation.This paper introduces the application of hybrid energy storage equipment,and analyzes the modeling of new energy wind power generation.At the same time,it analyzes the selected hydrogen energy storage,superconducting magnet energy storage,and battery,respectively introduces the energy storage principle.At the same time,it introduces the topology structure of the application of hybrid energy storage in the microgrid,and uses the semi-active topology structure for analysis,and introduces the control model and optimization strategy used in the capacity optimization configuration.And adopt improved particle swarm optimization(PSO)algorithmIn this paper,hydrogen storage,superconducting energy storage and storage battery are selected for different energy storage equipment,and the composite energy storage system is studied;The investment cost model of hybrid energy storage system is established,and the investment cost of different energy storage combinations is compared;At the same time,it studies the optimal allocation of system capacity;It further shows that the research has important reference value for the engineering application of hybrid energy storage system.
