基于氢储能的直流微电网系统功率分配策略研究
Research on power distribution strategy of DC microgrid system based on hydrogen energy storage
摘要
Abstract
Based on a DC microgrid system coupled with photovoltaic power generation,lithium battery-supercapacitor hybrid energy storage,electrolysistank and hydrogen-burning micro gas turbine,a power allocation strategy that integrates the lithium battery state of charge(SOC)and hydrogen storage tank hydrogen state(LOH)is proposed.A PV-electrolysistank-micro gas turbine DC microgrid system model is constructed.The allocation logic of the power judgment module of the coordination control layer is designed,and three operation modes are given when the residual power exists in the DC network.The power allocation strategy is simulated and verified using MATLAB/Simulink software.The simulation results show that the power allocation strategy of DC microgrid system based on hydrogen energy storage can make the lithium battery charge state gradually converge to a reasonable storage interval and can improve the service life of lithium battery.关键词
