液态金属电池储能系统在光氢耦合微电网中的优化配置
Optimal Configuration of Liquid Metal Battery Energy Storage System in Photovoltaic and Hydrogen Coupled Microgrid
摘要
Abstract
Liquid metal battery is a new type of battery.The integrated energy storage system composed of the liquid metal battery energy storage system(BESS)and the hydrogen energy storage system(HESS)can well meet the needs of the microgrid.Firstly,an economical scheduling scheme of the integrated energy storage system is designed,which enables two kinds of energy storage system to stabilize the fluctuation of on-grid photovoltaic power in coordination.Secondly,four indices, which are the cost of the BESS,the annual profit of the microgrid,the expected cycle life of the BESS,and the capacity deficiency days of the BESS,are calculated with the scheduling scheme.An integrated evaluation model for the BESS is established based on these four indices.Finally,a photovoltaic and hydrogen coupled microgrid is used as an example. Evaluation scores of different liquid metal battery capacities are calculated based on the above mentioned model and the optimal capacity of the BESS in this microgrid is obtained.关键词
