摘要
本文以并网型风光氢储微电网为研究对象,在满足年制氢量任务的前提下建立了以系统年收益最大为目标的经济优化模型,对不同储能容量方案采用含罚函数的粒子群算法进行优化调度求解.最后对液态金属电池、液态金属电池-铅酸电池、锂电池、锂电池-铅酸电池四种储能配置方案进行对比研究,发现液态金属电池现阶段因价格高单独使用时优势不明显,而在混合储能系统中可以与铅酸电池优势互补.
Abstract
In this paper,the grid-connected wind/PV/hydrogen/storage micro grid is taken as the research object,on the premise of meeting the annual hydrogen production task,an economic optimization model aiming at the maximum annual income of the micro grid is set up,and the particle swarm algorithm with penalty function is used to solve the optimal scheduling problem of different energy storage capacity schemes. Finally,such four energy storage configuration schemes as liquid metal battery(LMB),liquid metal battery-lead-acid battery(LMB-LCB),lithium battery(LIB)and lithium battery-lead-acid battery(LIB-LCB)are compared,finding that liquid metal battery has no obvious advantages in the independent use at present stage due to high price,but can complement the advantages of lead-acid battery in hybrid energy storage system.
