为解决海岛、边防哨所等偏远地区电力供应困难的问题,计及体积功率密度约束,提出一种紧凑、可移动、含氢储能单元的预装式多元储能电站方案。针对预装式储能电站中氢储能、锂电池和超级电容器容量协调优化配置问题,分析微电网平衡功率频谱,基于不同类型储能单元响应特性,确定多元储能单元功率分配策略;通过储能系统成本结构分析,以年综合成本最小为目标,考虑集装箱功率密度、剩余电量、能量溢出率与负荷缺电率等约束,采用遗传算法求解模型,得到多元储能单元容量优化配置方案。最后,实例验证了所提方法的适用性与经济可行性。

In order to solve the problem of power supply difficulties in remote areas such as islands and border posts,and taking into account the constraints of volume power density,a compact,movable,hydrogen-containing energy storage unit pre-installed multi-energy storage power station solution was proposed.Aiming at the problem of coordinated and optimized allocation of hydrogen energy storage,lithium battery and supercapacitor capacity in pre-installed energy storage power stations,by means of analyzing balanced power spectrum of micro grid,the power distribution strategy of multiple energy storage units was determined based on the response characteristics of different types of energy storage units.By analyzing the cost structure of the energy storage system,aiming at the minimum annual comprehensive cost and considering the constraints such as the container power density,remaining electric quantity,energy overflow rate and load power shortage rate,this article uses the genetic algorithm solves the model to obtain the optimal allocation scheme of the capacity of multiple energy storage units.
