摘要

为了提高全钒液流电池储能系统的效率

促进其高效利用

提出基于P-AWPSO （priority-adaptive weight particle swarm optimization）的功率分配策略。首先给出包含折损成本、损耗率及电池荷电状态（state of charge

SOC）一致性的多目标优化模型以及4个评价全钒液流电池储能系统功率分配的指标;然后采用P-AWPSO算法进行求解

该算法采用"先选择单元后功率分配"的思路

即先根据优先级选择参与本次功率分配的储能单元

然后在选定的储能单元内进行功率分配;最后将算法用于两个算例的仿真中

并与传统功率分配算法进行了对比。通过仿真表明

该策略能够实现全钒液流电池储能系统的功率分配

减少电池充放电次数

降低电池运行成本

提高工作效率。

Abstract

In order to improve the efficiency of vanadium flow battery energy storage system and promote its efficient utilization

a power distribution strategy based on priority-adaptive weight particle swarm optimization（P-AWPSO） algorithm is proposed. Firstly

a multi-objective optimization model including a compromise among the loss cost

loss rate and state of charge（SOC） is proposed

as well as four indexes to evaluate the power distribution of vanadium redox battery energy storage system. Then

a P-AWPSO algorithm is adopted to solve the problem. This algorithm uses the idea of ―selecting the unit first and then distributing the power‖

in other words

the energy storage unit which can participate in the power distribution is selected firstly according to the priority

and then the power distribution is carried out in the selected energy storage unit. Finally

the algorithm is used in the simulation of two examples and compared with the traditional power allocation algorithm. The simulation results show that the strategy can realize the power distribution of the vanadium redox battery energy storage system

reduce the charge and discharge times of the battery

reduce the running cost of the battery and improve the working efficiency.
