摘要

针对用户用电需求和可再生能源发电情况,提出一种由重力势能储能、蓄电池和超级电容组成的混合储能系统,建立其数学模型。针对其不同的特性,提出基于自适应变分模态分解的混合储能系统容量优化配置策略,对混合储能容量优化配置模型求解。以某风光互补电站典型日功率数据为例,对最佳储能系统的分解尺度K和高中、中低频分界点及其对应的储能配置进行优化分析,仿真结果验证所提方案的经济性和合理性。

Abstract

Based on power demand of users and renewable energy generation situation, in this paper, a hybrid energy storage system consisting of gravity energy storage, battery and supercapacitor is proposed, and the mathematical modelling of the hybrid energy storage system is established. According to different characteristics, a strategy of optimal capacity configuration of hybrid energy storage system based on adaptive variational mode decomposition is proposed and the optimal configuration model of hybrid energy storage capacity is sowed. The optimal energy storage system’s decomposition scale K, the frequency demarcation points and their corresponding energy storage configuration are verified on typical daily output data of a wind-solar generation station. It is indicated that the results reflect the economy and rationality of the proposed method.
