摘要:

针对孤岛运行模块化多电平变流器-半桥串联结构微电网(MMC-MG),结合其结构特点提出了一种基于改进特征模态分解(FMD)算法的混合储能系统(HESS)容量优化配置方法。首先根据HESS的参考功率,利用秃鹰搜索(BES)算法对FMD进行参数寻优,将需要平抑的功率分解为高频和低频分量;再分别由超级电容和锂电池进行平抑;最后根据电池充放电约束,以全生命周期成本最小为目标,对容量进行优化配置,实现成本最小化。仿真结果证明,所提方案有效减少了容量配置的成本,同时实现了混合储能的功率协调。

Abstract:

For the modular multilevel converter half-bridge series microgrid (MMC-MG) operating in island mode,a capacity optimization configuration method for hybrid energy storage systems (HESS) is proposed,leveraging its structural characteristics based on an improved feature mode decomposition (FMD) algorithm.Initially,the reference power of the hybrid energy storage system is used to optimize FMD parameters via the bald eagle search (BES) algorithm,decomposing the power to be smoothed into high-frequency and low-frequency components.These components are then mitigated by supercapacitors and lithium batteries,respectively.Finally,considering battery charge-discharge constraints and minimizing the total lifecycle cost as the objective,the capacity is optimized to achieve cost minimization.Simulation results demonstrate that the proposed scheme effectively reduces the cost of capacity configuration while achieving coordinated power management in hybrid energy storage systems.
