基于SOC实时反馈的HESS平抑光伏功率波动策略
Photovoltaic Power Fluctuation Smoothing Strategy Based on SOC Real Time Feedback Hybrid Energy Storage System
摘要
Abstract
A hybrid energy storage system consisting of lead-acid batteries and supercapacitors was adopted to stabilize PV power fluctuations. According to the different characteristics of lead-acid battery and supercapacitor,a control strategy of hybrid energy storage system based on wavelet packet decomposition was proposed to realize the primary allocation of the original power. In order to solve the problem of large fluctuation and positive and negative variation of the above components,the fuzzy control was used to correct the power reference instructions of the energy storage device. Based on the Kalman filter,the charging state of the energy storage device was monitored in real time, the charge and discharge of the energy storage device were controlled reasonably,and the service life of the energy storage device was prolonged. The simulation model of photovoltaic hybrid energy storage system was built in Matlab/Simulink,and the coordinated control strategy was simulated and verified. The simulation results show that the proposed coordinated control strategy is feasible.关键词
