|
摘要
为提高系统响应速度,缩短耗时,延长蓄电池的使用寿命,针对传统PI控制的不足,选取模糊控制优化蓄电池充放电控制,采用电压源型变换器平抑输出功率波动,设计了一种风光互补蓄电池能量管理系统。在MATLAB/Simulink平台搭建系统仿真模型,仿真结果显示,模糊控制响应速度快,控制效果好;并网电流与网侧电压保持同相位,跟踪性能好;设计的风光互补蓄电池能量管理系统具有良好的能量控制管理效果。
In order to speed up the system response, shorten the time consumption and extend the lifespan of batteries, a Wind-PV batteryhybrid power systemwas designed using the fuzzy control strategy to optimize the battery charge and discharge control and the voltage source converter to suppress the output power fluctuation.Results of the overall system simulation model on the Matlab/Simulink platform show that the system has fast response and good control effect,the grid-connected current and the grid-side voltage stay in same phase to have good tracking performance, and the designed energy management system of Wind-PV hybrid power system based on battery has good effect for energy control management.
