摘　　要：将有源功率因数校正技术(Active Power Factor Correction,APFC)引入直流储能单元的电容电压控制,是一种用以治理微电网电能质量问题的新型管理方法。该方法基于组合控制器的拓扑结构,采取储能单元和有源电力滤波器补偿电容并联的形式,实现多重电能质量调节功能,稳定了电容电压,提高了电容器的安全性能;此外,该方法对系统进行无功补偿,提高了储能单元的使用效率,使风光储能一体化系统的电能质量得到有效改善。算例结果表明,在有功功率不足的情况下,该系统能够在0.077 s内快速响应。The introduction of Active Power Factor Correction(APFC)into capacitor voltage control of DC energy storage unit is a new and innovative management method to deal with power quality problems in microgrid.The topology structure of the combined controller is given,and the multiple power quality regulation function is realized by taking the form of energy storage unit and active power filter compensation capacitor in parallel,and the capacitor voltage is stabilized to improve the safety performance of the capacitor.In addition,the scheme compensates the reactive power of the system,thus improving the efficiency of the energy storage unit.The problem of power quality in wind-wind energy storage integrated system has been effectively improved.The results show that the system can respond quickly in 0.077 seconds under the condition of insufficient active power.
