摘　　要：针对传统采用分布式电源(DG)不能完全补偿由不平衡及非线性负载引起的微电网供电电压质量下降的缺点,此处提出一种基于DG和有源电力滤波器(APF)协同的微电网电压及谐波补偿控制策略。构建了包含分布式2次控制器、DG本地控制器在内的微电网控制体系,分别通过DG与APF实现对微电网不平衡/谐波电压及负载谐波电流的补偿与抑制。最后,通过所构建的包含两台DG和一台APF的微电网动模实验平台,验证了所提控制体系及策略的有效性和可行性。Aiming at the disadvantage that the traditional distributed generation(DG)can not fully compensate the micro-grid voltage quality decline caused by unbalanced and nonlinear loads,a voltage and harmonic compensation control strategy of micro-grid based on DG and active power filter(APF)cooperation is proposed.The micro-grid con-trol system including distributed secondary controller and DG local controller is constructed.The unbalanced/harmonic voltage and load harmonic current of the micro-grid are compensated and suppressed by DG and APF respectively.Fi-nally,the validity and feasibility of the proposed control system and strategy are verified through the micro-grid dy-namic mode experimental platform which contains two DGs and one APF.
