摘　　要：针对传统控制的电压、频率存在的有差调节问题,提出了交直流混合微电网互联逆变器改进控制策略。该控制策略是将电压补偿值与频率补偿值输送到PI控制器,得到的补偿电流再与参考电流进行叠加,最终使交流频率和直流电压进一步接近额定值。通过对比仿真实验的结果,验证了该文所提出的方法的有效性和优越性。An improved control strategy of AC-DC hybrid microgrid interlinking converter is proposed to solve the problem of differential regulation of voltage and frequency in traditional control.The control strategy is to transfer voltage compensation value and frequency compensation value to PI controller,and the compensating current is superimposed with reference current,finally,the AC frequency and DC voltage are closer to the rated value.The effectiveness and superiority of the proposed method are verified by comparing the simulation results.
