摘　　要：针对电力设备用电行为的不确定性,高峰时段集中大功率电力设备会导致虚拟电厂发生欠压问题,需要进一步研究虚拟电厂电压调峰控制策略。本文提出基于自适应方法的电压调峰控制,采用自适应虚拟阻抗法重建虚拟电厂的输出阻抗,进一步提高电压控制效率,并将虚拟电厂功率系数设置为相同。结果表明,当虚拟电厂功率发生波动时,采用自适应的电压调峰控制策略可以将虚拟电厂电压快速稳定在24V。随着电压峰值的增大,误差率也逐渐减小,且最大误差率从12.4%下降到1.2%,下降率为90.32%。当电压为300 V时,误差率从0%增加到1.2%,进一步表明基于自适应算法可以提高电压调峰控制效率,降低误差率。Due to the uncertainty of the power usage behavior of electric equipment,the concentration of high-power electric equipment during peak hours will lead to undervoltage problems in the virtual power plant,and it is necessary to further study the voltage peaking control strategy of the virtual power plant.In this paper,a voltage peak regulation control based on the adaptive method was proposed,and the adaptive virtual impedance method was used to reconstruct the output impedance of the virtual power plant,so as to further improve the voltage control efficiency,and the power coefficient of the virtual power plant was set to the same.The results showed that when the power of the virtual power plant fluctuated,the voltage of the virtual power plant could be quickly stabilized at 24 V by using the adaptive voltage peaking control strategy.With the increase of the peak voltage,the error rate decreased,and the maximum error rate decreased from 12.4%to 1.2%,with a decrease rate of 90.32%.When the voltage was 300 v,the error rate increased from 0%to 1.2%,which further shows that the adaptive algorithm based on the adaptive algorithm can improve the voltage peaking control efficiency and reduce the error rate.
