摘　　要：目前光伏AGC/AVC测试存在独立测试无法提供大容量环境,现场实际环境测试又会损失电站电量,造成一定经济损失的情况。对此,提出构建一种虚拟光伏逆变器,功能近似光伏逆变器,可实现天气变化动态调节有功、直控模式、无功电压变化等。通过虚拟光伏逆变器,不仅可搭建任意光伏容量电站,还能检测光伏AGC/AVC的调节控制性能。At present,the PV AGC/AVC test cannot provide a large-capacity environment by independent testing.The actual on-site environmental test of the photovoltaic AGC will also cause power loss of the power station and cause some economic loss.Therefore,this paper proposes to construct a virtual PV inverter with similar functions as the PV inverter,which can realize dynamic adjustment of active power,direct control mode and reactive power voltage variation in weather changes.With the virtual PV inverter,not only can any PV capacity power station be built,but also the PV AGC/AVC regulation and control performance can be detected.
