| Abstract: | Based on the in-depth theoretical study and experimental analysis of the photovohaic power plant, the overall model of the MW PV power station is established and the dynamic output characteristics of the photovohaic power station and the equivalent impedance are analyzed. Furthermore, the effects on the local distribution system are studied through an example of a distribution network connected with a 1.6 MW PV power, with focus on power flow distribution, bus voltage, and short circuit current and relay protection and so on. |
