Abstract: Abstract:Based on Matlab software platform, a photovoltaic cell model suitable to engineering calculation was established. The conductance increment method was used to realize the maximum power point tracking. The constant power control method (PQ) was used to control the inverter. Based on these, a complete operation and control model of the gridconnected photovoltaic power system was established. The simulation result shows that the model can reflect the operation characteristics of threephase gridconnected photovoltaic power system better and can track the dynamic output of the system, which is helpful to ensure the photovoltaic gridconnected power system to operate stably.
