With the development of photovoltaic policy, a large number of PVs will be connected to rural networks, which cause the higher photovoltaic permeability in rural networks in the future. However, the PV of high-permeability will cause very serious reverse power flow in the rural networks, which will lead to the problems of overvoltage and the increasement of network loss, and which also seriously affect the safety of users. The relationship between the active power and reactive power of the inverter is analyzed. The quantization’s relationship between the voltage and the active power or the reactive power in the rural networks is analyzed according to the capacity characteristics of the inverter. In order to minimize the reduction of photovoltaic active power, an active and reactive power coupling control strategy is proposed. A multi-objective particle swarm optimization algorithm is adopted considering the characteristics of economy and the topology of rural networks. The results of simulation show that the proposed control strategy and the optimal control algorithm can not only guarantee the efficient usage of inverter’s active and reactive power, but also realize the optimization of network loss.
