The active-frequency and reactive-voltage droop control method is one of the most widely used decentralized control methods in island-controlled microgrids. With the active-frequency droop control, it can be used to divide the exact active power between distributed energy sources, but the reactive-voltage droop, due to the high dependence on the line impedance and the load rate, often makes it worse to divide the reactive power between resources. Another challenge of the droop control is the frequency deviation and voltage mediated by load changes. In this paper, a new independent method for accurate account of reactive power between the distributed energy resources and the recovery of the micro-grid frequency has been provided. The proposed method improves the reliability and simplicity of the network. Simulation results show that the performance accuracy of the proposed method is especially about the correct splitting of reactive power and retrieval of the network frequency, as the difference in the reactive power of resources is reduced from approximately 1200 to 700 var and the network frequency is maintained on 314 radians per second.
Keywords: Frequency restoration, Reactive power sharing, Microgrid, Droop control, Decentralized control.
