Improved droop control strategy for grid-connected inverters [PDF]
Sustainable Energy, Grids and Networks, 2015 An improved control strategy for grid-connected inverters within microgrids is presented in this paper. The strategy is based on the classical P-ω and Q-V droop method. The improvement in the proposed control strategy is twofold: Firstly, the transient response of the droop controller is improved by replacing the traditional method of measuring average
