Sumario:Power-sharing in a microgrid community (MGC) requires mandatory strategies in order to stabilize the system by maintaining the rated frequency and voltage. The hierarchical control strategy is the most adopted control structure due to providing seamless operation in transient between islanded and grid-connected modes. Droop control strategy is discussed in this paper to control the voltage source inverter (VSI) in power exchange mode with other microgrids (MGs) or main utility grid. After analysing the average model of three-phase VSI, the voltage and current transfer functions are obtained according to the considered droop controller. The stability and seamless operation of the system are analysed, and the simulation results verify the control loops of the VSI can handle the power variation of the MG effectively.
