Frequency control is significant to maintain the stability and reliability of islanded microgrids. Generation side controls, e.g., virtual synchronous generator control and droop control, have been widely adopted to stabilize the frequency of islanded microgrid. However, this is not ideal method due to the capacity limitation and power fluctuation of distributed generation(DG). Meanwhile, energy storage...
Droop control is an effective power sharing control scheme of distributed generation (DG) inverters in islanding AC microgrid, which can stabilize the grid as long as the distributed generation systems have sufficient residual power. On the contrary, many loads have equipped with power conversion circuits in front to improve the operational efficiency, e.g. air conditioners and LED lighting, which...
