Each type of microgrid's specific droop control objectives are explained, including power sharing, frequency and voltage regulation, and load balancing. The table also highlights the key variables, which are voltage, frequency, and power (both active and reactive).
In this work, a real time decentralized droop controller is implemented for an islanded DC microgrid to enhance the voltage regulation at the DC bus and current sharing efficacy between the sources subject to load transients. A novel control strategy is presented in which the conventional droop control is modified considering the load dynamics.
In order to improve power sharing performance, a big droop gain is often used, despite the fact that it often results in poor voltage regulation . By modeling the frequency droop control mechanism in AC microgrids, a virtual frequency droop control approach is provided to enhance the control performance of DC microgrids.
