Insufficient frequency stability has multifaceted impacts on microgrids, affecting the normal operation of equipment and power quality, increasing economic costs and safety risks, and reducing the overall performance and reliability of the system. . Motors and Generators: Frequency fluctuations can cause instability in the speed of motors and generators. Electronic Devices: Many electronic devices are highly sensitive to. . Islanded microgrids commonly use droop control methods for autonomous power distribution; however, this approach causes system frequency deviation when common loads change. In such cases, the distributed generators (DGs) must be controlled in a decentralized fashion, based on the locally available measurements.
