As more and more unconventional energy sources are being applied in the field of power generation, the frequency fluctuation of power system becomes more and more serious. The frequency modulation of thermal power unit has disadvantages such as long response time and slow climbing speed. Battery energy storage has gradually …
Traditional auxiliary control methods often adopt a centralized design consisting of drooping control, unit processing, and central control. While these criteria reduce MGs'' reliability and adaptability and increase their vulnerability to perturbations, the failure of a single unit can lead to significant problems for the entire MG [ 76, 82, 83 ].
