563 Abstract: The application of virtual synchronous generator (VSG) control in flywheel energy storage systems (FESS) is an effective solution for addressing the challenges related to reduced inertia and inadequate power supply in microgrids.
Therefore, the energy storage system (ESS) must be used to offer timely and stable frequency-regulation services for microgrids. In contrast to other ESSs, flywheel energy storage systems (FESS) provide distinct advantages in terms of high power density and efficiency, rapid responsiveness, and extended operational lifespan .
The prolonged operation of a flywheel energy- storage array (FESA) may result in an increasing speed differential among individual units. This phenomenon can cause certain units to exceed their state of charge (SOC) limits, thereby hindering their involvement in subsequent charging or discharging processes.
Consequently, interconnecting multiple modular flywheel energy storage units (FESUs) to form flywheel arrays is common practice . This configuration facilitates larger energy storage capacities, higher power outputs, and extended operational durations.
The virtual synchronous generator (VSG) technology imparts power to electronically interfaced equipment with inertia and damping features akin to synchronous generators (SGs), thereby offering an effective solution to the challenge of insufficient frequency support capacity resulting from the reduced share of SGs .
As evident, the control strategy proposed in this study enabled the flywheel to remain inactive within the frequency regulation dead zone. Simultaneously, the output power of the FESA adapted according to the SOC, thereby extending the discharge time while ensuring a frequency regulation effect.
