Throughout the process of reviewing the existing FESS applications and integration in the power system, the current research status shows that flywheel energy storage systems have the potential to provide fast and reliable frequency regulation services, which are crucial for maintaining grid stability and ensuring power quality.
Frequency fluctuations are brought on by power imbalances between sources and loads in microgrid systems. The flywheel energy storage system (FESS) can mitigate the power imbalance and suppress frequency fluctuations.
Moreover, flywheel energy storage system array (FESA) is a potential and promising alternative to other forms of ESS in power system applications for improving power system efficiency, stability and security . However, control systems of PV-FESS, WT-FESS and FESA are crucial to guarantee the FESS performance.
The flywheel energy storage system (FESS) can mitigate the power imbalance and suppress frequency fluctuations. In this paper, an adaptive frequency control scheme for FESS based on model predictive control (MPC) is proposed to suppress the frequency fluctuation in microgrids.
Compared to battery energy storage system, flywheel excels in providing rapid response times, making them highly effective in managing sudden frequency fluctuations, while battery energy storage system, with its ability to store large amounts of energy, offers sustained response, maintaining stability .
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
