Abstract. Power fluctuations of wind generators may affect power quality especially in weak or isolated grids. This paper proposes an energy management strategy for a flywheel-based energy storage device. The aim of the flywheel is to smooth the net power flow injected to the grid by a variable speed wind turbine.
This high-speed FESS stores 2.8 kWh energy, and can keep a 100-W light on for 24 hours. Some FESS design considerations such as cooling system, vacuum pump, and housing will be simplified since the ISS is situated in a vacuum space. In addition to storing energy, the flywheel in the ISS can be used in navigation.
This research topic focuses on all aspects of advanced component energy storage devices and their integration for HESSs. System modeling and state estimation Accurate modeling such as equivalent circuit ( Tang et al., 2021 ) or electrochemical models ( Liu et al., 2022b ) and state estimation are the basis of energy storage system management.
