Stabilising the Grid Voltage and Frequency in Isolated Power Systems Using a Flywheel Energy Storage System

摘要

This paper describes the control strategy and performance of aa grid connected flywheel energy storage system (FESS) installed to stabilise an isolated grid. The paper aims to demonstrate the concept of introducing aa flywheel and assisting its potential. The isolated power system studied includes diesel generators, hydro and wind turbines. The results from this study show that the stabilisation of an isolated power system is possible by the employment of aa flywheel energy storage system. The simulation an andd measured results showed clearly the affirmative influence of the energy storage on the transient system performance. The energy transfer from the flywheel into the grid increases the stability of the isolated power system. The simulation results were ve verified rified on aa real system.
