Induction machine‐based flywheel energy storage system modelingrnand control for frequency regulation after micro‐grid islanding

摘要

Imbalance between generation and consumption in each instant can result in frequencyrninstability. A storage device that responds quickly to changes and is capablernof energy injection or consumption in a microgrid (MG) can improve frequency stability.rnThe Flywheel Energy Storage System (FESS) has this characteristic. In thisrnpaper, a detailed model of the FESS is presented, and its control strategies for frequencyrnregulation are proposed and discussed. The field oriented control is usedrnfor machine‐side convertor control of FESS. Two MG islanding scenarios and thernperformance of the proposed control strategy are studied by MATLAB/Simulink.rnThe simulation results show good FESS performance with regard to frequencyrnchanges in the MG.
