Abstract

Abstract This paper examines the modeling and speed–based control of an IM–based flywheel energy storage system (FESS) for integration with a variable wind generation system (VSWG) feeding an online isolated load at the DC bus level. Two traditional control strategies are considered for the FESS, rotor flux oriented control (RFOC) and direct torque control (DTC). Instead of controlling the IM torque directly, the proposed schemes control the measured speed of the FESS–IM to follow a reference value estimated from the required power compensation. Matlab/Simulink simulations show that the tracking performance of the two controllers is comparable.
