Modeling and Control of Wind Power Conversion System With a Flywheel Energy Storage System

Abstract

In this paper, a control of a variable speed wind generator (VSWG) system based on a doubly fed induction machine connected to the network associated to a flywheel energy storage system (FESS) is considered. The maximum power point tracking (MPPT) method, the independent control power of generator, the grid connection, and the control of flywheel energy storage system are studied. The flywheel energy storage system consists of a power electronic converter supplying a squirrel-cage induction machine coupled to a flywheel. In order to validate the control method, the model of the system is simulated for different wind generator operating modes.
