Abstract

Due to the effect of tower shadow and wind shear, a wind farm may inject periodic fluctuation power to the grid. In this paper, the origin of forced low frequency oscillation introduced in power systems by a wind farm is investigated. A control strategy of flywheel energy storage system is proposed with the aim to eliminate forced oscillation power by designing a reference power calculation model. The simulations validate the effectiveness of this control strategy. This work provides a new solution to suppress the forced oscillation source, especially for a wind farm combined with an energy storage system.
