Frequency Support by Wind Farms in Islanded Power Systems with High Wind Power Penetration
Paper in proceedings, 2013

The purpose of this paper is to investigate the frequency support in low inertia systems that could be provided by a wind farm during load mismatch. Temporary instant inertia support and inertia emulation support are evaluated and compared. An improved control strategy is presented giving quick power delivery even during low wind speeds. The proposed model can support a loss of generation of 0.1 pu with a wind power penetration of 20 % without violating the 49 Hz limit. The paper presents this as a solution to allow wind turbines to act on frequency deviations in the fast manner before other production units has caught up and started to produce in accordance to the new power level required. The temporary frequency drop for a wind penetration of 50 % was improved from 47.33 Hz, for the uncontrolled case, to 49.10 Hz utilizing the suggested adaption of inertia support.
