Frequency Regulation of PMSG Based Wind Turbine Considering Location Identification Technique in High Penetration of Renewable Generation System

Abstract

Frequency regulation participation of the permanent magnet synchronous generator (PMSG) wind turbine (WT) is rigorously practiced nowadays with the increasing penetration of renewable generation in the generation mix. In line with the objective, a novel location identified frequency control (LIFC) is proposed by the authors, that select locationally targeted remedial frequency control measures in a decentralized manner and does not depend on system-wise observability. The first component of the LIFC is an attuned power balance factor (APBF) which takes the tie line power into consideration for quick response by the PMSG for enhanced load frequency control (En-LFC). The second term of LIFC is the inertial and primary frequency control loop, and act on the frequency variation over time in the dynamically changing power system. The real-time simulation result shows that the performance of LIFC is fast in action and provides overall frequency support to the grid at the time of frequency events.
