Small Wind Turbine Control with Frequency Support for Integration in Microgrids

Abstract

Enhancing the controllability of small wind turbines (WT) to support the frequency in microgrids (MG) requires different solutions than for high-power WT. This paper presents a sensorless control method for small fixed-pitch WT, which includes, besides the primary function of WT optimal control, a power curtailment technique that aims to improve MG stability during adverse operating conditions. Simulation results are presented to validate the proposed method.
