Contribution of small‐scale wind generation to primary frequency control

Abstract

SUMMARY The connection of small‐scale embedded generation to the grid may influence the frequency and voltage stability of the power system. A load‐frequency control technique for systems with high penetration of small‐scale wind generation is proposed. The proposed controller has been successfully implemented and tested using PSCAD/EMTDC (PSCAD Power System Simulation, HVDC Research Centre, Manitoba, Canada). In this study, the impact of small‐scale wind turbines on frequency stability of the system is studied in detail. This study shows that large penetration of small‐scale wind turbines with load and frequency has a significant impact on the stability and security level of electrical network.
