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. |
