Abstract

This study presents the modelling and dynamic simulation of a high penetration wind diesel power system (WDPS) consisting of a diesel generator (DG) and a wind turbine generator (WTG). First the WDPS architecture and the models of the WDPS components are described. The WDPS is simulated in wind-only (WO) mode where the DG is not running and the WTG supply active power and in wind-diesel (WD) mode where both DG and WTG supply power. The simulation results are given showing graphs of the main electric variables in the WDPS (system frequency and voltage and active power in each component). Pitch angle controller is proposed which enables the wind turbine to regulate its active power in order to retain the frequency within prescribed limits. The pitch angle control enables the WT to smooth the load and wind power variations, so that the isolated system power quality is improved. The results shows that the WDPS incorporating pitch angle controller gives better results in terms of frequency regulation.
