Abstract:
A Wind Diesel Hybrid System (WDHS) is any autonomous electricity generating system using Wind Turbine Generators(s) (WTG) with Diesel Generator(s) (DG). High wind penetration Wind Diesel Hybrid Systems (WDHS) have three modes of operation: Diesel Only (DO), Wind Diesel (WD) and Wind Only (WO). In this article a no-storage WDHS with a DG with a clutch to engage/disengaged the diesel engine (DE) from the synchronous machine is simulated. The simulation includes the WO mode and the necessary transition from WO mode to WD mode when the active power produced is less than consumed. It is shown in the graphs that once the lack of active power in WO mode happens, the DE corrects the system frequency after the clutch locks with a maximum overshoot of +1,1 %, a settling time of 6,668 s and with a maximum/minimum voltage variation of -2,9/+3,25%, which are very reasonable values taking into account the strong system disturbance.
