Review on Wind Diesel Systems Dynamic Simulation

Abstract

Wind diesel power systems (WDPS) are isolated microgrids which combine diesel generators (DGs) with wind turbine generators (WTGs) to supply a community of consumers. A WDPS can work in three mode of operation: Diesel Only (DO) where only the DGs supply power, Wind Only (WO), where only the WTGs supply power and Wind Diesel (WD), where both type of generators supply power. WDPS dynamic modeling allows short-term simulations in order to test the WDPS stability and power quality. This paper does a review of recent papers on the subject of WDPS dynamic simulation taking into account factors as the WDPS operation mode simulated, the WTG type used in the WDPS or the use of Energy Storage Systems to increase system power quality and stability. Finally using the modeling capabilities of Matlab-Simulink a WDPS consisting of one DG, one WTG, load and a dump load (DL) is modeled. The WDPS is simulated against load and WTG power variations and simulation results show the use of the DL to increase the WDPS stability.
