Study and Analysis of Wind-Diesel hybrid system by Simulink
Wind Diesel Hybrid Systems (WDHS) are isolated power systems which combination of Diesel Generators (DG) with Wind Turbine Generators (WTG). Depending on the generators which are supplying high penetration (HP) WDHS have three operation modes 1) Diesel only DO 2) Wind Diesel WD & 3) Wind only WO.The DE can be engaged (DO & WD modes)or disengaged (WO mode) From the SM by means of a clutch. The WDHS presented in this paper consists of a Diesel Engine DE, Synchronous Machine (SM) a Wind Turbine Generator the consumer load , a Ni-Cd Battery based energy Storage System(BESS) and a Dump Load. Simulation results with graphs for the frequency and voltage of the isolated power system, active powers generated by the different elements and the battery voltage , current , state of charge are presented for a load charge in WO mode and for the transition from WO to WD mode in order to substitute a supplying BESS for the DE as the active power source.
