Abstract :
Within Wind-PV-Diesel Hybrid System various power sources are connected to common DC bus through DC/DC converters, controlled with MPPT algorithms. In this case DC bus voltage is maintained on a constant level, decreasing a power efficiency of the whole system. In this paper the possibility of DC bus voltage regulation in relation to on service variation of generators installed power in order maximize power efficiency of the system and to minimize the fuel consumption of diesel generator. The possibility of stabilization of output AC voltage of autonomous inverters in cases of DC-bus voltage drop by means of autonomous inverter switches control.
