Due to rising public awareness of environmental protection, ever increasing energy demand and steady progress in power deregulation, alternative distributed generation (DG) systems have at-tracted increased interest. Wind and photovoltaic (PV) power generation are two of the most promis-ing renewable energy technologies. In this paper a detailed mathematical model and a control schemes for hybrid wind and PV based DG system with MPPT controllers for grid connected mode of opera-tion is developed. The wind power generation system uses wind turbine (WT), a permanent magnet synchronous generator (PMSG), a three-phase diode rectifier bridge, dc/dc boost converter with MPPT controller. The PV generation system uses PV array, a boost converter with maximum power point tracking controller. Both sources are connected to common dc bus with a dc link capacitor and supply power to load and utility grid through PWM voltage source inverter. The model developed for hybrid wind and PV system has been implemented in Matlab/Simulink environment. The performance of the developed model is studied for different nature of the individual DG source and load condi-tions. Simulation results show that the controllers can regulate the DC link voltage, active and reactive power produced by the hybrid DG system.
