Abstract

The contribution of a renewable power source to the total power generation becomes more and more important. Wind and photovoltaic (PV) power generation are two of the most promising renewable energy technologies. This paper presents modeling, simulation and performance analysis of wind energy and PV based DG systems for grid connected mode with MPPT algorithm. Each energy system is connected in parallel to a common dc bus line through non-isolated dc–dc boost converter. These two dc–dc boost converters are employed for MPPT of wind energy and PV systems. Perturb and Observe (P&O) technique is used for wind energy system. For PV system MPPT algorithm based on incremental conductance is used to get maximum power output. The performance of the developed model is studied for different nature of the individual DG sources and load conditions. Simulation results show that the controllers can regulate the DC link voltage, injected powers and also the dc–dc converters are very effective in tracking the maximum power of the wind and photovoltaic sources
