Abstract :
This paper presents a new topology of hybrid AC-DC standalone system based on solar photo-voltaic (PV) array and wind turbine (WT) feeding three-phase four-wire loads. The proposed hybrid system employs two back to back converters and dc-dc boost converter to achieve maximum power point tracking (MPPT). To balance the power at the PCC, the system is reinforced by BESS (Battery Energy Storage System) to keep constant frequency and voltage and to improve the power quality. The dump load is added to the system and is placed at the common dc bus to manage the extra power when the battery is fully charged. The capacitor bank is used to provide the reactive power to the doubly fed induction generator (DFIG). The proposed system is studied for various types of linear, nonlinear and dynamic loads and under varying climate conditions. The dynamic behavior of the proposed system is verified using MATLAB/Simulink.
