Abstract :

This paper proposes a new power–control strategy for grid–connected generation systems with versatile power transfer. Wind, Solar, Fuel cell and Battery systems are integrated in this work. An adaptive Maximum power point tracking system (MPPT) algorithm along with standard perturbs and observes method has been implemented. This system allows maximum utilization of freely available renewable energy sources like wind, fuel and photovoltaic energies. The objective of this work is to implement a novel five and seven level multi–string inverter topology for Distributed Energy resources (DER) based DC/AC conversion system. A high step–up converter is introduced as a front–end stage to improve the conversion efficiency of conventional boost converters and to stabilize the output DC voltage of various DERs. The proposed multilevel inverter requires only six active switches instead of eight as required in the conventional cascaded HBridge (CCHB) inverter. The DC output from non–conventional energy source is converted into AC power for synchronizing with the grid. This hyid system operates under normal and abnormal conditions with the support of the Battery Supply. The simulation results are presented to illustrate the operating principle, feasibility, and reliability of this proposed system.
