Modeling and Simulation of Solar PV and DFIG Based Wind Hybrid System ¬リニ

The increasing energy demand and depletion of fossil fuels has risen in awareness of searching for alternative energy source thus the inexhaustible solar and wind energy is becoming an interesting topic which has grabbed the attention of researchers to make it sustainable power. The objective of this paper is to provide sustainable power for rural areas and remote places.This paper gives the architecture of hybrid system. The proposed system consists of solar PV and Doubly Fed Induction Generator (DFIG) based wind turbine. In Solar PV MPPT technique is used to maximize the power and boost converter is used to rise the DC voltage of solar PV and fed to the three phase PWM inverter. The DFIG has two controllers Rotor side control and Grid side control. Rotor side converter and Grid side Converter have the capability of generating or observing reactive power and to maintain constant rotor speed, and controls the DC-link voltage, controller for boost converter, inverter AC-DC-AC is implemented using vector control method. Simulation study of the proposed system is carried out with MATLAB Simulink and simulation results are provided. © 2015 The Authors.Published by Elsevier Ltd.
