Synchronous Detection Method-Based Effective Power Transfer for Hybrid Wind-PV System

摘要

The present study is the energy conversion system to attain an effective power transfer using inexhaustible energy source such as wind and PV is allied as a hybrid system. The energy is supplied from source to load through a two voltage source converter (VSC) one at wind side and other at grid side. The control algorithm proposed for wind side converter are hysteresis current controller compares the actual and reference current of VSC to create gating pulses and fuzzy logic-based voltage controller. The hysteresis current controller is utilized in grid side to create gating pulse for grid side converter. The PV array coupled to the DC interface and one of the MPPT algorithms such as P&O calculation is utilized to track greatest power from PV under different weather condition. The synchronous detection method is used to compute reference current for hysteresis controller. To evaluate the performances of proposed scheme, Matlab/Simulink model is used. From the simulation results, it is confirm that effective power transfer is achieved with minimum number of converters.
