Abstract

The paper presents a cost-effective configuration for a Grid-Connected Wind-Photovoltaic Cogeneration system. In addition, topology provides an independent tracking of the maximum power point for both wind and solar to maximize renewable energy use. The solar is correlated with grid via Voltage Source Inverter (VSI), wind turbine based on a permanent magnet synchronous generator is correlated with the utility grid via Voltage Source Rectifier (VSR). The intermediate circuit capacitor was used for the direct connection of photovoltaic solar generator, DC/DC conversion is not required and therefore the hybrid system is simple and efficient. The detailed small-scale models for the system modules are developed to illustrate the overall stability. The impact of disturbances in the supply network on the performance of the system is examined. The simulation results under different operating conditions are presented to validate the stability of the proposed topology by using MATLAB/Simulink.
