A dSPACE-based control of a hybrid renewable energy system with wind and photovoltaic power

In recent years, non-conventional sources of energy such as wind and solar have gained increased attention as viable means of power generation. This paper discusses a hybrid scheme consisting of a permanent magnet synchronous generator (PMSG)-based wind energy system and photovoltaic panels which are integrated with a battery to store extra energy when available and to meet additional power requirement during shortage. The PV panel supplies the battery through a SEPIC converter for maximum power point tracking (MPPT). The PMSG supplies the battery through a boost converter which regulates the output. The outputs of the wind and photovoltaic systems share a common DC link through which the total power from the hybrid system is fed to a three-phase load using an inverter implementing space-vector pulse-width modulation (SV-PWM). The controller modeled in MATLAB/Simulink software is simple and is implemented through real-time simulation using dSPACE board.
