Modelling of a hybrid renewable energy conversion system
A hybrid renewable energy conversion system based on solar panels and wind turbine is designed and analysed in this paper. Each separate energy conversion system is controlled either using pure PI controller or extended PI controller that has auxiliary controllers such as Perturb and Observe algorithm. The solar farm model is constituted by connecting 170W photovoltaic (PV) panels serially and energy conversion is performed with maximum power point tracking (MPPT) algorithms in buck converter. The MPPT algorithm utilized in the control step of converter is developed using Perturb and Observe (P&O) that is extended with PI controller. The wind energy conversion system (WECS) is designed with a permanent magnet synchronous generator (PMSG), and the AC-DC conversion stage is constituted with an uncontrolled full-bridge rectifier. All the converter outputs are connected to busbar over interphase transformers (IPT). The DC bus-bar voltage is supplied to a full bridge inverter to generate three-phase AC voltages at the output of inverter. The three-phase inverter is controlled with sinusoidal pulse width modulation (SPWM) scheme which is developed with phase shifted carrier signals. Measurement results and obtained three phase voltage are analysed in detail.
