Grid-connected control of PV-Wind hybrid energy system

ABSTRACT Article history: Received Oct 14, 2020 Revised Mar 22, 2021 Accepted Apr 23, This paper presented a strategy for modeling, simulation and control of hybrid grid connected power system which is in fact rather complex system. In this work, we study how to use two renewable energies an efficient manner without any disturbing the main network. Our energy (HES) composed by sources, photovoltaic source wind source. It better these systems work at their maximum order return investment cost The proposed solution connect those generators electrical via AC bus with trackers. Where generator (PVG) followed DC/DC boost converter, controlled perturb observe (P&O) tracker, then three-phase voltage inverter (3-ph-VSI) watt-var decoupled method. based on permanent magnet synchronous machine (PMSM) used as variable speed directly turbine (without gearbox) back-to-back converters. side converter (GSC) allows us DC unity factor, while (MSC) ensures PMSM speed. Knowing that pitch angle not considered our study. MPPT strategy, optimum peak ratio (OTSR), ensure most efficiency despite variations coupling done Point Common Collecting (PCC). Finally, results show feasibility good performances applied mediumsized HES generation. They also demonstrate such topology very advantageous.
