OPTIMIZED GRID INTEGRATION OF WIND-PV HYBRID SYSTEMS USING BACK-TO-BACK VOLTAGE SOURCE CONVERTERS

The novel configuration for a grid-connected wind-solar cogeneration system is described in this study. The defining characteristics of the proposed topology are its simplicity and exceptional efficiency. The utility grid is connected to a wind turbine that is outfitted with permanent magnet synchronous generators and back-to-back voltage-source converters (VSCs). Using the dc-link capacitor, a photovoltaic solar generator was directly connected to the system. The simplification and effectiveness of the hybrid system are enhanced by the elimination of dc/dc conversion phases. The suggested configuration integrates a technological system that monitors the optimum power points of wind and solar generators in order to optimize the harvesting of sustainable energy. In the rotating reference frame, the VSCs are governed by vector control. Component-level small-signal model construction determines the system's overall stability. Additionally, the operational effects of utility grid disruptions on the proposed system are investigated in depth. Effectiveness of the proposed topology is demonstrated through the presentation of simulation outcomes in the nonlinear time domain for various operational scenarios.
