This paper presents a power system configuration and control schemes for a Multi-MW wind-solar hybrid system, which includes multiple wind turbines and solar panels to support a desalination plant. The wind and solar systems are sized such that the desalination plant obtains, as far as possible, its power from the renewable sources, to minimize the dependence on the utility grid. Each section of the wind turbine system includes a variable speed permanent magnet synchronous generator connected to the grid via a back-to-back voltage source converter. The rectifier operates the wind system at the maximum power point, and the inverter provides power to the desalination plant. The solar plant has multiple panels connected to the grid via a three phase converter, performing the dual functions of power transformation and maximum power point tracking. The modeling and validation of this system is performed with the PSCAD/EMTDC, a software typically employed for transient analysis.
