DVR COMBINATION WITH PHOTOVOLTAIC FOR IMPROVING THE OPERATION OF WIND FARM

Wind power is one of the most important kinds of renewable energies. Wind farm as a device which receives this energy needs some special conditions to work properly. The most common type of wind turbine is the variable-speed directly connected to the grid. Faults in the power system can originate the disconnection of wind farms. Dynamic voltage restorer (DVR) is a custom power device used for eliminating voltage sages and swells which is the result of the faults. This paper presents a simulation model of a 12-pulse DVR using photovoltaic (PV) as a mean of providing an alternative energy source for the DVR. Simulations were carried out using the Matlab Simulink. The simulation results proved the capability of PV-based DVR in eliminating voltage sag and swell distributed system. Improving the operation of wind farm as an energy generator and stabilizing its voltage is the main result of this work.
