Custom power systems and software platforms for wind farms under voltage dips situations

Wind generation is one of the most important renewable energy technologies. The most common type of wind turbine is the fixed-speed directly connected to the grid. Faults in the power system can originate the disconnection of wind farms. Grid codes appear. Custom power systems, such as D-STATCOM and DVR, are needed for helping old wind farms to withstand the sag. DFIG with the appropriate converter control can comply with grid codes. For simulating and testing the behavior of DFIG, an adequately software platform is needed. Here, the comparison between Matlab SimPowerSystems Vs Matlab-PSIM co-simulation for solving the problem is studied. The PSIM-MATLAB co-simulation is found to be advantageous for analyzing, e.g., DFIG converters in dynamic simulations.
