Reactive power control for a small wind farm connected to infinite grid

Credits to selman sekai. This file is modified from submission file id# 44746. A test system consists of 20 MVA type III variable speed wind turbines, 10 MVA type I fixed speed wind turbine generators and ±3 MVAr STATCOM connected to 25 kV medium voltage collection bus. This test system is investigated for reactive power management with the 230 kV power grid. An algorithm is written in the master controller titled"reactive management". In this algorithm, the reactive power references are computed using the voltage and net reactive power at the point of interconnection and their values are proportional to each of the individual quadrature axis current components. The voltage dips are programmed by creating a voltage event at t=5 sec and by changing the wind speed of fixed speed wind turbine from 8 m/sec to 10 m/sec at t=11 sec. Figures and matlab code for plotting the figure are included with the submission
