Consider the example in the Simulink documentation Wind Farm (IG) that is originally designed to input 9 MW into a network (type power_wind_ig in the command window and it will take you to the file). Modify this design to accomplish the following requirements: Increase the power capacity to 12 MW. Deactivate the 3-phase short circuit. Variable wind speed input generated by a Raleigh distribution with scale parameter 8 and shape parameter 2, range 6 to 18 m/s. The speed must change every 4 seconds for a 30 second simulation. a. Show the outputs for a 30 second simulation. Find a way to display the torque of the turbines for this simulation. b. What is the purpose of the capacitors at the output of the generators? What happens if the capacity of these capacitors is cut in half? Explain with results. c. What is the purpose of the STATCOM? What happens if you replace it with a fixed capacitor? Explain with results. d. Change the pitch control gain of the turbines to Kp=10 and then to Kp=100. Wh
