Wind variation with respect to time
Hello , I have been doing dynamic simulations for the savnw case provided by PSSE using the GUI. I have introduced a Wind Turbine( WT4) at a bus and have attained the frequency response at that bus with a phenomena of sudden loss of generation at 10 seconds. I attained fairly descent plots of the frequency response and power of the wind. The Power (MW) graph shows steady state till 9 seconds and then drops at the 10th second where I created the event ( sudden loss of generation) and it stabilizes back after sometime. When I plot the wind velocity against time, I get a a flat line at 0, which shows that wind velocity isn't changing, which is not a practical scenario, as power generated from a wind turbine is never a constant value, it changes with the change in input which is the wind velocity ( as wind velocity varies with time). Hence I am trying to implement a scenario where my wind velocity changes with time and hence the wind turbines Pgen will also change with time as observed in a real situation. I have several questions to ask as I am unable to implement it :
- Do we need to use both Conec and/ or Conect subroutines to implement such kind of dynamic simulation in the time domain?
- I am unable to understand what Fortran code I'm supposed to write?
- Do I write it in the existing conec.flx file that is provided by PSSE?
- I am using GUI, how and where do I build these conec files?Is it in the command prompt that is present at the very bottom ( under the Output window) in the GUI or elsewhere?
I have read the POM and PAGV2, I understand a little bit, but I desperately need help from someone who can give me a brief explanation of the steps to be implemented to attain the time domain simulation where my wind velocity changes with respect t o time and is not a Constant.
Thank You very very much, I am eagerly waiting for your response.
