title: How to access PSSE working case variables by Python a code
body: <p>I am a transmission planning engineer and trying to automate the execution of PSSE 100 times or more at one go through a Python code. I already runs, change loads, reruns psse and write bus based summary report to *.csv file. What I really want to do is select the first active power load variable of a PSSE case and increase it by 1 MW. Then run psse, write results to a csv file. Change the selected load back to its original value and move on to the next active load to do the same again and again until I have done same for all load busses.</p>
  
  <p>This will help me to calculate transmission loss factors for entire network with one go.</p>
  
  <p>Thanks</p>
