Yes, it is possible, using python, outside the QV module in PSSe. I copied the code posted at "https://psspy.org/psse-help-forum/question/341/will-this-generate-a-qv-curve/" and re-arranged it for this task. The zip file contains the code and a savnw case (good for v.32 and 33) with in-serviced switched shunts at bus 153. Adjust the parameters of the code to fit your scenario.

Inside the QV module in PSSe, set to 1 the item 3 in the LFoption list to allow shunt switching!!

Thank you so much for your help. It works as I wish. However, QV characteristics of buses having switched shunts were plotted in base case MODE as I understand. Is it possible to plot the QV curves in this case with contingency MODE?

The plotting works for both modes. To get the QV response under contingency, load the case, apply the contingency, solve and save. Use this 'new' case as input to the QV_calc script.
