Capacitor switching on/off control for dynamic simulation

Anybody can help/direct with python coding to switch on the capacitor while a monitored bus voltage is lower than a threshold saying 0.95pu and switching off while voltage is higher than a limit saying 1.05pu? I need this auto control for dynamic simulation but I don't know how to setup the on/off function. Any help is appreciated.

This can be solved with dynamic model SWSHNT2.

Model the capacitor as a switched shunt in load flow with Vhi=1.05 and Vlo=0.96.
Use dynamic model SWSHNT2 with all CONs = 0 and ICON(M+1)=99. Any wanted intentional time delay for switching the capacaitor on or off may be given in PT1 and PT2.

The capacitor will now be automatically switched on when the bus voltage goes under 0.95 pu and switched off when the bus voltage goes above 1.05 pu.

Thanks Perolofl's quick help. Besides, this voltage trigger, is there a similar model for capacitor to switch on based on active power as the threshold instead of voltage Vhi/Vlo to meet power factor requirement also? My final goal is to get MW-triggered Cap control modeling in dynamic simulation
