Capacitor Control

Wondering if a capacitor bank can be set to VAR control/voltage override in PSSE? I'm trying to get the cap bank to turn on/off based on the reactive power into the bus where the bank is connected and also force a voltage override when the voltage is soft. If this is doable, please let me know how it can be done. I' have access to PSSE 33 and 34 versions.

Thanks in advance for your help!

A capacitor bank can be in voltage control if you define it as a switched shunt.

What do you mean with "reactive power into the bus"? The total reactive power into a bus is (very close to) zero if the load flow is succesfully solved.

A switched shunt cannot control the reactive power flow on a branch.

Thank you for your response! I meant as an example, during a contingency configuration, a feeder may be taking more MW/MVAR load, in which situation, more MVAR would be drawn from this feeder, so I want the capacitor bank to go online and inject VARS into the system.
