Controlling power system parameters through reactive power (VAr) compensation | EEP
Shunt capacitor banks are mainly installed to provide capacitive reactive compensation / power factor correction. Because they are relatively inexpensive, the use of capacitor banks has increased. Shunt capacitor banks are composed of capacitor units mounted on the racks.
What is Reactive Power Compensation? – Capacitor Connect
The two terms look apparently synonymous, but power factor improvement implies that a lagging and low power factor has to be improved, which is done by adding leading reactive power. Reactive power compensation takes into account even the condition where receiving end voltage may be higher than sending end voltage.
