Voltage control and reactive power management
shunt capacitors are used in power systems since the 1910s and are popular due to low cost and relative ease of deployment. The amount of reactive power supplied by a shunt capacitor is proportional to the square of the line voltage, so the capacitor contributes less under low-voltage conditions (frequently caused by the lack of reactive power).
