For test cases A1 and A2, capacitors were treated as constant reactive power load. But if we treat the capacitor as constant impedance load, than the capacitor optimization problem will be more realistic.

For example, the configuration for a 5-stage capacitor bank with a 170 KVAR maximum reactive power rating could be 1:1:1:1:1, meaning 5*34 KVAR or 1:2:2:4:8 with 1 as 10 KVAR.

Capacitor banks provide reactive power compensation by introducing capacitive reactive power into the system, which is especially useful for counteracting the inductive reactive power typically drawn by motors and transformers. Capacitors store electrical energy in the electric field created between their plates when a voltage is applied.
