There was a notable reduction in active power losses (I2R losses) throughout the distribution lines. The optimized capacitor placement minimized the current flow, thereby reducing resistive losses. Capacitors provided local reactive power support, reducing the amount of reactive power that needed to be transmitted over long distances.
Use the average reactive loading profile to optimally size and place capacitors for energy losses. If we use the peak-load case, the 1/2-kvar method optimizes losses during the peak load. If we have a load-flow case with the average reactive load, the 1/2-kvar method or the 2/3 rule optimizes energy losses.
The most popular result of analytical methods is the (2/3) rule. According to this rule, in order to come up with the maximum reduction, a capacitor with (2/3) drag reactive power from the beginning of the feeder must be installed in a place where its distance is (2/3) feeder length in comparison to the beginning of the feeder.
In [111, 112], a two-stage method was used to solve the optimal capacitor placement problem. First, the power loss index (PLI) in and the LSFs in were utilized to determine the high potential buses for capacitor placement.

Reducing the switching frequency at light loads reduces both switching losses and gate-driving losses and thus improves efficiency.
