The most useful method of capacitor placement in the power system is the analytical method. This uses the calculus for capacitor placements to calculate the minimum losses and cost savings. This method supposes that the feeder hasn‟t any sub branches. Its cross-section is the same in all parts and has been distributed equally in 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.
The notion of appropriate capacitor placement can only improve the system's performance. The combination of PLI and MLI was presented in this study as a novel approach for optimum capacitor placement. This has the potential to enhance the system's load capacity while simultaneously lowering power loss. The IEEE 15 bus system is used in the testing.
The objective of capacitor placement in the electric network is to minimize the losses and improve voltage profile. The load and capacitor model, objective function, constraints and power loss calculations are described in this section. The loads and capacitors are modeled as impedance. The impedance model of loads and capacitors are given by Eq.
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.
The ACO parameters are adjusted to find their optimal values. The ACO algorithm can be applied to find the optimal capacitor placement using the following steps: Insert the control variables that represent the capacitor locations randomly between 0 and 1 in the cases of fixed, switched and the combination of fixed and switched capacitors.
