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 .
The detailed cost calculation method was chosen and complemented with a scale up using dimension analysis and analogy analysis, in order to be able to utilize this method since available data is either scarce or refers to laboratory scale. It was found that the researched cells are within the lower margin of costs reported in literature.
Etemadi and Fotuhi-Firuzabad used the particle swarm optimization (PSO) algorithm to find the optimal capacitor placement with separate objective functions: the first one was defined as the sum of reliability cost and investment cost, while the second was defined by adding the reliability cost, cost of losses, and investment cost.
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.
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.
