The capacitor placement problem (CPP) has been widely studied throughout the years. However, traditional methodologies either do not consider non-linear loads in the formulations or are highly dependent on the spectrum of the harmonic currents. Therefore the traditional methodologies have become unsuitable for distribution system planning studies.
Recently, optimization of capacitor placement problem in distribution systems has attracted more attention because of increased electricity demand and voltage drop, which may lead to load-generation mismatch and uncontrolled islanding of radial and meshed grids [] [], Gaussian and Cauchy probability distribution functions based particle swarm optimization
Moreover, the optimal number of capacitor placement is the same with some other techniques, but the total power loss and the total kVAR injected by the proposed procedure are lower than those obtained using other techniques. Also, the overall power factor is improved after placement of fixed and switched capacitors.
Ceramic capacitors are the most popular type used for surface mount because of their small size, low cost, and high capacitance values. Electrolytic capacitors are larger and more expensive but can provide higher capacitance values. Tantalum capacitors are similar to electrolytic capacitors but are more reliable and have a longer lifespan.
