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 …
The limitation factor for allocating capacitor banks in distribution systems is their investment cost . For capacitor allocation, their lifecycle costs, including installation, O&M, and size (namely kVar) costs, must be considered for allocating capacitors in distribution systems, like other installation problems [4, 5]. Capacitor banks should ...
