This paper presents a new and efficient approach for capacitor placement in radial distribution systems that determine the optimal locations and size of capacitor with an objective of improving the voltage profile and reduction of power loss. The solution methodology has two parts: in part one the loss sensitivity factors are used to select the candidate locations for the capacitor placement an...

This paper presents an effective approach to simultaneous solution of capacitor setting and feeder reconfiguration for power-energy loss reduction and voltage profile enhancement in radial distribution systems. An optimization method using a Genetic Algorithm is proposed to determine the optimal selection size, location, type and number of fixed or switched capacitors as well as the open/closed...

This paper describes an advantageous method for using the capacitor banks in the distribution network, optimally. The aim is to determine the count, location and capacitor values in order to minimize the annual cost resulting from energy losses and capacitor bank’s installation cost. Besides, in the case of having nonlinear loads in the network, by installing capacitors in appropriate locations...

This paper has developed a novel multiobjective function for optimal sizing and sitting of Distributed Generation (DG) units and capacitor banks in simultaneous mode to improve reliability and reduce energy losses. The proposed function consists of four objectives: Cost of Energy Not Supplied (CENS), System Average Interruption Duration Index (SAIDI), costs of energy loss and investment. A nove...

In this paper, a new algorithm is implemented to solve optimal placement of capacitors in radial distribution systems in two ways that is, optimal placement of fixed or Discrete size of capacitor banks (Variable Locations Discrete sizing Capacitor banks-VLDC) and optimal sizing and placement of capacitors (Variable Locations Continues sizing of Capacitors-VLCC) for real power loss minimization ...

Point of common coupling (PCC) arrays are the most prominent and widely-used intermittent distributed generations (DGs). Due to right-of-way, environmental, economical other restrictions, connection these types DGs preferred point distribution network is very difficult or impossible in some cases. Therefore, because non-optimal locations, they may cause a voltage rise at PCC. In this paper, coo...

An interactive pareto optimal with advantage (IPOA) approach for bi-objective programming is proposed and applied on capacitor placement and sizing problem. Two main contradictory concerned which including cost and quality properties are considered as bi-objective programming formulation. The IPOA approach can provide a valuable trade-off pareto-optimal solution by following the intention of de...
