Individually Network reconfiguration or Capacitor control perform well in minimizing power loss and improving voltage profile of the distribution system. But for heavy reactive power loads network reconfiguration and for heavy active power loads capacitor placement can not effectively reduce power loss and enhance voltage profiles in the system. In this paper, an hybrid approach that combine ne...

This paper presents an ant colony approach optimization to shunt capacitor placement on distribution systems under capacitor switching constraints. The optimum capacitor allocation solution is found for the system of feeders fed through their transformer and not for any individual feeder. The main advantages due to capacitor installation, such as system capacity release and reduction of overall...

This paper presents an optimization algorithm for simultaneous improvement of power quality (PQ), optimal placement and sizing of fixed capacitor banks in radial distribution networks in the presence of voltage and current harmonics. The algorithm is based on particle swarm optimization (PSO). The objective function includes the cost of power losses, energy losses and those of the capacitor ban...

This work proposes a two-stage immune algorithm that embeds the compromise programming to perform multi-objective optimal capacitor placement. A new problem formulation model that involves fuzzy sets to reflect the imprecise nature of objectives and incorporates multiple planning requirements is presented. The proposed approach finds a set of noninferior (Pareto) solutions rather than any singl...

Optimal capacitor allocation in distribution systems has been studied for a long times. It is an optimization problem which has an objective to define the optimal sizes and locations ofcapacitors to be installed.This paper presents a new methodology using particle swarm optimization (PSO) Algorithm for the placement of capacitors on the distribution systems to reduce the power losses and to imp...

<span lang="EN-US">Voltage stability represents one of the main issues in electrical power system. Under voltage load shedding (UVLS) has long been regarded as most successful techniques to prevent collapse. However, ordinary schemes do not consider different models and decreasing ‎economic cost that resulted from disconnection, so dual with reactive compensation are needed. Usually loads...

Optimal capacitor placement and network reconfiguration are well-known methods to minimize losses, enhance reliability, improve the voltage profile of electric distribution networks (EDNs). Distribution (DNR) consists altering system topology by changing states ties sectionalizing switches, while optimal capacitors (OPCAs) involves sizing finding location banks within for reactive power control...

-In this paper, multi-objective optimal placement (MOOP) of multi-type flexible AC transmission systems (FACTS) devices for Thailand power system is proposed. Four types of FACTS devices are used: thyristor-controlled series capacitor (TCSC), thyristor-controlled phase shifter (TCPS), unified power flow controller (UPFC), and static var compensator (SVC). The problem is decomposed into the opti...
