The problem of capacitor allocation for loss reduction in electric distribution systems has been extensively researched over the past several decades. This paper describes the evolution of the research and provides an evaluation of the practicality and accuracy of the capacitor placement algorithms in the literature. The intent of this paper is not to provide a complete survey of all the litera...

This paper provides a new approach in decision making process for shunt capacitor placement in distribution networks. The main core of the evaluation process is a multi-objective framework to allocate the capacitor banks. The power loss and the total harmonic distortion (THD) are the objective functions of the system under study in a long-term planning horizon. In order to select the executive ...

Topology for reactive power compensation of dynamic load in closed loop is presented. The scheme consists of Thyristor Binary Switched Capacitor (TBSC) banks and a Thyristor Controlled Reactor (TCR). TBSC is based on a chain of Thyristor Switched Capacitor (TSC) banks arranged in binary sequential manner. TCR capacity is chosen to be smallest of TBSC step size. A transient free switching of TBS...

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...

There is an increasing interest in renewable and green energy sources and the integration of Distributed Generation DG into the power grid system. The problem of optimal capacitor allocation in electric distribution systems involves maximizing energy utilization, feeder loss reduction, and power factor correction. The feeder loss can be separated into two parts based on the active and reactive ...

This paper deals with the voltage stability problem associated with radial distribution networks. Two load models are studied: the full load flow model (FLFM) and the equivalent generic single-line model (EGSLM). Optimization is then carried out to find the optimal capacitor size that minimizes some costing function, and finally several capacitor placement techniques are studied.

This paper reports concerns of capacitor placement in power distribution systems in the locality of a dynamic voltage restorer (DVR). A feedback controlled simulation model of an actual DVR is developed to perform case studies. Cogency of this model is established by associat ing the waveforms from the model with field measurements. Issues relating to expansion of a DVR in the locality of power...
