“…This is consistent since it is more economic to implement branches from one or two phases of the trunk circuit than installing three-phase circuits directly to the end users [5]. The load unbalance in the power distribution systems creates undesirable scenarios, such as current increase at some of the phases of the system, current through the neutral wire, and over-voltage on the least-loaded phases [6] which, consequently, will increase power loss, an inappropriate operation for protection and creating negative effects on power quality [6].…”

This article discusses the problem of minimizing power loss in unbalanced distribution systems through phase-balancing. This problem is represented by a mixed-integer nonlinear-programming mathematical model, which is solved by applying a discretely encoded Vortex Search Algorithm (DVSA). The numerical results of simulations performed in IEEE 8-, 25-, and 37-node test systems demonstrate the applicability of the proposed methodology when compared with the classical Cuh & Beasley genetic algorithm. In addition, the computation times required by the algorithm to find the optimal solution are in the order of seconds, which makes the proposed DVSA a robust, reliable, and efficient tool. All computational implementations have been developed in the MATLAB® programming environment, and all the results have been evaluated in DigSILENT© software to verify the effectiveness and the proposed three-phase unbalanced power-flow method.

“…WCA was also incorporated in the article [151], where the authors suggested two load power factor models to minify feeder losses and voltage profile enhancement. GA interfaced with COM model has developed for optimal phase reconfiguration and SCBs placement [152]. In [153], a Hybrid WIPSO-GSA algorithm has been proposed in distribution systems considering feeder failure rate.…”

The main goal of power utilities is to supply reliable and quality power to the end-users and fulfill their total demands at all possible locations. Most of the loads are connected in the distribution systems are inductive. The excessive reactive power demand over the distribution network causes tremendous reactive power losses and changes the voltage profile, hence the system's reliability. Shunt Capacitor Bank (SCB) is widely used in the distribution system for reactive power support, voltage profile, and system performance improvement. But there are some challenges to employ SCB in the distribution network; among them, ensuring the most optimum location and size is a big challenge to get the maximum benefits. Some existing techniques showed better loss reduction but needed either larger SCBs sizes or cause improper node voltage. In this research study, the first section provides an extensive literature review of optimal SCBs placement and sizing. Later on, a new technique called Combinatorial Method has been developed for sizing and sitting of optimal Shunt Capacitors to reduce the distribution loss significantly. The developed method was tested for different case studies using Indian practical 22-bus and IEEE-69-bus network. The results were compared with DSA, Fuzzy GA, and TLBO method and found better distribution feeder loss minimization and voltage profile improvement.

“…The paper [14] focuses on introducing the coordinated voltage control technique for solving a voltage quality problem. Also, there is a large number of already developed means for increasing PSR and PQ, for example, systems for regulating electrical power quality parameters (for example, adaptive automatic voltage regulation [15]), transformer substation automation systems (Automatic Transfer Switches (ATS), automatic circuit reclosers (ACR) [16], under-frequency load shedding (UFLS), buses' load balancing [17]), systems of automatic regulation (compensation) of reactive power [18], [19]. At the same time, the implementation of these means as well as using methods for increasing PSR and PQ, including ones mentioned above, requires monitoring the electrical network parameters in order to accurately and quickly respond to any changes in a power supply system [20].…”

The need for monitoring the electrical network parameters is identified to use methods and means to improve power supply reliability and power quality. The article lists the exiting sensors for monitoring electrical parameters and substantiates the necessity of monitoring the parameters at both sides of switching devices. In the paper, there is basic information on the structure, operation and capabilities of the monitoring system for power supply reliability and power quality. A functional electrical circuit of the device for monitoring the number and duration of power outages and voltage deviations is proposed for monitoring the parameters at both sides of switching devices. An algorithm for the device operation has also been developed, which allows detecting the main emergency modes in the consumer's internal network. The article also describes laboratory tests of a prototype of the device for monitoring the number and duration of power outages and voltage deviations, which is based on the Arduino NANO V3 ATmega 328 microprocessor. INDEX TERMS power supply system efficiency, power supply reliability, power quality, power supply restoration time, power quality inconsistency time, monitoring system, Arduino prototype, laboratory tests.
