Distributed generator (DG) placement in distribution system is one of the important tasks for better operation of distribution system. Distribution system has high r/x ratio and high operating current resulting into higher power loss and higher voltage drop. The main objective of this paper is to minimize the active power loss and to improve voltage profile of overall system by optimal sizing a...

The main goal of this study is the use of Lyapunov’s stability theory to a three-phase four-wire shunt active power filter (SAPF), since this method has been applied effectively to other areas of converter. The dynamic model of the SAPF is first established, after that, a combination of fuzzy tracking control and Lyapunov function is suggested in order to impose a desired transient waveform on ...

This manuscript explores feeder reconfiguration in distribution networks and presents an efficient method to optimize the radial distribution system by means of simultaneous reconfiguration. Network Reconfiguration of radial distribution system is a significant way of altering the power flow through the lines. This assessment presents a modern method to solve the network reconfiguration problem...

This work introduces the weighted radial basis collocation method for boundary value problems. We first show that the employment of least-squares functional with quadrature rules constitutes an approximation of the direct collocation method. Standard radial basis collocation method, however, yields a larger solution error near boundaries. The residuals in the least-squares functional associated...

An additional voltage stage of 0,95 kV allows to reduce losses for the transmission electricity in long-distance distribution networks with sufficient transmitted power. A pilot project such network has been implemented. However, practice using this class is not widespread at present. As an energy-saving means networks, it possible use a load equalization device operating on principle redistrib...

The modelling of a three-phase four-leg four-wire grid-forming inverter in low voltage distribution system 18-bus European Cigré under unbalanced conditions an autonomous network is presented. case study has two types inverters control strategy: (i) to supply all the demand interval intentional interruption and (ii) grid-following integrate photovoltaic renewable energy resources into power sys...

This paper presents a novel method for load flow analysis in radially operated 3-phase distribution networks without solving the well-known conventional load flow equations. The method can be applied for distribution systems in which the loads are unbalanced. As the size of matrix used is very small compared to those in conventional methods, the amount of memory used is very small, the speed is...
