This paper presents a simple approach for load flow analysis of a radial distribution network. The proposed approach utilizes forward and backward sweep algorithm based on Kirchoff’s current law (KCL) and Kirchoff’s voltage law (KVL) for evaluating the node voltages iteratively. In this approach, computation of branch current depends only on the current injected at the neighbouring node and the...

This paper proposes a method for real-time control of capacitors in a distribution system to reduce the total power loss and to improve the voltage profile. Traditionally, this problem of optimal capacitor switching has been solved through various optimizations techniques. However, as the time taken by these traditional optimization methods are quite significant, these methods may not be much s...

in studies done on porous burner, generally burners with axial flow are considered. in this paper, porous burners with radial and axial flow have been modeled numerically and results of radial and axial porous burners with equal fuel consumptions are compared. the mechanism used in combustion phenomenon is 15 stage mechanisms which predict the pollutions production precisely. the results show a...

This paper proposes the application of Direct Approach algorithm for feeder routing of radial distribution system. For which a complete network of available routes is considered and the optimization goal is to find the routes that provide the minimum number of energizing nodes for existing network and load flow analysis for the same network. The feasibility of proposed algorithm is applied on 2...

Direct displacement based design (DDBD) is a conceptual framework that directly design a structure to achieve an expected performance level under specified seismic intensity. In this study, two important issues relevant to torsional response of mass eccentric 8-story RC building designed with DDBD approach are investigated. These issues are including the effects of unbalanced mass distribution ...

Simulations have shown that while semi-definite relaxations of AC optimal power flow (AC-OPF) on three-phase radial networks with only wye connections tend to be exact, the presence delta seem render them inexact. This article shows such inexactness originates from non-uniqueness relaxation solutions and numerical errors amplified by non-uniqueness. finding motivates two algorithms recover exac...

The molecular genetic mechanisms underlying abaxial-adaxial polarity in plants have been studied as a property of lateral and flattened organs, such as leaves. In leaves, laminar expansion occurs as a result of balanced abaxial-adaxial gene expression. Over- or under- expression of either abaxializing or adaxializing genes inhibits laminar growth, resulting in a mutant radialized phenotype. Her...

In this study, a new methodology is proposed to perform optimal selection of conductors in three-phase distribution networks through discrete version the metaheuristic method vortex search. To represent problem, single-objective mathematical model with mixed-integer nonlinear programming (MINLP) structure used. As an objective function, minimization investment costs together technical losses ne...
