Distributed generation (DG) has been widely used in distribution network to reduce the energy losses, improve voltage profile and system reliability, etc.  The location and capacity of DG units can influence on probability of protection mal-operation in distribution networks. In this paper, a novel model for DG planning is proposed to find the optimum DG location and sizing in radial distr...

Complex power loss minimization is an important aspect of modern distribution systems. Complex power loss minimization leads to capacity reduction with improved voltage profile besides active power loss minimization under certain justified assumptions. This paper presents a simple, efficient and direct method for minimum complex power loss radial feeder reconfiguration in response to changing o...

Distribution systems form an important link between the bulk energy sources and consumers. About 80% of the interruptions that the consumers experience occur due to failures in distribution systems. This is due to radial nature of these links and scarcity of protection devices. Therefore, reliability assessment is essential to identify weaker areas needing reinforcements and understand, how cha...

Distribution networks transport electric energy to the end user from distribution substations. Power utilities are looking for improved power delivery performance. The performance of the delivery system is measured by the power loss of the system. The increase in power loss increases the operating cost of the distribution system. This paper presents an algorithm to minimizing the power loss of ...

Distribution systems can be operated in multiple configurations since they are possible combinations of radial and loop feeders. Each configuration leads to its own power losses and reliability level of supplying electric energy to customers. In order to obtain the optimal configuration of power networks, their reconfiguration is formulated as a complex optimization problem with different objec...

This study investigates the time-dependent long-term creep strain in a composite cylinder made of glass/vinylester with a unidirectional ply. The cylinder is subjected to an internal pressure and the boundary condition is free–free and acts as thermal insulation. The classical lamination theory (CLT) is used to derive the governing equations as a second-order equation to determine the radial, c...

This paper presents a new method to detect high impedance faults in radial distribution systems. Magnitudes of third and fifth harmonic components of voltages and currents are used as a feature vector for fault discrimination. The proposed methodology uses a learning vector quantization (LVQ) neural network as a classifier for identifying high impedance arc-type faults. The network learns from ...

Automatic generation of distribution system diagrams is an important aid for the distribution system planner and operator alike for easy visualization of the system. Since a Radial distribution system has a tree structure, what we need to develop is essentially a tree drawing algorithm. In addition,we aim to generate a distribution system graph that is aesthetically pleasing. We define a new se...
