Abstract
A computer algorithm for optimal voltage controlwith voltage regulators, suitable for large radial distribution networksis given in this paper. An objective function concerning thetotal cost of the voltage regulators (investment and maintenancecost) as well as the cost of losses of the examined networks is developedand constitutes the base of the algorithm. This algorithmmakes the initial selection, installation and tap setting of the voltageregulators, which provide a smooth voltage profile along the network,utilizing former ....etc

The Challenge

-Portland’s Bureau of Water Supply provides water to Burlington, just northwest of the city.
-A few residences in the higher elevations of Burlington have experienced very low water pressures, prompting the Bureau to ask the students to investigate possible solutions.

Problem Definition

•Low water pressures:
–Are an inconvenience
–Violate Oregon State standards
–Are a potential health risk
•Investigate:
–Reasons for low pressures
–Potential Soluti ....etc

LOADABILITY ASPECTS FOR MEDIUM VOLTAGE
DISTRIBUTION NETWORKS WITH INTEGRATION OF
DECENTRALIZED GENERATION
ABSTRACT
Decentralized Generation (DG) is an emerging concept in the electricity sector; its
integration into distribution networks may have a significant impact on different
technical aspects. The main aim of this paper is the investigation of the impact of
DG on the loadability of medium voltage distribution networks. The loadability is
evaluated in two aspects, the maximum loading according to the voltage limit ....etc

Abstract:
Partial discharge (P.D.) in micro cavities in the insulation of H.V. power cables drastically affect the performance, the field distribution and hence the rating of these cables. It is well known that, P.D. deteriorates power cables and lead to its complete failure. This has adverse effects on the reliability and maintainability of power supply, which affects directly the production of industrial factories. In this work a study and investigation of the effect of partial discharges in cavit ....etc

ABSTRACT
In this paper, the convergence ability of Distribution Systems Power Flow Algorithms, which are widely used for distribution systems analysis, is compared with different voltage-dependent load models. The convergence ability of methods are also evaluated for different tolerance values, voltage levels, loading conditions and R/X ratios, under the wide range exponents of loads. Results show that Ratio-Flow method is preferable from other ....etc

1. DISTRIBUTION SYSTEM

1.1 General description of Distribution System:

Distribution system is that part of the electric power system which connects the high voltage transmission network to the low voltage consumer service point

In any distribution system the power is distributed to various uses through feeders, distributors and service mains. Feeders are conductors of large current carrying capacity which carry the current in bulk to the feeding points. ....etc
