Reliable operation of distributed internet things (IoT) devices is essential for supporting two-way interaction between energy flow and information in a distribution power grid. Traditional reliability evaluation methods suffer from several challenges including complex indicator selection inadaptability fixed weights with actual requirements. In this paper, we first establish multilevel system,...

The aim of this paper is to estimate a single reliability system (R = P, Z > W) with strength subjected stress W in stress-strength model that follows power Rayleigh distribution. It proposes, generates and examines eight methods techniques for estimating distribution parameters functions. These are the maximum likelihood estimation(MLE), exact moment estimation (EMME), percentile (PE), leas...

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

Power distribution system in the country is characterized by high power losses, poor reliability of supply, frequent equipment burnouts etc. The traditional approach in electric power generation is to have centralized plants distributing electricity through an extensive transmission & distribution network. Distribution generation (dg) provides electric power at a site closer to the customer, el...

Abstract – This paper gives a brief overview of production facilities from renewable energy sources which especially influence the power system with variable production. The paper describes some basic ways of connection and technical data relevant for the design of production plants, as well as the most important influences on the power system, especially with respect to the following: voltage,...
