Recently, smart grids have been considered as one of the vital elements in upgrading current power systems to a system with more reliability and efficiency. Distributed generation is necessary for most of these new networks. Indeed, in all cases that DGs are used in distribution systems, protection coordination failures may occur in multiple configurations of smart grids using DGs. In different...

The design of robust and area efficient power distribution networks for high speed, high complexity integrated circuits has become a challenging task. The integrity of the high frequency signals depends upon the impedance characteristics of the on-chip power distribution networks. The electrical characteristics of these multi-layer power distribution grids and the relevant design implications a...

2 the output of " utility scale " DERs (> one megawatt). In addition, existing industry standards define advanced functions for DER only at the individual device level, and lack the more aggregated, feeder-level representations that are needed for enterprise integration. This white paper describes ongoing research at the Electric Power Research Institute that is exploring Various ways in which ...

The Weibull distribution is widely employed in several areas of engineering because it is an extremely flexible distribution with different shapes. Moreover, it can include characteristics of several other distributions. However, successful usage of Weibull distribution depends on estimation accuracy for three parameters of scale, shape and location. This issue shifts the attentions to the requ...

The Smart Grid concept introduces an updated architecture and new elements to the traditional power grid. As a result, existing survivability schemes that have been designed with a centralized architecture in mind are either inefficient or no longer applicable. In this paper, we review several solutions that have been suggested in the literature in order to ensure the proper operation of the po...

Smart Grid, as an energy-based Cyber-Physical Sys­ tem (CPS), is a new type of power grid that will provide reliable, secure, and efficient energy transmission and distribution. As the quality of assurance of monitoring data is essential to smart grid, in this talk we will first present two dangerous false data injection attacks, which target the state estimation and energy distribution in smar...

The efficient exploitation of worldwide distributed storage and computing resources available in the grids require a robust, transparent and fast deployment of experiment specific software. The approach followed by the CMS experiment at CERN in order to enable Monte-Carlo simulations, data analysis and software development in an international collaboration is presented. The current status and f...

Voltage control is one of the imperative issues in the smart distribution control system. While traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. With using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...
