SMART GRID
Abstract--The Smart Grid is the integration of Electrical & Digital Technologies, Information and communication which facilitates integration of business processes and systems to yield real measurable value across the power delivery chain. It is an intelligent future electricity system that connects all supply, grid and demand elements through a communication system. Smart grid delivers electricity to consumers using two-way digital technology that enable the efficient management of consumers, efficient use of the grid to identify and correct supply- demand imbalances. Smart Grid solutions enable utilities to increase energy productivity and power reliability while allowing the customers to manage the usage and costs through real time information exchange. It impacts all the components of the power system like Generation, Transmission and Distribution.

1.Introduction

According to a definition by the Department of Energy (DOE), the "smart grid" generally refers to a class of technology people are using to bring utility electricity delivery systems into the 21st century, using computer-based remote control and automation. These systems are made possible by two-way communication technology and computer processing that has been used for decades in other industries. They are beginning to be used on electricity networks, from the power plants and wind farms all the way to the consumers of electricity in homes and businesses.
The “grid” amounts to the networks that carry electricity from the plants where it is generated to consumers. The grid includes wires, substations, transformers, switches and much more. And the Smart Grid is a collection of energy control and monitoring devices, software, networking and Communications infrastructure that are installed in homes, businesses, and throughout the electricity distribution grid. smart grid means “computerizing” the electric utility grid. Each device on the network can be

    Additionally, this electrical smart-grid allows customers to monitor their individual power use reducing household usage by up to 30% in some cases, thereby enhancing customer satisfaction. Although this may lead to a decrease in revenue for Xcel Energy, the smart-grid system enables integration of renewable generation, an increase in overall system efficiency, a more robust electrical system and an ability to recover under-utilized and wasted energy. We can’t say for sure, but this may actually benefit Xcel Energy in the long-run as they will recover lost revenue through their decreased operational costs using the smart-grid electrical system.…

    The U3300 electronic meter is Western Power’s trial meter as part of a trial of the use of smart meters, also known as advanced metering infrastructure (AMI). It is a three-phase meter for direct metering installations with a capacity of up to 100 amperes. This smart meter is capable of two-way communication between the meter and Western Power. The smart meter will also provide improved accuracy of meter readings, early detection of power quality issues, remote disconnection of power and improved monitoring of power outages to assist maintenance crews in reducing restoration times.…

    Electric current then it runs through the power lines to the substation transformer where the pressure is lowered to between 2000 and 13000 volts. Then the electricity is taken through the lines to a pole transformer and a transformer box if underground and the pressure is lowered again to between 120 240 volts. Then from this side on the electricity comes into our homes through a service box and then the meter is located which can measure how much electricity we use in our homes and the wires take the electricity around our homes powering the lights and all our other…

    The regular electricity infrastructure in the US provides power to consumers, but does not information on how the consumers are using the energy when the smart grids are. It uses digital technology to save energy, reduce costs, and increase reliability and transparency. Without the smart grids, the electricity infrastructure is outdated and inefficient.…

    Electricians are the men and women that bring electricity into businesses, factories, and homes. If there's wiring, fuses, and other electrical components in a facility, chances are it was installed by an electrician (wyotech.edu). Electricians normally start their day by reading blueprints. These are technical diagrams that reveal the locations of outlets, loaded centres, panel boards and other electrical related components. For safety, electricians follow the National Electrical Code, and State and local building codes.…

    The advantages and disadvantages of carbon sequestration depend in large part on the methods used. Capturing CO2 gas and piping it underground is, as another answerer suggested, risky and probably inefficient. But other methods may hold more promise. For example, using algae to sequester carbon, then burying the algae, eliminates the problem of the tendency of a gas to escape confinement. The major advantage of employing some kind of carbon sequestration technology is that it can, in effect, reverse some fraction of our bad habits with regard to CO2 emissions. Unless we find some way to sequester massive quantities of carbon more cheaply than the difference between fossil fuel technologies and renewable energy technologies, it won't give us carte blanche to keep using fossil fuel, but it can help reverse some of the past damage and/or help us ease the transition to newer tech.…
