22 Facts About Smart grid

Smart grid is an electrical grid which includes a variety of operation and energy measures including:.

Smart grid policy is organized in Europe as Smart Grid European Technology Platform.

Roll-out of smart grid technology implies a fundamental re-engineering of the electricity services industry, although typical usage of the term is focused on the technical infrastructure.

At that time, the Smart grid was a centralized unidirectional system of electric power transmission, electricity distribution, and demand-driven control.

The topology of the 1960s Smart grid was a result of the strong economies of scale: large coal-, gas- and oil-fired power stations in the 1 GW to 3 GW scale are still found to be cost-effective, due to efficiency-boosting features that can be cost-effective only when the stations become very large.

The metering capabilities of the 1960s Smart grid meant technological limitations on the degree to which price signals could be propagated through the system.

The relatively low utilisation of these peaking generators, together with the necessary redundancy in the electricity Smart grid, resulting in high costs to the electricity companies, which were passed on in the form of increased tariffs.

Finally, growing concern over terrorist attacks in some countries has led to calls for a more robust energy Smart grid that is less dependent on centralised power stations that were perceived to be potential attack targets.

Smart grid technologies emerged from earlier attempts at using electronic control, metering, and monitoring.

Smart grid meters add continuous communications so that monitoring can be done in real-time, and can be used as a gateway to demand response-aware devices and "smart sockets" in the home.

Smart grid represents the full suite of current and proposed responses to the challenges of electricity supply.

Smart grid makes use of technologies such as state estimation, that improve fault detection and allow self-healing of the network without the intervention of technicians.

Smart grid technology is a necessary condition for very large amounts of renewable electricity on the grid for this reason.

Smart grid allows for systematic communication between suppliers and consumers, and permits both the suppliers and the consumers to be more flexible and sophisticated in their operational strategies.

Currently, power Smart grid systems have varying degrees of communication within control systems for their high-value assets, such as in generating plants, transmission lines, substations, and major energy users.

Bulk of smart grid technologies are already used in other applications such as manufacturing and telecommunications and are being adapted for use in grid operations.

Smart grid provides IT-based solutions which the traditional power grid is lacking.

The Roadmap outlines the key issues and challenges for modernizing the Smart grid and suggests paths that government and industry can take to build America's future electric delivery system.

The increased efficiency and reliability of the smart grid is expected to save consumers money and help reduce CO2 emissions.

Additionally, infrastructure which relies on the electric Smart grid, including wastewater treatment facilities, the information technology sector, and communications systems could be impacted.

Some experts argue that the first step to increasing the cyber defenses of the smart electric grid is completing a comprehensive risk analysis of existing infrastructure, including research of software, hardware, and communication processes.

Incorporation of digital communications and computer infrastructure with the Smart grid's existing physical infrastructure poses challenges and inherent vulnerabilities.
