Smart Grid
What is Smart Grid???
A smart grid is a modernized ELECTRICAL GRID that
uses information and communications technology to
gather and act on information, such as information
about the behaviors of suppliers and consumers, in an
automated fashion to improve the efficiency, reliability,
economics, and sustainability of the production and
distribution of electricity.[
What is electrical grid?
An electrical grid is an interconnected network
for delivering electricity from suppliers to
consumers. It consists of generating stations that
produce electrical power, high-voltage
transmission lines that carry power from distant
sources to demand centers, and distribution lines
that connect individual customers.
In the 20th century power grids originated as local grids that grew
over time, and were eventually interconnected for economic and
reliability reasons. By the 1960s, the electric grids of developed
countries had become very large, mature and highly
interconnected, with thousands of 'central' generation power
stations delivering power to major load centres via high capacity
power lines which were then branched and divided to provide
power to smaller industrial and domestic users over the entire supply
area. The topology of the 1960s grid was a result of the strong
economies of scale of the current generation technology: large
coal-, gas- and oil-fired power stations in the 1 GW (1000 MW) to 3
GW scale are still found to be cost-effective, due to efficiencyboosting features that can be cost effectively added only when the
stations become very large.
