Ǿ The development and implementation of a smart grid for power
supply is one of the pressing issues in modern energy economy,
given high national priority and massive investments, although
the entire subject is still in its infancy stage.
Ǿ The smart grid delivers electricity from producers to consumers
using two-way digital technology, and allows control of
appliances in the consumers' houses and of machines in factories
to save energy, while reducing costs and increasing reliability and
Ǿ In principle, the smart grid is an upgrade of the common
electricity grids that operate mostly to provide one-way power
from several major power plants to a large number of Consumers.
Ǿ The smart grid could be at the city level, integrate into a national
grid, or at the plant level, integrated into the urban grid ready for
