PRESENT AND FUTURE TRENDS
Present trend
indicates a shifting
away from the
dependence on the
direct use of fossil
fuels.
PRESENT AND FUTURE TRENDS
Transmission and distribution grids are aging and being stressed by
operational uncertainties and challenges never envisioned when they were
developed many decades ago.
A growing consensus in the power industry is to use smart grid technology to
answer the challenges.
A smart grid is characterized by the following attributes:
