provide meet user requirements of power quality in the 21st century, allow all sorts of different

power generation in the form of access, start the electric power market and asset optimization run

efficiently.

application of Internet of things, and published in the journal of computer smart grid information

system architecture research is carried on the detailed discussion on this, and the architecture of

the smart grid information system are analyzed.

The market share

The establishment of the smart grid is a huge historical present many complicated smart
