1) What is a smart grid
- a power system that can incorporate millions of sensrs all connectied through an adcanced communication and data system.
- provide real time analysis

2) Benefits of grid
- do not rely on conusmer participation
- increased efficiency and optomozation
- save up to 25% of energy related carbon

3) Smart grid is a foundation technology

Hu Xue Hao
- high wuality power will play a larger and important role going forward. china is facing a lot of power challenges
- Smart grid is new and contains a lot of potentially important technologies

“In China, smart Grid has no clear definition and has not been systematically studied. only in the beginning of research”

2 principal points
1) power grid in china keeps same pace as GDP – 10%+ growth 2) the emphasis of development is manly on transmission system

6 geographic segments in grid. all are connected to each other
- more than 500 stations in China. mostly 500KVVA

focus on tech relative to distribution network
- renovation and improvement
- advanced metering infrastructure
- distribution generation application with small generaion units
- batteries

Different points
1) West is focused on distribution network/ China is on transmission grid
2) USA/ UK DG burning gas is expanding fast… china is short of fuel, so slow
3) USA/ EU – PV is mainly rooftop. china is water

Bai Ciao Min
China is very different than US. In 1998, there was a renovation of the network that has good equipment, but does not match to smart grid.

Some difference
- currently network can meet 50% of population
- infrastructure is being funded by state
- needs of rural is scatered and usage difference, so equipment requirements are very different

Key features of power grid
- focused on large scale transmission – reasearch is focused towards that goal -measurement, dispatch, management, etc
- system is fragile – a major incident could have big consequences
