China's power grid

1. Displayed content:

The slider on the mobile multimedia console allows viewers to see the development history of China's power grid over time, as well as future development trends, thereby learning more about upcoming and concerning issues such as rapidly growing electricity demand, concerns about power system reliability and energy security, environmental degradation and climate change, and how to face these issues in the future.

Scientific principles (demonstrated scientific principles or advanced technologies):

China's power grid has gone through three stages: initial construction, large-scale development, and the formation of regional power grid interconnection. The power grid function has evolved from simple power transmission to optimized allocation of power resources between cities, provinces, and even across large regions. In this process, the development of large power sources and the West East power transmission jointly promoted the development of the large power grid, but when the system reaches a certain scale, the marginal effect of the large power grid will gradually decrease. The protagonist of future power grid construction will gradually evolve from the transmission network to the distribution network.

2. The main purpose of the presentation is:

Enable the audience to understand the specific use cases of Ohm's Law in real life, and gain insights into the development and progress of China's power grid
