Building ubiquitous power internet of things (UPIoT) is a necessary means to achieve the goal of energy transformation. Starting from the development history and problems of power system

the significance of UPIoT was discussed

and the implementation strategies and possible problems were put forward. In order to realize the energy transformation

the installed capacity of renewable energy such as wind

photovoltaic (PV) and so on is increasing. The randomness of these sources of energy causes tremendous pressure on the power balance of power systems

sometimes having to abandon part of electricity from wind farms and PV. In order to maintain the stable operation of power system and improve the utilization rate of wind power and photoelectricity

it is necessary to control controllable load and decentralized generation. Therefore

it is necessary to connect controllable load and decentralized power generation with the internet to form a UPIoT. Conventional power plants

large-scale wind farms

PV stations have been connected to dispatching center

and can be directly controlled. Therefore

the main task of UPIoT is to connect load and distributed generation

especially controllable load. Electric vehicles are the easiest controllable loads

followed by water heaters

electric boilers and air conditioners. Utilizing the UPIoT

coordinated control of wind power and PV

controllable load

decentralized power generation

etc.

can improve the utilization rate of wind power and PV

and achieve the goal of energy transformation.
