Breakthrough the Limit of New Energy Power Consumption with Ubiquitous Power Internet of Things

Building ubiquitous power internet of things (UPIoT) is a necessary means to achieve the goal of energy transition. Starting from the development history and problems of power system, the significance of UPIoT was discussed, the implementation strategies and possible problems were put forward. To realize the energy transition, 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, wind and PV power curtailment occur. In order to maintain the stable operation of power system and improve the utilization rate of wind power and PV, it is necessary to control controllable load and distributed generation. Therefore, it is needed to connect controllable load and distributed power generation with the 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 electric refrigerator, electric boilers and air conditioners. Utilizing the UPIoT, coordinated control of wind power and PV, controllable load, distributed power generation, etc., can improve the utilization rate of wind power and PV, and achieve the goal of energy transition.
