With the construction of the new power system

in order to better achieve the observability

measurability and state estimation of the new power system

the electric field sensor will present a massive distribution trend. The quantum sensor can realize the traceability of physical quantities to basic physical constants

and it has many advantages such as high accuracy

wide frequency domain

and remote calibration. The measurement field will not be disturbed

and it is poised to see significantly wider application in power systems in the future. The Rydberg electric field measurement technology based on electromagnetically induced transparency (EIT) and Stark effect has great potentials in measurement because its Rydberg atoms have many unique properties compared with ordinary ground state atoms

such as longer energy level lifetime

larger polarizability and electric dipole moment. This paper focuses on the Rydberg electric field measurement technology

briefly introduces the principle of Rydberg electric field measurement based on EIT and Stark effect

introduces the uncertainty evaluation and the development of the measurement method by frequency band division

and puts forward the prospects in the two major breakthrough direction of the application of Rydberg electric field measurement technology in the power system and the application scenarios of Rydberg electric field sensors in the new power system. The study can provide certain reference values for the comprehensive practical application of quantum precision measurement technology in the power system.
