Cloud-edge cooperative voltage reactive intelligent control system and control method

Abstract

The invention discloses a cloud-edge cooperative voltage reactive intelligent control system, which comprises a voltage reactive control layer based on cloud-side cooperative computing and a voltage reactive control layer based on station-side edge computing, and realizes reactive control of first harmonic control and then reactive compensation, first local-station self healing and then cloud-sideoptimization. The invention further discloses a new voltage reactive power control technical scheme based on two-stage optimization. According to the first-stage optimization scheme, harmonic controland reactive power compensation are carried out in sequence, and the problem that mutual influence exists between harmonic control and reactive voltage is solved; according to the second-stage optimization scheme, local-station self healing and cloud optimization are carried out in sequence, the contradiction between control real-time control and whole-network cooperative control of the voltage reactive power is solved, so that the difficult problem that voltage reactive power control cannot be always in an optimized operation state for a long time in the field is solved, the effect from quantitative change to qualitative change is achieved, the requirements of energy conservation and emission reduction of terminal users are met to the maximum extent, and enterprises, social and economicbenefits and social benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to a cloud-edge cooperative voltage and reactive power intelligent control system and a control method. Background technique [0002] In order to realize the economic operation of the power grid of end users, it is required that the network loss of the power grid of end users be minimized, realize the goal of energy saving and emission reduction, and improve the economic and social benefits of enterprises and society. [0003] To achieve the minimum network loss in grid operation, it is necessary to control the grid voltage and reactive power to the minimum. Voltage reactive power is used for the exchange of electric and magnetic fields within a circuit, and is used to establish and maintain the electric power of a magnetic field in electrical equipment. Excessive grid voltage and reactive power will have certain adverse effects on power supply and consu...
