Abstract

The invention provides a reactive power optimization method for a power distribution network, a reactive power optimization device for a power distribution network, computer equipment and a readable storage medium. The method comprises the following steps that: 1, the reactive power optimization model of the power distribution network system is obtained; the network loss optimization function of the a power distribution network system and the action loss optimization function of discrete reactive power equipment are converted to a Markov decision process corresponding to the reactive power optimization of the power distribution network according to the reactive power optimization model; and with a state value adopted as an objective, the Markov decision process is solved, the configurationinformation of the discrete reactive power regulation equipment is obtained, and the power distribution network system is configured according to the configuration information, and the reactive poweroptimization of the power distribution network system is realized. With the reactive power optimization method for the power distribution network, the reactive power optimization device for the powerdistribution network, the computer equipment and the readable storage medium of the invention, the low perceptibility of a low-voltage-level power grid is fully considered, worry-free optimization can be realized without modeling the power flow state of the power distribution network; and therefore, the network loss and capacitor actions of the power distribution network system are effectively reduced, so that the economical efficiency of the operation of the power distribution network system is improved.

Description

technical field [0001] The present application relates to the technical field of electric power system control, in particular to a reactive power optimization method, device, computer equipment and readable storage medium of a distribution network. Background technique [0002] In recent years, in order to cope with energy crisis and environmental pollution, countries around the world are also vigorously encouraging the development of distributed new energy while promoting the utilization of centralized new energy. At the same time, with the gradual increase of the penetration rate of these distributed energy sources in the distribution network, the reactive power optimization of the distribution network after its grid connection has brought great difficulties. [0003] To solve the reactive power optimization problem in traditional technology, the network loss of the distribution network system is usually used as the optimization target, and the action sequence of the discr...
