Abstract

Embodiments of the invention disclose a power distribution network overload risk assessment method and apparatus. The method comprises the steps of obtaining historical change ranges of a running parameter and an environment parameter of a target primary device in a power distribution network; obtaining running data and environment data of the target primary device; and according to the historicalchange ranges of the running parameter and the environment parameter of the target primary device and the running data and the environment data of the target primary device, judging whether the powerdistribution network is overloaded or not. An assessment model is built based on the historical change ranges of the running parameter and the environment parameter of the target primary device of the power distribution network; the power distribution network is assessed based on the assessment model and the running data and the environment data, collected in real time, of the target primary device; and compared with the prior art, the assessment method and apparatus has the advantages of lowering modeling complexity and improving assessment efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of power grids, and in particular to a method and device for evaluating the overload risk of a distribution network. Background technique [0002] Photovoltaic power generation, as a form of power generation with the most economic development prospects in new energy sources, has gradually attracted the attention of various countries and has been widely developed and utilized. However, as large-scale photovoltaics are connected to the grid, their randomness, intermittency, and disturbance have brought great challenges to the safe operation of the power system, often causing accidents such as line overload and voltage over-limit. Risk control of line overload can achieve the purpose of reducing system risk, which is of great practical significance to the safety, stability and operation of the power system. [0003] However, in the process of implementing the embodiments of the presen...
