Abstract

The invention relates to a power grid operation trend estimation method and system. The method comprises the steps: selecting similar sections of a current section from historical sections; estimatinga power grid operation trend by utilizing the characteristic data of the current section and the tide data of the similar section. According to the invention, the power grid operation trend estimation method provided by the invention is strong in convergence performance, high in calculation accuracy and simple in calculation process, and can effectively improve the calculation efficiency of the power grid operation trend.

Description

technical field [0001] The invention relates to the field of electric power system and its automation, in particular to a method and system for estimating the running trend of a power grid. Background technique [0002] With the rapid upgrading of the support technology of the smart grid dispatching support system, its product features have gradually changed to a software service model, in which the future state power flow calculation service is applied to specific power grid analysis scenarios, and forecasting the operation trend of the power grid is an indispensable one. link. [0003] The future state power flow calculation service should support the requirements of the power grid for the initialization section of the future operation mode, and support the dispatching plan and security check for the requirements of the future operation mode section of the power grid with accurate active power and reactive power and reasonable voltage. [0004] The future state power flow...
