Abstract

The invention provides an online stability evaluation index system of an electric power system. The online stability evaluation index system comprises an online data integration module, a power grid operating state index classification and evaluation module, a power grid variation trend index customization and calculation module, a power grid variation trend index display module and a power grid variation trend decision-making aid module. On the basis of an online integration method of basic data, index classification and calculation are carried out accompanied by index display, and thus a reliable and reasonable basis is provided for aiding decision making of future trend variation of the power grid. Algorithm development, induction, summarization and classification are carried out on indexes reflecting the future operating state of the power grid in all aspects, and the future operating state of the power grid is clearly displayed. What needs to be protected mainly includes the design framework and the function content of an index system, an index classification method and a method adopted for a platform index customization tool and a formula parser.

Description

technical field [0001] The invention belongs to the field of grid stability analysis, and in particular relates to an online stability evaluation index system of a power system. Background technique [0002] The interconnection of modern power grids and the expansion of the grid-connected scale of intermittent new energy power sources, as well as the application of various new power electronic components, make the operating conditions of the power grid more complex, and the stability mechanism and evaluation methods of the unified power grid have not yet been studied in depth. In terms of forecasting the future situation of the power grid, it only stays in the form of using the future planned flow (power generation, load, maintenance, etc.), and it still belongs to the research method combining "prediction method and traditional analysis". According to the change characteristics of the dynamic response trajectory of the power grid, the quantitative estimation methods and ind...
