Dynamic modeling and optimal control method of electric energy statics on the basis of power grid topology

Abstract

The invention discloses a dynamic modeling and optimal control method of electric energy statics on the basis of power grid topology. Two big platforms, i.e. a power grid GIS (Geographic Information Service) platform and an electric energy metering system, are depended, a statistic body is taken as an object (such as a power generation enterprise and a provincial city), and the statistic body is surrounded as a center to look for the information of n switchgears, which are connected with a power grid system, of the statistic body, and a gateway metering device arranged on each switchgear through a power grid topology structure and data information to realize the dynamic modeling of the electric energy of the statistic body. The automation level of the electric energy statics is further improved, and the electric energy statics and modeling workload of a provincial power grid even a larger-scale power grid can be greatly lowered. Meanwhile, the real-time measurement data of a gateway is obtained to realize the electric energy real-time calculation by aiming at the statistic body, and a reliable method is provided for electricity purchasing and selling business data indexes.

Description

technical field [0001] The invention relates to the technical field of power system power grid electricity statistics and automation, in particular to a dynamic modeling and optimization control method for power statistics based on power grid topology. Background technique [0002] Electric energy is not only the core data index of the grid company's electricity purchase and sale business, but also the core statistical data that decision-makers are most concerned about; the statistics of electric energy can directly reflect the company's operating and management benefits. The real-time calculation and statistics of electric energy at all levels can directly present the development of the electricity purchase and sale business, grasp the changes in the company's electricity purchase and sale market in a timely manner, and provide better, faster, and more accurate macroeconomic information for the company's business decision-making adjustments. Basis for decision. [0003] St...

AI Technical Summary

Problems solved by technology

In the process of power grid construction and operation, the energy statistics of a statistical subject (province, provincial city or power generation company) usually need to involve many gateway metering devices; second, the modeling workload is heavy and the accuracy is low

Statistics on electric energy are already common, but most business systems are implemented through manual combing combined with static programming. And in the later stage, when the metering device is added or changed, the sorting out, expansion and maintenance of the statistical model will be a very huge task, and the huge workload makes it difficult to guarantee the accuracy of the model
