30-second cycle static analysis based electric power spot transaction security checking method

Abstract

The invention relates to a 30-second cycle static analysis based electric power spot transaction security checking method, which comprises the steps that firstly an electric power regulation and control center receives spot transaction data sent by an electric power transaction department and performs online security analysis data preparation, then the regulation and control center performs static security analysis, and finally the regulation and control center provides a transaction center online stability control check result and an auxiliary service strategy. The method provided by the invention not only can improve the online security analysis capacity of a power grid, also can effectively deal with rapid changes of electric power spot transactions, thereby providing safe and stable running guarantee for development of the electric power market in China, and realizing coordination and unification of safe running of the power grid and orderly operation of the market.

Description

technical field [0001] The invention belongs to the field of smart grid dispatching, and mainly relates to a method for checking the safety of electric power spot transactions based on a 30-second period static analysis. Background technique [0002] During the "Twelfth Five-Year Plan" period, the State Grid has basically completed the "three vertical and three horizontal" UHV grids as the backbone grid. Hybrid grid. With the advancement of UHV power grid construction, the application of a large number of power electronic components such as direct current transmission and FACTS, and the large-scale access of wind power and photovoltaic new energy sources, the operating pressure is increasing, the safety and stability levels are mutually restricted, and resources are optimized. Contradictions with safety issues are prominent. The traditional method of power grid operation arrangement is increasingly difficult to adapt to the needs of future UHV large power grid operation, t...

AI Technical Summary

Problems solved by technology

The traditional method of power grid operation arrangement is increasingly difficult to adapt to the needs of future UHV large power grid operation, difficult to adapt to increasingly complex and changeable operation regulations, and difficult to adapt to the sharp increase in the workload of power grid operation arrangements

During the "13th Five-Year Plan" period, cross-regional spot trading of electricity will be fully launched. In order to alleviate problems such as abandoning water, wind, and light, the State Grid has formulated the rules for the spot market of surplus renewable energy across provinces and regions. Cross-regional transactions directly lead to sudden changes in the power-on mode, power flow, and static and transient stability of the power grid at the receiving end
