Day-ahead plan safety checking method based on research states

Abstract

The invention discloses a day-ahead plan safety checking method based on research states. The method comprises steps of according to research requirements, selecting power grid day-ahead operation real-time mode data or stored history mode data to serve as the basic power grid operation mode for the day-ahead plan safety checking; loading the selected basic mode into an application owned by a user and displaying basic state tide information on a factory station map; carrying out operation mode adjustment, and modifying investment and stopping states or measurement values of a circuit breaker, a disconnecting link, a bus, a circuit, a transformer and a generator; and carrying out basic state safety analysis on the basic state tide mode with the adjusted mode, and estimating device overload, cross section threshold crossing and bus voltage thread crossing conditions. In this way, tide and voltage thread crossing conditions are adjusted and eliminated further, so the basic tide cross section required by the research is obtained. A practical and effective method is provided for adjustment and safety checking of the day-ahead plan mode of the electric power system.

Description

technical field [0001] The present invention belongs to the technical field of electric power system and automation thereof. More precisely, the present invention relates to a safety verification method of a day-ahead plan based on a research state, which is based on a research state mode and comprehensively applies a graphical basic method and plan data adjustment. Integrating planning data for tie-line power adjustments with power generation and load sensitivity in mind, multi-section, multi-stage parallel calculations and various technical means, methods for adjusting and safety-checking day-ahead planning data. Background technique [0002] With the advancement of electricity market reform, the functions of the electricity trading platform have been gradually improved to provide support for market development. Based on annual bilateral negotiations and monthly centralized competition power contracts, the types of transactions will be further enriched, and the day-ahead t...

Problems solved by technology

[0004] The deficiencies in the existing day-ahead plan security check analysis and calculation include: 1) Adopting the automatic operation mode, it is impossible to manually participate in the selection of basic method data, and it is also impossible to adjust the basic method and plan data; There is a large difference in the modeling range of mode data, and there is a large error between the tie line flow and the tie line plan in the generated planning mode data; 3) It is necessary to perform an overall check on the 96-point mode data of the day-ahead plan each time, and cannot be individually checked and specified time plan data
