Embodiment

[0035] The present invention provides a static security verification method for the future operation mode of the power grid considering spot transactions. The planned data is checked and processed, and integrated with the basic operating mode data to generate future time trend data, and then static safety checks are performed.

[0036] Specifically, it includes five steps: acquisition of intraday planning data for spot trading, preparation of grid offline parameter model data, inspection of planning data and basic operation mode data, generation of static safety check method data, and static safety check calculation. The specific description of each step is as follows :

[0037] S1. Intraday planning data acquisition steps for spot transactions: the network / provincial dispatching center receives the spot transaction data sent by the power trading market department of the superior dispatching organization, and extracts the intraday plan data containing spot transaction informat...

Abstract

The invention discloses a power grid future operation mode static security check method considering spot transactions. The method comprises the following steps: S1, acquiring intraday plan data of thespot transactions; S2, acquiring basic operation mode data of the power grid; S3, performing data inspection on the daily plan data and the power grid basic operation mode data, and correcting unreasonable data; S4, on the basis of the daily plan type data and the power grid basic operation mode data, power grid power flow at a future moment is estimated; And S5, assessing whether the power gridis safe or not based on the power grid power flow data at the future moment. According to the invention, data inspection and processing are carried out on the daily plan data in the spot transaction data, the daily plan data are integrated with the basic operation mode data to generate power flow data at a future moment, and then static security check is carried out to realize static security analysis of the future power flow.

Description

technical field [0001] The invention relates to the technical field of smart grid dispatching control, in particular to a static safety check method for a future operation mode of a grid considering spot transactions. Background technique [0002] With the continuous expansion of the operation scale of my country's power grid, especially after the construction of the "three vertical and three horizontal" grid structures of the UHV power grid, and the large-scale intervention of a large number of new energy sources such as wind power and photovoltaics, the operation regulations of the power grid have become increasingly complex, and the workload of power grid operation arrangements has increased significantly. , the traditional power grid operation arrangement has been difficult to meet the needs of future UHV large power grid operation. [0003] In order to solve the current problems of high operating pressure, low resource utilization, and prominent power grid security issue...
