Composite power grid operation risk scene construction method, system, equipment and medium

Abstract

The invention discloses a composite power grid operation risk scene construction method, system and device and a medium, and the method comprises the following steps: carrying out the clustering based on the output sample data, obtained through sampling, of a composite power grid with the new energy permeability as a clustering object, and obtaining a typical wind power scene, clustering by taking the load data as a clustering object to obtain a typical load scene; performing pairing based on the typical wind power scene and the typical load scene, and constructing and obtaining a system operation scene; wherein the system operation scene is a source load matching scene in which a typical wind power scene and a typical load scene are combined in pairs; and combining the system operation scene with a predetermined system risk index to construct and obtain a composite power grid operation risk scene. According to the invention, a composite power grid operation risk scene can be obtained, and a verification environment can be provided for reasonable distribution of traditional unit output and new energy unit output.

Problems solved by technology

However, due to the intermittence, volatility, and randomness of new energy output such as wind power, coupled with the randomness of the existing load power in the power system, it will lead to complex and diverse operating conditions of the power system, and will also lead to risks in the operation of the power system. The significant increase has brought new challenges to the safe and stable operation of the power system, making the risk assessment of power grid operation more difficult and the workload is huge

[0003] At present, the existing technologies often focus on risk assessment or scenario clustering, and there are few descriptions on the construction methods of high-risk operation scenarios in which a high proportion of new energy is connected to the grid; in addition, the existing technologies are not perfect in scenario clustering. The proportion of energy access to the power grid is increasing, but the existing technology does not reflect the characteristics of high penetration of new energy in the high-proportion new energy power system, and cannot provide an optimal power dispatching scheme for uncertainty under the high-proportion new energy power system
