Abstract

The invention provides an electricity market parameter influence index sensitivity analysis method and device, and a storage medium, and belongs to the technical field of electricity markets. The problem that the clearing result is influenced by parameters in the prior art is solved. The method comprises the following steps: S1, building an electricity market simulation system, and building an evaluation index sensitivity model in the simulation system; S2, inputting economic data, electric quantity data and operation data into the evaluation index sensitivity model, collecting parameter information, and using the evaluation index sensitivity model to construct an evaluation curve graph; S3, setting a plurality of parameter change values for each parameter, inputting the plurality of parameter change values into an evaluation index sensitivity model, and drawing a sensitivity curve formed by an economic evaluation index, an electric quantity evaluation index and an operation evaluation index on the evaluation curve graph by the evaluation index sensitivity model according to the parameter change values; and S4, analyzing the sensitivity curve by the power market simulation system, and outputting an optimized result aiming at the sensitivity change of the evaluation index. The method and the device have the advantages of analyzing and optimizing results and the like.

Description

technical field [0001] The invention belongs to the technical field of analysis methods, and in particular relates to a sensitivity analysis method, device and storage medium of an electric power market parameter influence index. Background technique [0002] At this stage, the model used by the power spot market technical support system for clearing is based on the establishment of safety constrained unit combination (SCUC) and safety constrained economic dispatch (SCED) models and optimized calculations. The clearing results of the electricity market are closely related to various parameters, such as model parameters, including power grid parameters, scheduled backup, frequency regulation, and load forecasting; Influenced; in addition to the parameters on the model, the algorithm-related parameters set in SCUC and SCED will also affect the clearing results. [0003] Various parameters in the market clearing will directly affect the market clearing results, affect the fair...

AI Technical Summary

Problems solved by technology

In the prior art, there is no method for specific analysis of the influence of parameters on the clearing results, and the existing technology cannot judge whether the parameters will affect the clearing results according to the changing rules of the parameters. Therefore, a method is needed to set the changing rules of the parameters. Determi...
