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...

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. Determine the evaluation index, according to the influence of the parameter on the sensitivity of the evaluation index, use the sensitivity change as the feedback result to feed back the impact of the parameter on the market clearing, and optimize the impact to make the clearing result stable and ensure the safe and stable operation of the electricity market
