Quantitative optimization analysis method and system for uncertain factors of comprehensive service station

Abstract

The invention provides a quantitative optimization analysis method and system for uncertain factors of a comprehensive service station. The method comprises the following steps: constructing a probability distribution model of various uncertain factors of the comprehensive service station; introducing stochastic programming and scene analysis, converting comprehensive service station optimization scheduling containing the uncertain factors into optimization of a plurality of determined scenes, wherein each scene set is the probability of the running state of the comprehensive service station at the current time; and calculating expected loss by using a conditional value-at-risk theory, and measuring the influence of uncertain factor fluctuation on a decision target. According to the method, the probability distribution model of various uncertain factors of the comprehensive service station is constructed, the random programming theory and the conditional value-at-risk theory are applied, the influence of uncertain factor fluctuation on a decision-making target is measured, and a bidding model of the comprehensive service station for optimizing multi-type resource output in a market environment is established; the model gives consideration to the robustness and economy of the bidding decision of the comprehensive service station, can deal with severe scenes, and is more practical.

Description

technical field [0001] The invention relates to the technical field of energy internet, in particular to a quantitative optimization analysis method and system for uncertain factors of comprehensive service stations. Background technique [0002] In order to implement the national strategic goal of "carbon peaking and carbon neutrality" and adapt to the new social form, it is necessary to make use of the advantages of traditional substations in good location, wide distribution and good resources, combined with the development of distributed energy and big data, research and exploration based on Substation resources construction and operation of charging and swapping (energy storage) stations and data center stations "multi-station in one" new energy Internet comprehensive service station model. With the substation as the center, it extends to both sides of the supply area, and integrates the source, network, load and storage business according to local conditions, so that th...
