Abstract

The invention discloses a marginal unit positioning method and a marginal unit positioning system based on dual simplex sensitivity analysis. Based on a dual simplex algorithm and a sensitivity analysis principle, marginal unit positioning is realized; the invention is suitable for various conditions such as limited and out-of-limit blocked section branch equipment; the invention has the characteristics of universality, small calculation amount and high accuracy; the limitation of traditional marginal unit positioning is broken through, and a powerful analysis means is provided for electric power spot market price analysis.

Description

technical field [0001] The invention belongs to the technical field of electric power dispatching automation, and in particular relates to a positioning method and a positioning system for marginal units based on dual simplex sensitivity analysis. Background technique [0002] At present, the first batch of eight pilot units in China have completed the long-term uninterrupted settlement trial operation, further testing the integrity and adaptability of market rules and technical support systems, and some of the first pilot units have shifted from bidding and clearing on the power generation side In order to clear the issue through centralized bidding on both sides of the issuer, the awareness of the main body of the issuer’s bilateral market has been cultivated, and valuable experience has been accumulated for the official operation of the spot market in the later stage. [0003] Due to the differences in the grid structure and power supply technical characteristics of the f...
