Abstract

The invention discloses an electric power spot market clearing calculation method based on multi-strategy fusion dimension reduction, and the method comprises the steps: firstly obtaining a power gridrange and a calculation period for carrying out the clearing calculation of an electric power spot market, and determining a calculation boundary; then carrying out merging analysis of similar time periods, and reducing the number of time periods for entering clearing calculation; establishing and solving a relaxation safety constraint unit combination model, carrying out invalid start-stop variable identification and effective safety constraint identification according to a calculation result, and reducing the number of start-stop variables and safety constraints entering clearing calculation; establishing a time period merged security constraint unit combination dimension reduction clearing model, and quickly solving to obtain a unit combination result; and carrying out full-time-periodeconomic dispatching and safety check analysis based on a unit combination result, adding the out-of-limit time period and the monitoring section into a unit combination dimension reduction clearingmodel, and finally obtaining an electric power spot market clearing result through iterative computation.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to a calculation method for clearing an electric power spot market based on multi-strategy fusion and dimensionality reduction. Background technique: [0002] The power spot market is an important part of the complete power market system, and it provides a market-oriented means for short-term power supply and demand balance. In the power spot market, power dispatch trading institutions mainly use Security Constrained Unit Commitment (SCUC) and Security Constrained Economic Dispatch (SCED) application software to complete day-ahead and real-time dispatch. [0003] With the rapid development of the modern power system, the scale of the power grid has been further expanded, the number of units considered in power generation dispatching has been increasing, and the limitation of the transmission channel of the power grid operation has beco...
