Coordinated optimization method for enabling bilateral power contracts to participate in day-ahead electric power and energy balance

Abstract

The invention discloses a coordinated optimization method for enabling bilateral power contracts to participate in day-ahead electric power and energy balance. The method comprises steps: the opening-equity-justice contract energy of each power plant in a future day is acquired, the bilateral power contract data or unit bilateral power contract data of the power plant are acquired, and the contract reduction factor of each power plant is determined; predicted data of system load for the future 24 hours and the basic parameters of each thermal unit and the coal consumption characteristics are acquired; according to a bilateral power contract type, an optimization model is built, a target function is determined, constraint conditions are set, and a mixed integer programming problem is solved; and the startup-shutdown plan of the unit in the future 24 hours, the output plan of the unit and the power plant reduction amount are finally determined. In the technical scheme of the invention, the unit output is decomposed to a bilateral output part, an opening-equity-justice output part and other output parts, reasonable constraints are built to enable the actual bilateral output to be no larger than the output specified by a corresponding contract, the contract adjustment amount in the target function is ensured not to be negative, and the solving difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power market, in particular to a method for coordinating and optimizing the balance of electric power before the participation of bilateral electric power contracts. Background technique [0002] The electricity in the international typical electricity market is all market electricity, and there are still many regions and countries where market electricity and planned electricity coexist; Bilateral contracts are physical power contracts with execution constraints, and the day-ahead planning and arrangement need to consider the execution of bilateral transactions; unlike the balance mechanism in developed countries, the market maturity of the main market players in many regions and national electricity markets is not high at the initial stage, and there is no capacity for increase or decrease. Bilateral transaction adjustments cannot be made based on the increase or decrease of quotations. [000...
