Problems solved by technology

[0003] The existing mid-to-long-term electricity decomposition model needs to use a quadratic programming solver, which makes it difficult to solve the model when the solution model is large; at the same time, if it is necessary to roll the unfinished contract electricity (that is, the deviation electricity) to the subs

Abstract

The invention discloses an electric quantity rolling decomposition engineering method. Medium-and-long-term contract electric quantity decomposition is one of the main work of electric power trading centers of all power grid companies, and when the electric power trading centers of all power grid companies make annual power generation plans at the beginning of the year, annual contract electric quantity needs to be decomposed into months in the year according to monthly load prediction, unit startup capacity and other factors of the year. Meanwhile, the monthly power generation plan of each month also needs to be decomposed from the day-ahead period to the intra-day period. In addition, in the actual execution of the power generation plan, the decomposition scheme needs to be subjected torolling correction according to the completion condition of the power generation plan in each previous time period. The high-quality contract electric quantity decomposition scheme can greatly reducethe difficulty of subsequent daily scheduling, and is a basis for economic scheduling and energy-saving power generation scheduling of a power grid, thereby having very important significance.

Description

technical field [0001] The invention relates to a power rolling decomposition engineering algorithm considering the average load rate of units in the whole network and the degree of contract completion, and belongs to the field of power system automation. Background technique [0002] The power distribution of medium and long-term contracts is one of the main tasks of power trading centers of power grid companies. When power trading centers of power grid companies formulate annual power generation plans at the beginning of the year, they need to calculate annual The contract electricity is evenly decomposed into each month of the year. At the same time, the monthly power generation plan of each month also needs to be decomposed from the day to the time period. In addition, in the actual implementation of the power generation plan, it is also necessary to make rolling corrections to the decomposition scheme according to the completion of the power generation plan in previous...
