Abstract

The invention belongs to the field of power markets, and more particularly, relates to a monthly centralized matchmaking tradeoff clearing method in consideration of power plant group trading electricity constraints. According to the electricity, the prices and the comprehensive order declared by a power generation enterprise and a power user, a social welfare matrix for a declared price difference between the power generation enterprise and the power user is formed. firstly, power plants in the power plant group are sorted according to quotations from low to high, the power plant quotation meeting the minimum electricity is set to be the lowest limited price, and clearing out is ensured; through traversing the largest elements greater than zero in the social welfare matrix, a matching trading relationship between a power generation enterprise and a power user is formed sequentially, and the pre-traded electricity is acquired; and whether the pre-traded electricity exceeds the maximumtrading electricity limit of the power plant group of the power generation enterprise is further judged, corresponding reduction is carried out in the case of exceeding, the traded electricity is thusin a given limit range, and the trading result is ensured to meet power grid safe operation requirements. The method is high in calculation efficiency and little in implementation difficulty, safetyconstraints can be ensured to be met, and a strong engineering practical value is realized.

Description

technical field [0001] The invention belongs to the field of electric power market, and more specifically relates to a monthly centralized matching transaction clearing method considering the constraint of power plant group transaction quantity. Background technique [0002] Electric matching transactions are also known as "high-low matching", that is, buyers are prioritized according to the quotation from high to low, and sellers are prioritized according to the quotation from low to high. Under certain network constraints, the transactions of buyers and sellers with the highest priority are matched first, and then the transactions of market members with the second highest priority are matched, and so on. [0003] Centralized matching transaction is a form of transaction between power plants and users to realize electricity consumption and sales through bidding. With the deepening of the reform of my country's electricity market, various places have launched annual bilater...
