Abstract

The invention belongs to the field of electricity market dealings and designs a cross-province electricity generation contract assignment matchmaking dealing voidance method. The method roughly comprises the processes that (1) basic data relevant to a transferor and a transferee is acquired; (2) a price difference matrix of the transferor and the transferee is formed; (3) a maximum value in the current matrix is selected, a corresponding minimum value of a remaining electric quantity of the transferor and the transferee is taken to serve as a pre-dealing electric quantity, and if the minimum value is smaller than or equal to zero, the dealing is ended, and the step (7) is turned to; (4) if the dealing electric quantity of a factory cluster, where the transferee (transferor) is located, plus the pre-dealing electric quantity exceeds a constraint electric quantity upper limit, the pre-dealing electric quantity is changed to be an electric quantity obtained by subtracting the dealing electric quantity of the factory cluster from the constraint electric quantity upper limit; (5) the dealing result is recorded, and the dealing electric quantity is subtracted from the remaining electricquantity of the transferor and the transferee; (6) if the remaining electric quantity of the transferor and the transferee is zero, all elements in a corresponding column or row in a social welfare matrix are set to be zero, and the step (3) is turned to; and (7) matchmaking is ended, and a dealing price is calculated.

Description

technical field [0001] The invention belongs to the technical field of electric power market transactions, and in particular relates to a method for clearing transactions of cross-provincial power generation contract transfer and matching transactions. Background technique [0002] The power generation right contract transfer transaction is a transaction form in which power plants realize the transfer of power generation shares through bidding. With the deepening of my country's power market reform, each province has launched a market for annual bilateral negotiations and monthly centralized competition. The two parties to the transaction are based on the annual or quarterly power generation plan indicators determined by the power authority, under the principle of equality and voluntariness, without affecting power consumption. Under the premise of the interests of the parties and the security of the system, the purchase and sale of large-scale electricity indicators will be ...
