Section interaction day-ahead market clearing method, system, device and storage medium

Abstract

The invention belongs to the field of power markets, and discloses a section interaction day-ahead market clearing method, system and device, and a storage medium, and the method comprises the steps:obtaining a network topology model, declaration information and an operation boundary condition of a power grid; based on the network topology model, performing clearing calculation according to the declaration information and the operation boundary conditions to obtain a ground state clearing result; determining a future-state operation mode of the power grid according to the ground-state clearing result to obtain a future-state network topology model of the power grid; based on the future-state network topology model, obtaining a future-state section limit of the power grid according to a ground-state clearing result, and correcting an operation boundary condition according to the future-state section limit; and based on the future state network topology model, according to the declaration information and the corrected operation boundary conditions, performing day-ahead market clearing by taking power generation cost minimization as an optimization target, and obtaining a clearing result. The operation boundary condition is corrected through the future-state section limit, the accurate operation boundary condition is provided, and the accuracy and rationality of the clearing result are improved.

Description

technical field [0001] The invention belongs to the field of electric power market, and relates to a cross-section interactive day-ahead market clearing method, system, equipment and storage medium. Background technique [0002] In the field of electricity market, the clearing of the power spot day-ahead market is based on the declaration information of market members and the boundary conditions of the power grid operation, using the safety-constrained unit combination and the safety-constrained economic scheduling program to optimize the calculation, and the market transaction results are obtained from the clearing. With the power market With the rapid advancement of globalization reforms and the continuous expansion of the scale of market trading electricity, higher requirements have been put forward for the rationality of the results of spot clearing of electricity. [0003] However, at present, when determining the grid operation boundary conditions used in the calculati...
