Electric power spot market clearing method, system, device and readable storage medium

Abstract

The invention belongs to the field of power markets, and discloses a power spot day-ahead market clearing method, a system, a device, and a readable storage medium, and the method comprises the steps:obtaining the declaration information and operation boundary conditions of a power grid; determining the maximum declared power generation capacity of the power grid according to the operation stateof each device in the power grid in the next day, and verifying the declared information of the power grid according to the maximum declared power generation capacity; performing day-ahead market ground state clearing according to the application information passing the verification and the operation boundary condition of the power grid, correcting a future state network model according to a ground state clearing result, obtaining a future state section limit of the power grid according to the ground state clearing result, and correcting the operation boundary condition of the power grid according to the future state section limit; and performing day-ahead market clearing according to the declaration information passing the verification and the corrected operation boundary conditions. Thedeclaration information is verified through the maximum declaration power generation capacity, the operation boundary condition is corrected through the future-state section limit, the accurate clearing 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 method, system, equipment and readable storage medium for clearing electric power spot day-ahead market. Background technique [0002] The day-ahead power spot market clearing is based on the declaration information of market members and the boundary conditions of the power grid operation, using safety-constrained equipment combinations and safety-constrained economic scheduling procedures for optimized calculations, and clearing results in day-ahead spot market transactions. Therefore, the validity of market member declarations and the accuracy of grid operation boundary conditions are the keys to the rationality and accuracy of day-ahead market clearing results. [0003] However, the current clearing process of the spot power day-ahead market is often based on declaration data that only conforms to the simple verification of the declaration rules and an insufficiently refin...
