Embodiment 1

[0064] In the actual operation of the spot operation system, due to input data errors, malicious quotations, program operation failures, network failures, system failures and other reasons, the optimized clearing has no solution or abnormal solution. As a result, the day-ahead plan cannot be issued, the day-ahead market electricity price cannot be released, and the revenue and expenses of market members cannot be settled normally, seriously endangering the security of the power grid and the interests of market members. Therefore, if figure 1 As shown, the present invention provides a method for dealing with the abnormality of the optimized clearing result of the day-ahead electric energy market, including:

[0065] Step S1, based on the pre-set verification conditions, verify the rationality of the input data participating in the optimized clearing, and correct the abnormal data when there is abnormal data;

[0066] Step S2, bringing the input data that has passed the rationa...

Embodiment 2

[0087] In this embodiment, the provincial spot market is taken as an example to test a method for dealing with the abnormality of the day-ahead market optimization clearing results provided by the present invention, so as to ensure that the accuracy of the day-ahead node marginal electricity price and the day-ahead market clearing power is reasonably acceptable. , to ensure the stable operation of the day-ahead market, thereby safeguarding the security of the power grid and the interests of market members. The processing procedure is as follows: figure 2 shown, including:

[0088] Step 1: Before optimizing and clearing, perform a data rationality check on the input data for optimization and clearing to avoid unsolvable optimization problems caused by input data errors. The objects of verification include data declared by market members, system operation data, state estimation data, measurement and collection data, output data of multi-day unit combinations, fixed start-stop u...

Embodiment 3

[0118] Based on the same inventive concept, the present invention also provides a processing system for abnormal clearing results of day-ahead market optimization, including:

[0119] The rationality verification module is used to verify the rationality of the input data participating in the optimized clearing based on the pre-set verification conditions, and correct the abnormal data when there is abnormal data;

[0120] The optimization calculation module is used to bring the input data that has passed the rationality check into the pre-built optimized clearance model for calculation;

[0121] The exception handling module is used to adjust and calculate the optimized clearing model by executing the fault tolerance strategy step by step based on the preset fault tolerance mode until the clearing result is obtained;

[0122] Wherein, the preset fault-tolerant mode includes a multi-level fault-tolerant strategy, and the multi-level fault-tolerant strategy includes: reducing co...

Abstract

The invention provides a processing method and system for daily market optimization clearing result abnormities and the method comprises the steps: carrying out rationality verification of input dataparticipating in optimization clearing based on a preset verification condition, and correcting the abnormal data when there is abnormal data; substituting the input data passing the rationality verification into a pre-constructed optimized clearing model for calculation; based on a preset fault-tolerant mode, executing a fault-tolerant strategy step by step to adjust and calculate the optimized clearing model until a clearing result is obtained; wherein the preset fault-tolerant mode comprises a multi-stage fault-tolerant strategy, and the multi-stage fault-tolerant strategy comprises reduction of convergence precision, unconstrained clearing and revision of node marginal electricity price. According to the technical scheme provided by the invention, the accuracy of the daily node marginal electricity price and the accuracy of the daily market clearing power are ensured to reach the reasonably accepted degree, the steady operation of the daily market is ensured, and the power grid safety and the interests of market members are further ensured.

Description

technical field [0001] The invention relates to the field of electric power automation, and in particular to a method and system for processing abnormal results of day-ahead market optimization and clearing. Background technique [0002] The current electric energy market is an important part of the electric power spot market, and its operation process will directly affect the safety and economy of the power grid operation. The day-ahead electric energy market can form an optimized trading plan that is compatible with the physical operation of the power system and reflects the wishes of market members at a certain time in advance, and promotes full competition in electricity trading by means of declaration and clearing, and realizes the efficiency and optimization of power resources Configuration; play the function of market price formation, can truly reflect the short-term supply and demand relationship and space-time value of power commodities, and provide real price signa...
