Embodiment Construction

[0054] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0055] The rotating reserve optimization method under multiple scenarios of the present invention uses the scenario aggregation and screening method considering the remaining risk of the entire scenario set as a strategy, firstly combines the reserve measures (reserve measure, RM) selected in the optimization of the previous iteration step, and calculates the entire scenario set The sum of the residual risks of the following scenarios. If the sum of the residual risks under the full scenario set is less than the set total residual risk threshold, the rotation RM optimization selection under the scenario set ends; otherwise, set the subset of scenarios whose residual risk under the full scenario set exceeds the residual risk threshold of a s...

Abstract

The invention discloses a rotational reserve optimization method employing risk stepwise polymerization scene. The rotational reserve optimization method comprises the steps of firstly, optimizing selected reserve measure combination of a previous iterative step, calculating sum of remaining risks of each scene under all scene sets, ending rotational reserve measure (reserve measure RM) optimization selection under the scene sets if the sum of the remaining risks under all scene sets is smaller than the set total remaining risk threshold, otherwise, setting scene sub-sets with remaining risk exceeding a single scene remaining risk threshold under all scene sets to be a scene set to be polymerized; clustering a single scene according to scene probability distance, adding the single scene toa scene set to be optimized, and allocating the scene probability in the scene set to be optimized again; and finally, optimizing RM selection by many steps according to cost performance ratio. The rotational reserve optimization method is high in calculation effect and good in optimization effect, and the calculation efficiency and the total control risk can be coordinated very well.

Description

technical field [0001] The invention relates to a spinning reserve optimization method using risk gradual aggregation scenarios, and belongs to the technical field of power system unit combination. Background technique [0002] The output uncertainty of large-scale intermittent renewable energy (renewable energy, RE) access brings great challenges to the adequacy of system operation. In order to cope with this output uncertainty, it is usually necessary to optimize the purchase of reserve capacity resources in the market to meet the system operation requirements. [0003] In the prior art, the processing methods for the uncertainty of RE output can be mainly divided into three categories. One is to describe the RE through the deterministic output curve obtained by point prediction, and then add a spinning reserve capacity with a fixed ratio of RE output to stabilize its uncertainty. Certainty; or use the confidence interval to describe the uncertainty of RE output, and dete...
