Embodiment Construction

[0058] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0059] For convenience the present invention is understood, at first introduce relevant technical terms:

[0060] (1) Power dispatching:

[0061] Power dispatching is an effective management method adopted to ensure the safe and stable operation of the power grid, reliable external power supply, and orderly progress of various power production tasks. The specific work content of power dispatching is based on the data information fed back by various information collection equipment, or the information provided by monitoring personnel, combined with the actual operating p...

Abstract

The invention provides an active scheduling model and scheduling system with least wind curtailment wherein the scheduling system comprises a power generation set role assignment module, a rolling scheduling module, a real-time scheduling module and an AGC control module. The active scheduling model with the least wind curtailment is applied to the real-time scheduling module. According to the real-time wind power forecast result, the power generation requirement can be corrected in real time so as to correct the effort plan of all power generation sets in the remaining period, to enable that the overall effort of the power generation sets to be gradually close to the actual power generation requirement, to reduce the uncertainty faced by the current plan and to ensure that the effort plan of the power generation sets are more proper and of more significance.

Description

technical field [0001] The invention belongs to the technical field of electric power dispatching, and in particular relates to an active power dispatching model and a dispatching system with minimum wind curtailment. Background technique [0002] Power system economic dispatch refers to a dispatch method that realizes the reasonable distribution of generation load among units at the most economical operating cost and ensures reliable power supply to users under the conditions of network security and generation load balance. According to different optimization periods, the power system optimal dispatching problem can be divided into two aspects: static optimal dispatching and dynamic optimal dispatching. [0003] Static optimal dispatch refers to the problem of optimal distribution of economic load for a single operating time section of the power system. Static optimal dispatch is mainly divided into two categories in terms of algorithm: classical economic dispatch based on...
