The invention discloses a key-section-based method for unit partition identification and effective spare allocation, and relates to the technical field of power system operation and control. The availability of power system backup has a major impact on operational safety. The invention includes the steps of: establishing a section-based standby partition model of the power system, determining the power transmission distribution factor between each generating set and the key section of the power grid, and dividing the generator set according to the positive and negative relationship between different generating sets and the power transmission distribution factor. The reserve partition of the power system; the reserve capacity joint optimization dispatching model is solved, and the key section limit constraints are included and solved, and the output of the generator and the standby arrangement are obtained. This technical solution comprehensively considers the influence of the generator set on the power flow of the key section, avoids the occurrence of actual unavailability caused by factors such as overload of the operating section during the call of the spare auxiliary service bid capacity provided by the generator set, and improves the operation safety of the power system.
Description
technical field [0001] The invention relates to the technical field of power system operation and control, in particular to a key section-based unit partition identification and an effective backup allocation method. Background technique [0002] At present, with the comprehensive development of the power market reform, how to discover the effectiveness of the power system backup has become an important challenge that affects the efficiency of the power market and the safety of the power system. At the same time, the standby auxiliary service bid capacity provided by the generator set cannot be actually unavailable due to factors such as overloading of the operating section, which brings challenges to the safe operation of the power system. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide a key section-based unit partitio...
