Embodiment Construction
[0101] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0102] Such as figure 1 Shown, the present invention comprises steps:
[0103] 1) Establish a section-based power system backup partition model, determine the power transmission distribution factor between each generating set and the key section of the power grid, and divide the power system to which the generating set belongs according to the positive and negative relationship between different generating sets and the power transmission distribution factor spare partition;
[0104] 2) Establish a joint optimal dispatching model of reserve capacity based on power transmission distribution factors, incorporate constraints into the joint optimal dispatching model of reserve capacity, and solve based on the critical section limit caused by the reserve partition of the power system; the constraints include: based on the reserve partitio...

The invention discloses a unit partition recognition and effective standby distribution method based on a key section, and relates to the technical field of power system operation and control. The standby effectiveness of the power system has a great influence on the operation safety. The method comprises the following steps: establishing a power system standby partition model based on a section,determining a power transmission distribution factor between each generator set and a key section of a power grid, and dividing a power system standby partition to which the generator set belongs according to the positive and negative relationship of different generator sets to the power transmission distribution factor; and the reserve capacity joint optimization scheduling model is solved, key section limit constraints are brought into consideration and solved, and the output and reserve arrangement conditions of the generator are obtained. According to the technical scheme, the influence ofthe generator set on the power flow of the key section is comprehensively considered, the actual unavailable condition caused by factors such as overload of the operation section in the standard capacity calling process in the standby auxiliary service provided by the generator set is avoided, and the operation safety of the power system is improved.
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...
