Problems solved by technology

The original dual interior point method has the advantages of fast calculation speed and does not slow down with the increase of network scale, but the discrete variable processing is not strong; while the tabu search calculation method has the advantages of strong discrete variable processing ability, it is different from other artificial intelligence methods. Compared with the computational efficiency, it is relatively fast, but compared with the traditional mathematical method, the computational efficiency is still low
In terms of solving th

Embodiment Construction

[0111] Below is an embodiment of the inventive method, carries out the emulation experiment with the real-time data section of a certain day in Chongqing power grid in 2008 as embodiment, further explanation is as follows:

[0112] The real-time data section has a total of 305 buses, 132 lines, 91 transformers, and an active power loss of 74.5MW. For the convenience of comparison and description, the present invention divides the comprehensive method in the invention into three processes, as shown in Table 1-3, process 1 represents steps 1-2-3-4-5-6 in the calculation process, and process 2 Indicates steps 1-2-3-4-5-6-7 in the calculation process, and process 3 indicates steps 1-2-3-4-7 in the calculation process. If one or more processes are successfully calculated, it means the synthesis If the calculation method is successful, if two or more processes are successfully calculated, the comprehensive calculation method will select the process with the shorter calculation time ...

Abstract

The invention provides a powerless optimizing method based on a primal-dual interior-point method and a taboo search method. The method combines the primal-dual interior-point method and the taboo search method together and can quickly and conveniently process the powerless optimizing calculation of a large scale electric network with a discrete variable by utilizing the characteristics of good astringency of the primal-dual interior-point method as well as the characteristic of convenient processing on the discrete variable of the taboo search method. The optimizing method is also suitable for an automatic voltage control system.

Description

technical field [0001] The invention relates to the field of power system calculation, in particular to a reactive power optimization method suitable for on-line application. Background technique [0002] Power quality is an important indicator of power supply quality. Guaranteeing the voltage quality is also on the agenda. At present, the voltage control mainly depends on the reactive power adjustment of the power supply company. Insufficient reactive power will lead to a decrease in system voltage, insufficient utilization of electrical equipment, and even a series of accidents such as voltage collapse; and Excessive reactive power will also deteriorate the system voltage, endangering the safety of the system and equipment, and too much reactive power backup will waste unnecessary investment. In short, it is very necessary for power supply enterprises to reduce network loss and ensure voltage quality through online reactive power optimization. [0003] Reactive power opt...
