Reliability and calculating speed are the keys that can it practical.But, the continuous expansion of interconnected electric power system scale and voltage etc.
The continuous lifting of level, after particularly extra-high voltage bulk power grid puts into operation, power network covering region is vast, and interstitial content is numerous, idle work optimization
There is the dimension disasters such as low memory, convergence rate in traditional algorithm and intelligent algorithm, and be difficult to seek it is global most
Excellent solution.Such algorithm is remained in some problems on practical implementation.
Additionally, with the continuous expansion of power network scale and transmission line capability, and New Technologies of Electric Power Transmission a large amount of uses, it is such as big
The use of scale power electronic devices and the development of Survey of Flexible AC Transmission System Technology (FACTS) so that the control shape of unit and system
State is increasingly sophisticated, and many new stability problems are also just following.The several typical electricity occurred in external big interacted system
Pressure collapsibility accident gives us deep warning.Scholars to collapse of voltage sexual behavior thus mechanism do it is further explore and
Research, the constraint of voltage stability is considered from the planning stage, improves reactive-load compensation configuration, it is established that more perfect voltage stability
Appraisement system and preventive measure, are the important means for preventing collapse of voltage risk.
