doi:10.3969/j.issn.1000-7229.2015.05.012

Abstract

Abstract:

For the coordinate control of interconnecting transformer and reactive power compensation device in active distributed network, this paper proposed a global coordinated control model based on multi-agent technology. Multi-agent technology with its flexible structure and agent autonomy could combine the centralized control with the distributed control better； and realize the dynamic tracking of weak-voltage node in voltage over-limit area through building the regional leading agent decision model. By combining CNP （contract net protocol） and voltage regulation priority principle, it could achieve the timing optimization for the compensation amount calculation of interconnecting transformer and regional reactive power compensation elements, through the competition of reactive power-voltage sensitivity index. Finally, this paper carried on the simulation in IEEE33 distribution system, whose results showed that the multi-agent technology could realize the voltage regulation by combine interconnecting transformer with reactive power compensation device.

Key words: multi-agent technology, active distribution network, on-load tap changer （OLTC）, reactive power compensation device, coordinated control
