A Study of Autonomous Decentralized Voltage Profile Control of Distribution Network considering Cooperation with Voltage Control Equipments

摘要

This paper first presents voltage profile control method using power factor control of distributed generations(DGs) based in autonomous decentralized voltage control method using multi-agent technology, feedback control. This method can maintain voltage quickly and saving reactive power of DGs excessively. Second, a combined voltage control of Static Voltage Regulator (SVR) SC, and DGs, which is also based autonomous decentralized control, is proposed. DGs play a role in maintaining voltage quickly as possible when voltage changed intensely, and tap control of SVR and SC play a role in compensating the injected reactive power of DG in order to save controlled reactive power of DGs by V-Reference methods of DGs. Besides, when two or more feeders in which a number of DGs is connected are behind SVR, the hunting problem is investigated because V-Reference method and Q-Cooperation method of DGs function contradictorily.
