Modern Active Distribution Networks (ADN) are of distributed nature in their operation and control. Multi-agent systems (MAS) have several inherent characteristics which motivate a significant interest in their application in control and automation of ADN. Interoperability is an important consideration for both communication between agents as well as for agent to power system equipment. This paper proposes an IEC61850 interface based multiagent system architecture for distribution network operation and control. A case study is also performed to prove the proposed concept.
