Contribution to Conference
This paper proposes a control scheme to coordinate the DC voltage of converters in a HVDC grid using a Multi-agent System concept. Such interactions between agents, converters, and communication units are approached from a Cyber-Physical System (CPS) perspective. The Multi-agent based control scheme tries to update the DC voltage set-points of the converters based on local and neighboring information. The information exchange between the agents and communication delay tolerance of the control scheme is studied by means of graph theory. The multi-agent control scheme has been implemented for a seven-terminal HVDC grid in a real time simulator and the impact of communication delay on this distributed control approach has been studied and is presented in the result.
