Achievements
Control architecture
The control centre (master agent) placed in the primary
substation Groß Reken gains measurements from all slave
agents. Also it is able to send switching commands to
switching agents.
The master agent features different functionalities which
enable supervision, control and decision making:
• Control and decision module
• Forecast module
• Execution module
• Topology optimization module
• Post-fault operation module (FDIR)
• Data storage/SCADA Interface
Slave agents are responsible for
• Measurements
• Switching
• Local state evaluation
• Local forecasting
Demonstration of advanced
MV-network operation
using multi agent system
Most of the functionalities are already implemented and
being tested
The working communication
chain is established:
- network model
- slave agent
- master agent
Agents are implemented on
automation devices – RTU560
(remote terminal unit)
Ongoing laboratory implementation and testing of the system
• Hardware-in-the-loop simulation with real automation
devices from ABB
• Quasi real time network representation on a PC system

State Machine Principle
Depending on the measurements and defined voltage/current
limits different system states are defined:
For every operative state action schemes are developed
