Highlights

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
