Abstract [en]

The main objective of this master thesis is to design, implement and test a systematic

methodology for integration of Network Manager, an electric power system

control center package from ABB Ventyx, and Aristo, a real-time power system simulator

from Svenska Kraftnätt. Such a setup is useful for Demand Response studies

in Active Distribution Networks. A case study has been performed to demonstrate

the usefulness of the implemented setup in such a scenario.

The integration between the two programs is done via CIM for topology exchange

from Aristo to Network Manager and via a combination of OPC UA and OPC DA

for bidirectional real-time data exchange. By making the required adjustments, the

programs are successfully interfaced. The integration encompassed changes to the

Aristo CIM Exporter and Network Manager CIM Importer, specifically the XSLTs

and import definitions. Also changes to Network Manager’s OPC UA Client are

made.

In parallel a local controller is developed that can perform local control actions on

the simulated power system as well. It performs a Transformer Mode Switching

Optimization function with the help of OPC UA. The program itself is written in

JACK with the help of a pre-fabricated Java OPC UA stack and client from Prosys

OPC.

Finally the three programs (Network Manager, Aristo and the local controller) are

used together to simulate a test scenario. In this test scenario, manual changes

are made to the simulated power grid via Network Manager, as well as automatic

changes via the local controller. In order to perform this scenario, all programs

have to cooperate. The test scenario shows that every aspect of the integration is

a success.

Industrial significance of this master thesis is the provision of a useful integration

that can actually be used to improve the operations. It is likely that ABB will use

the the integration for operator training, enabling operator proactive control and

analysis of grid investment effects.
