Features:• To assist decision making• Integrating information from different sources• Integrating different application (Disturbance Draw)• Displaying information in suitable for the Operator:

• user profile• positioning context• device context

Requirements for the underlying software products:• Open application programming interfaces (APIs) to integrate other applications• Web aware to enable WebServices • Location information of objects (feeders, substations etc.) should be accessible via some standard format

Summary, Conclusions and Future work

Summary:

• GUN platform was used as a future test bed for electricity distribution system

• Possible scenerios for importing and exporting information between different domains were recognized

• Utilizing the learning capabilities of agents, e.g. faults of the power network and their solutions can be shared between the agents

Conclusions:

• Interoperability, automation and integration features of GUN platform were utilized

• Context information supports expert (Operator) in decision making process

• Dashboard hides the underlying applications and WebServices that provide the online information

Future work: • More complicated features of agents and their collaboration in Multiagent system (MAS)
