Abstract

There have been several problems in information exchange between actors in the disturbances of electricity supply. For example in storm 2011 in Finland, a municipality had problem to contact their local distribution system operator (DSO) because they had only the phone number of DSO’s customer service, which was congested.

At present, the situation awareness in disturbances of electricity supply is focused on every actors own perspective. In addition, present sources of SA are shattered.

In this research, the demonstration of inter-organizational situation awareness system to disturbances of electricity supply is developed.
T
he design process has been iterative. The usability of the first version of the demonstration has been evaluated with Nielsen’s heuristic evaluation method. The needs of information exchange have been studied by user need interviews with one municipality and two fire and rescue service.

The theory of team SA is inadequate in case of disturbances of electricity supply. Different actors do not have common sub-goals. There is a need for extension of the team SA theory to cover cases where sub-goals are more likely linked to each other than common.

The designed demonstration improves information exchange between actors. In addition, it improves the resilience of society in disturbances by helping the authorities to focus their actions to sites that do not have electricity and or mobile network.

The main difference that the demonstration has to existing methods is that there is a criticality database where information about sites that are highly dependent on electricity is stored. In addition, the demonstration combines information from multiple different actors to same view.

In this research it was clarified that inter-organizational situation awareness system can change the thinking about how the restoration process of electricity distribution network in disturbances should be formed.
