Small Municipality Blackout: Gniebing microgrid operation use case

In this Use Case we will use the WHY-Toolkit to simulate the behavioural change of the residential consumers in the hamlet of Gniebing in order to obtain a deeper knowledge on the load behaviour of these consumers. The load behaviour will be analysed in a regular supply situation and an emergency supply situation.

The Microgrid use case is based on the real-life implementation of a Microgrid in the Austrian municipality of Gniebing in south-eastern Styria. The Gniebing Microgrid was implemented to support a limited number of consumers during a blackout scenario. For that purpose, two diesel generators and a hydro-plant are being facilitated. At this point no battery storage system is installed and the diesel generators are used for the black-start and act as control reserve of the grid. The use case focuses on renewable energy sources that will replace the diesel generators whenever possible to reduce the amount of diesel consumed. Furthermore, the DSO and the energy supplier, who is a small player in the Austrian electricity supply system, is looking for new business models to approach its customers. As of lately they have observed limited interest in consumers to adopt new business models, therefore they are looking for ways to assess how consumers would react to new business models.
