Title : Resilience modelling for smart neighborhoods
Building E1 3, Lecture Hall HS 001
The use of renewable energy in houses and neighborhoods is very much governed by national legislation and has recently led to enormous changes in the energy market and poses a serious thread to the stability of the grid at peak production times. One of the approaches towards a more balanced grid is, e.g., taken by the German government by subsidizing local storage for solar power.
While the main interest of the energy operator and the government is to balance the grid and still have positive revenues, thereby ensuring grid stability, the main interest of the client is twofold: the total cost for electricity should be as low as possible and the power supply be as resilient as possible in the presence of power/grid outages. Clearly, these two objectives highly depend on the availability and capacity of local storage, and the overall strategy followed by the local controller.
We present a Hybrid Petri net model of a house that is mainly powered by solar energy with a local storage unit and subsequently analyze the impact of different storage strategies on the resilience of the power supply and the overall cost of electricity, for different production and consumption patterns.
