At various levels it is recognized that significant changes are needed to enable and accelerate the energy transition. One of the ideas is to develop regions which are autonomous or self sustaining in their energy needs (=autarkic). This idea matches society's desire for energy independence on a small and manageable level, which above all is also sustainable.
For the energy infrastructure this implies, that such an area has no (or very few) connections (for energy exchange) to the surroundings. At any given time, the energy produced locally should match local energy consumption. Local conditions, such as space, wind speed and solar radiation must be taken into account for the generation of energy. These conditions vary from year to year. In addition, different types of consumers must be considered, each with their own realistic energy consumption, such as homes, shops, offices, schools, restaurants, businesses and industry.
With the EAST simulation tool, energy flows in an area can be analysed and quantified. The purpose of this simulation tool is to understand what it takes to create energy-independent (self-sufficient) regions or districts (such as villages or towns). The simulation model can be adapted to different situations, is modular and expandable and the results are transparent, in order to serve as a starting point for discussions, communication and making plans.
- Simulation of a whole year, on hourly basis
- Variations from year to year (realistic randomness)
- External weather conditions based on local climate and seasons
- Different types of consumers, producers, storage and conversion systems
- Three energy sources: electricity, gas and heat
- Expandable, scalable, adaptable to local conditions
- Time profiles of energy production, consumption, storage and conversion
- Bottlenecks in energy balance
- Cost of energy
- Energy scenarios to achieve energy independence
