Challenge / Goal
The continuously increasing prevalence of variable renewable energy sources, such as wind and solar, along with an increasingly intricate consumption spectrum, such as smart home appliances or e-mobility, are making the management of modern building networks ever more complex. At the same time, highly granular control of volatile energy flows holds great efficiency potential and thus the potential to reduce emissions. As one of many use cases, an electric car can be preferentially recharged with solar power while parked and the solar power can be redirected to a storage unit immediately after the process of recharging is completed. This type of control, however, is extremely intricate and not feasible on a larger scale without the use of special software.
Digital load management allows energy to be directed to where it is needed in real-time. To fully utilise the efficiency potential of this technology, it is necessary to modify the software according to the respective site. This involves supplementing the central load management system with a specific control hierarchy. These include prioritisation of producers and consumers. Regarding the above use case with an electric car, PV system, and storage unit, this hierarchy would mean that the charging of the car with solar power is the priority, and the filling of the storage is the second priority.
