BALANCE – Demand-Oriented Analysis of Load Behaviour for the Adaptation of Sustainable and Smart Energy Supply
An uncontrolled charging process (top) and a charging process optimised for renewable energies and thus a minimal CO2 share in the electricity mix (bottom).
In BALANCE, we use extensive data on charging processes and external incentives to charge in a way that benefits the energy system and to compare operational management concepts quantitatively.
With the rapid expansion of renewable energies and the market ramp-up of electromobility, operators and users of private and semi-public charging infrastructure (LIS) are facing new challenges. This is precisely where the BALANCE innovation project comes in: The development of advanced analysis techniques and the use of IoT data from charging processes, decentralised consumers and generators enable intelligent forecasts. These create the basis for demand-based control of charging processes and home energy management systems (HEMS) - an important step towards grid stability, energy efficiency and the integration of renewable energies.
A particular focus of the project is on optimising charging behaviour in the private and semi-public sector, where, according to a recent study, around 68% of energy is used for charging electric vehicles. This is where there is the greatest potential for flexibility and load shifting in order to actively contribute to stabilising the electricity grid.
The consortium, led by chargeIQ GmbH, is working on modular, platform-based solutions together with partners Mondas GmbH, Stöhr GmbH, the University of Stuttgart (Institute of Business Administration, Department VIII) and Fraunhofer ISE. These include dynamic load management, PV surplus charging, predictive analytics for early fault detection and the integration of various HEMS solutions via a service store. In future, users will benefit from more freedom of choice in HEMS software and sustainable utilisation of existing hardware, which conserves resources and saves CO₂.
Fraunhofer ISE's focus in the project is on the further development and application of our smart charging solution OptiCharge around the use cases maximum utilisation of the local renewable energy share according to EnergyCharts API and grid congestion optimisation using Stromgedacht API. We are also developing an analysis framework that makes various optimisation strategies for real charging processes quantitatively comparable.
Through close cooperation between industry and science, BALANCE is developing innovative, practical solutions that not only fulfil current requirements, but also actively shape the future of electromobility and sustainable energy supply.
