Decentralised Energy Management

SoLAR aims to demonstrate how to maximize the use of fluctuating renewable energies in a decentralized energy system in a particularly simple, generally accepted and economical way. This demonstration project will show under real conditions how renewable energy shares can be highly increased and carbon reduction reduced at a district level, by implementing a modular and scalable energy management under real-life conditions.
The pilot site in Allensbach, Germany, comprises a residential real estate energy system of 10 buildings, coupling heat and power vectors (HP, CHP, thermal storages, batteries, PV).

Virtual Demonstration

In Phase 1, EIFER has developed a virtual demonstrator of the 22-dwelling pilot site that has shown successfully the feasibility of decentralised energy management. This virtual demonstrator is a highly realistic simulation of the real pilot, making use of latest modelling techniques such as agent-based and multi-method approaches.

Improved Use of Local Energy

The current use case of the energy management system has achieved to maximise self-consumption of the site by 13%, making best use of local produced energy; a peak reduction up to 36% alleviating the distribution grid; and a cost reduction of 2-5ct/kWh allowing the end consumer to benefit from advantageous tariffs.
In Phase 2, the real demonstration is being carried out and verifying the concept under operational conditions (2019-2021). The virtual demonstrator is connected to allow for a continuous optimization of the system.
