An increasing number of private households are becoming producers of renewable energy. As a significant technical and financial outlay is required in order to store and/or transport such decentrally generated energy over greater distances, it is beneficial from an economic perspective to utilize this energy both locally and promptly. However, this requires the ability to be able to deal with local excess production at short notice using, for example, an electronic trading platform.
The objective of "PeerEnergyCloud" is to research and develop cloud-based technologies for such a platform. This includes the establishment of a virtual marketplace for local power trading as well as the design and development of innovative recording and forecast methods within a so-called "micro grid."
The integration of local sensors and actuators at the end-user locations - via a specially secured fiber optic cable - enables the "smart micro grid cloud services" to access usage data in real-time which can be used for the purpose of generating forecasts. Additional energy-related services (e.g. energy auditing, object protection/building monitoring, etc.) can be offered via third-party providers where the consumer allows selected data to be used for other purposes. A specific case, which relates to a micro grid in the city of Saarlouis consisting of approximately 500 housing units and numerous photovoltaic facilities, is currently being reviewed within the scope of the project.
Trust im Fokus - the local peer-2-peer energy trading platform is based on highly differentiated and individual load profiles which provide a number of significant advantages: the urban network structures can be used optimally and energy feed-ins to cross-regional networks can be avoided; thereby relieving the load on these networks.
An energy marketplace and basic services are also to be developed within the scope of this project, and new incentive models will ensure all participating partners will be able to benefit from the added value that is created. Particular attention is being paid to the protection of personal data as well as security in relation to data entry, transmission and storage. The problem of "trustability" of the service providers in the cloud will be handled using new procedures for data distribution, access right rules and partial encryption of the data.
