ICT networking platform

The energy transition requires Information and Communications Technology (ICT) that enables communication within an increasingly decentralised energy system based on standardised interfaces. It is only in this fashion that we can create a smart and secure network between various players and efficiently use the generated data. Within this workstream, we are therefore developing basic IT services, open market access for new flexibility providers and make data streams transparent for start-ups and consumers.

Basic services for networking within the digitised energy system

Cooperation between new and old players in the energy system of the future will only be efficient and reliable if based on secure data exchange and common services. In this project, Fraunhofer FOKUS is therefore developing the required IT basic services and creating a data and service market where data can for instance be anonymised in accordance with the applicable data protection law and be provided for further analysis. Authorised parties can access data and services via a portal as well as standardised interfaces. To ensure that this interaction also complies with the law and is protected against attacks by unauthorised parties, FOKUS is developing a standard-based IT security concept as part of the project.

Innovative process platform

50Hertz’s innovative process platform aims to create decentralised flexibility options in the form of small-scale conventional and renewable generating units and switchable or shiftable loads. In this project, we study to what extent this flexibility can be used in support of grids and systems. More specifically, we integrate decentralised flexibility options into the processes for grid congestion management via the flexibility platform. At the same time, we continue to develop operating reserve processes so that we can take into account the specific aspects of virtual power plants and aggregators and improve their access. Finally, we improve forecast methods for solar power generation using smart meter data to make realistic self-consumption predictable and improve the forecast quality for marketing and system security.

Open Data Portal

In this project, Stromnetz Berlin is developing its existing grid data portal into an open data portal together with Fraunhofer FOKUS. This portal provides detailed public data as well as private data in an anonymised and aggregated form, for instance about individual city districts or user groups. This also allows us to exploit new data sources and integrate them into the open data portal. In order to promote new applications and business models through this expanded database, we organise several community events, such as Hack Days, with programmers, creative individuals and young start-ups. At each event, we award prizes for the best exploitation ideas for the new open data offerings and applications and support the implementation of selected ideas.

Market and consumer platform

In this project, Pumacy is designing a market and consumer platform with search-based big data applications. In order to evaluate the practical feasibility of the approach, we are implementing and studying different use cases. This should also result in new consumer and operator models. The technological core of the platform consists of search-based applications that can equally index, aggregate, normalise and visualise the structured, semi-structured and unstructured data. This makes it possible to analyse the growing data volumes in the energy system of the future in a controlled and easy manner. Different use cases are shown by special demonstrators.
