New opportunities especially arise in the intersectoral analysis, for example the combination of power and heat (cogeneration).

Business models
Due to the rapid development of renewable energy sources, energy efficient technologies and political measures have fundamentally changed the conditions for the energy industry. Many established business models are obsolete, while the decentralized energy supply and innovative technical solutions are unlocking new possibilities. The Fraunhofer Energy Alliance supports its customers in the development of new business models by analyzing market and service opportunities considering regulatory, social and technical conditions.

These include concepts for management and energy services, demand-side efficiency strategies, storage applications in the power grid and the usage of flexibility options.

Energy supply structures
The transformation from a centralized to a decentralized supply structure requires meeting various technical challenges. Experts at Fraunhofer support their customers by developing new system concepts for the energy supply considering different expansion strategies for renewables. In this context, the design and optimization of power, heat and storage systems in the course of the increasing interconnection of different fields and changing conditions and demand structures are of particular importance.

In addition to urban supply structures, the Fraunhofer Energy Alliance also develops solutions for rural areas. Isolated grids on the basis of renewables provide a promising alternative to the traditional grid integration. Remote villages in developing countries or inaccessible alpine huts can benefit from device-integrated solar modules, electricity from biomass and micro fuel cells to self-sufficiently operate electrical devices.

A further focus is the simulation and condition monitoring of new supply structures and the development of decentralized and centralized plant concepts. To ensure the stability of new supply structures, the Fraunhofer Energy Alliance offers various methods for system tests. These include investigations on the electromagnetic compatibility, conformity and interoperability as well as testing of the grid integration.

The security of supply in new supply structures is crucial. In this respect, experts at Fraunhofer offer solutions to guarantee quality and reliability.

Energy in digital context

Digitization will play a major role in the future energy system and will profoundly change the energy sector. Large amounts of data are not only the core of digitization but also the basis for the future energy system and new business models. The Fraunhofer Energy Alliance is researching methods for collecting and transferring data in the energy system. In addition, we support our customers in the analysis and usage of energy data.

Energy data system
Energy data are used for controlling and operating electricity grids as well as for processing business transactions. The above mentioned areas each have different requirements: low latency and highest reliability in technical operation – cost-effective usage of available IT infrastructure and data security for commercial transactions. Both are closely interlinked. Therefore, the Fraunhofer Energy Alliance is researching on IT infrastructure architectures meeting the high requirements that arise due to the decentralization of energy supply. Most important aspects are data security and data protection, resilience (durability) and low costs. For the components of different manufacturers to exchange data, interoperability and standardization are essential. The implementation will be guided by recent research findings on the Internet of Things (loT) that can be used flexibly in the energy data system.

Energy data collection
Energy data are the basis of digital methods and business models. But first they need to be collected. Energy self-sufficient sensor technologies measure physical parameters efficiently. Sensor networks with lowest energy consumption collect data and pass them to gateways. In this context, intelligent measurement systems like Smart Meter can make a crucial contribution, as they can record the consumption and generation of electricity, cold, heat, gas and water in a reliable, high-availability architecture.

State-of-the-art measurement devices like the Phasor Measurement Unit (PMU) allow for precise condition monitoring of smart grids. These devices can synchronously measure the load in the grid und analyze errors.

The Fraunhofer Energy Alliance offers its customers reliable solutions for data collection to implement business transactions. They are the basis for the data pool, which allows for extensive utilization with regard to energy efficiency analysis, customer service and market integration.

Exchange of energy data
As the demands on electric grids are increasing, data exchange processes also become more complex. Modern, standardized interfaces allow for data streams to be implemented in a reliable way and ensure a permanent exchange of information. For future grid operations, standards like IEC 61850, IEC 61970, IEC 62351 and IEC 62325, that only describe a part of the interface requirements, are indispensable. Especially when using generally available communication lines, data security and availability are of utmost importance. Moreover, experts at Fraunhofer are working on new wireless procedures for narrowband communications to use the sensor data from the distributed energy grid in a cost-effective way.

The Fraunhofer Energy Alliance offers suitable solutions to ensure a safe and trouble-free data exchange between all participants.

Energy data analysis
An important benefit of the collected and transmitted data is the option to analyze them. In the easiest case, links generate alarms and alerts. Larger amounts of data provide a significant added-value in terms of preparation, aggregation and representation. While Data Analytics is the process of analyzing values of the past, forecasts will have a much larger influence in future. Systems of the Fraunhofer Energy Alliance predict energy demands via model-based methods depending on season, weekday, time and other relevant parameters like meteorological constraints. The same is also true for Condition Monitoring. In this approach, operating data are collected in order to identify a significant change which is indicative of a developing fault.

Usage and application of energy data
The combination of ICT methods and procedures leads to improved and innovative applications. The Fraunhofer Energy Alliance also deals with the effects of flexible, fluctuating tariffs on electricity suppliers and their energy procurement strategies. Experts at Fraunhofer develop solutions for a comprehensive energy data management. Demand-side management systems play an important role in this context, as the energy consumption in these systems is controlled intelligently. Demand-response systems, in the form of Smart Energy Gateways, which allow for a decentralized optimization of use via predictive methods are also of great importance.

With regard to the growing grid requirements within the deregulated energy market, experts at Fraunhofer offer market players TÜV-proven (German organization for technical safety and certification) and comprehensive IT solutions for power usage and accounting grid management. At grid level, the institutes realize field trials on real grids for their national and international partners, which can be complemented by simulations. Energy management systems use the collected data to control different generators, storages and loads within the grid.

Virtual power plants are used for an integrated operational management of decentralized energy sources. These power plants aggregate many decentralized generators, storages and loads to one flexible power plant which sells the generated energy at the best price. During these processes, we closely collaborate with energy suppliers who pursue innovative business models.

Due to the high level of complexity, the rapid and precise condition assessment of networked infrastructures is more important than ever and will gain further importance in the future. New methods, which are based on linear algorithms, ensure faster and more precise results than conventional algorithms for a minimum investment.

The Fraunhofer Energy Alliance also offers trainings on the topic “Digitization of the energy world”.
