"econnected. From Aachen to Leipzig, from Allgäu to Sylt."
Seven municipal utilities - Aachen, Allgäu, Duisburg, Leipzig, Osnabrück, Sylt, and Trier - founded the "econnect Germany" research association. Since January 2012, they have been working with partners from industry and research under the econnect Germany umbrella at seven locations in Germany.
As part of a federal research project, econnect field trials started on September 26, 2014. Ten residential customers of STAWAG each received an electric vehicle to use in their daily lives.
The information on loads generated by the charging stations and the electric vehicles are sent to the STAWAG control system via an open interface which, in combination with additional master data, enables monitoring and control by the control system. For this purpose, the data entry of the PSIcontrol system has been expanded and the appropriate monitoring functions have been realized.
"smart area – integration of decentralized generation of renewable energies in the supply infrastructure."
The concrete objectives of the "Smart Area Aachen" project are the design, operation, and research of a "Smart Grid" in the city of Aachen. In addition to STAWAG as consortium leader, twelve industry and research partners contribute to the project, including the PSI Energy EE business unit. The first project of the "Smart Area Aachen" consortium started in mid-2012. Each individual project is scheduled to run for four years.
"Self-learning information structures for crisis management shown for electricity supply"
The focus of the infostrom research project is the technical support of inter-organizational cooperation and system restoration in case of power outages. All technologies, concepts, and methods for improving the inter-organizational communication, information, and coordination processes have been developed and analyzed in cooperation with the University of Siegen, Fraunhofer FIT, PSI, RWE, SAP Research, and the counties of Rhein-Erft and Siegen-Wittgenstein.
"Simulation of energy networks: scenarios for the future supply of electricity, gas, and district heating."
One of the present and future challenges is to utilize and expand the network reliably and efficiently. This will require a holistic analysis of the entire energy cycle in electricity, gas, and heating district networks. The energy industry is not yet fully prepared for this task today. Monitoring and data exchange across networks are not yet fully available. The joint project MathEnergy is designed to overcome this issue.
The Project includes the model reduction and estimation of uncertainties for the energy networks currently undergoing a process of transition and focuses on electricity and gas as well as the design of cross-network efficient simulation and analysis models and model-based concepts for monitoring, control, analysis, and data exchange.
“Can outages be bridged by using renewable energies only?”
The objective of the LINDA project is to check to which degree electricity can be restored locally by using only renewable energies in case of outages. The first field trials have been completed successfully. The project complements the existing national-level strategies of transmission system operators to ensure supply in case of an outage.
The objective of the IDEAL project (impedance controller and distributed congestion management for autonomous energy flow coordination, funded by the German Federal Ministry for Economic Affairs and Energy) is the development of a responsive congestion management system for high and medium voltage networks. In this project, the required communication and interaction between agents, impedance controllers, central control centers, and distributed flexibility requirements based on new networking concepts is researched and tested. The project is scheduled for completion in July 2019. The development system will later be evaluated in field trials.
