A major research field within this research group addresses the operational planning and management of active and flexible distribution grids. For the integration of decentralized energy resources and new consumers on distribution grid level, the existing grid infrastructure and its transfer capacity is not appropriate for current and future grid utilization. The aim of the operational planning and management strategies for distribution grids is therefore to use the existing grid infrastructure more flexible and efficiently and where reasonable avoid additional grid expansion.
The basis for operational planning and management strategies is the estimation of the current or future grid state. In most medium and low-voltage grids there is only a small number of nodes with are equipped with measurement devices. Therefore, algorithms for the placement of additional measuring points and the incorporation of further data sources for the estimation of the system state are investigated. In the next step the transferability of methods for state estimation to the distribution grid are tested and the applicability of new algorithms for state estimation is analyzed. Uncertainties due to measurement and pseudo measurement data are taken into account and finally their effects on the system state accuracy are examined.
With monitoring or forecasting information about the grid state, the medium and low voltage grids can be utilized more efficiently and grid congestions and voltage range problems can be solved in a targeted manner. In addition, algorithms for the aggregation and dispatch of active and reactive power feed-in of flexible feeders, consumers and storage devices are developed. This flexible power can be used, for example, to eliminate grid congestions in overlaid grid levels and to provide ancillary services.
Finally, concepts for the integration of flexible power from the distribution grids into electricity markets are being developed. For this purpose, the roles of the individual participants in the energy system are first defined and a suitable market design is developed. Based on this, operative measures for the use of flexible power in grid operation management are derived and recommendations for action are given to the individual market participants.

Location & approach
The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is "Dortmund-Eichlinghofen" (closer to Campus Süd), and from B 1 / A 40 "Dortmund-Dorstfeld" (closer to Campus Nord). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.
To get from Campus Nord to Campus Süd by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at Campus Nord and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.
TU Dortmund University has its own train station ("Dortmund Universität"). From there, suburban trains (S-Bahn) leave for Dortmund main station ("Dortmund Hauptbahnhof") and Düsseldorf main station via the "Düsseldorf Airport Train Station" (take S-Bahn number 1, which leaves every 20 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.
You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station "Stadtgarten", usually lines U41, U45, U 47 and U49. At "Stadtgarten" you switch trains and get on line U42 towards "Hombruch". Look out for the Station "An der Palmweide". From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop "Dortmund Kampstraße". From there, take U43 or U44 to the stop "Dortmund Wittener Straße". Switch to bus line 447 and get off at "Dortmund Universität S".
The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on Campus Nord. One ("Dortmund Universität S") is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the "Technologiepark" and (via Campus Süd) Eichlinghofen. The other station is located at the dining hall at Campus Nord and offers a direct connection to Campus Süd every five minutes.
