Energieflussoptimierung in Smart Grids mittels intelligenter Netzkomponenten

The fundamental transformation of the German energy landscape as part of the energy turnaround is associated with a considerable increase in volatile feed-in from decentralized energy gen­era­tion units into the distribution grid. This change causes bidirectional load flows at the low and medium voltage levels and new challenges arise in the distribution networks. Normative limits regarding voltage level and voltage quality must be satisfied while integrating the increasing number of decentralized gen­era­tion units and storage facilities to guarantee a stable grid operation.

The Stadtwerke Bochum Netz GmbH offers a small distribution network section within the proj­ect frame­work for testing new load flow optimization algorisms. This section will be equipped with modern and smart components and thus transferred as a smart grid. An electronically controllable local substation transformer developed by ct.e – Control technology Engineering GmbH will be used. The In­sti­tute for Energy Systems, Energy Efficiency and Energy Economics (ie³) of the TU Dort­mund Uni­ver­sity contributes with its experience in researching and designing protection and smart grid automation functions as well as their implementation on standardized hardware platforms. Together, a control strategy will be developed that allows the optimization of the energy flows in the Smart Grid. This implementation requires detailed system analyses, computer-aided simulations, and in particular, highly complex stability considerations. Furthermore, the results collected in the proj­ect will be applied to the above-mentioned smart grid and tested concerning their effectiveness.

The energy flow-oriented control of the distribution grid components is intended in particular to increase the degree of utilization of the regenerative producers and thus to increase the proportion of regenerative feed-in energy in the German energy mix. This results of this re­search have direct and indirect ef­fects on the emission of CO2 and other climate-relevant emissions.

Based on many years of experience in its re­search areas, ie³ has the necessary know-how to apply suitable methods for determining the grid state, to implement control algorithms, and to integrate them into the planned concept as a superordinate control strategy. Furthermore, the laboratories of the ie³ have the technical means to simulate analogue networks and to perform realistic network simulations in real-time. Thus, the ie³ fulfils the essential requirements for the simulation of the distribution network section, both in hardware and as a di­gi­tal simulation model, to determine optimal measures for energy flow adjustment.

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.

The facilities of TU Dort­mund Uni­ver­sity are spread over two campuses, the larger Cam­pus North and the smaller Cam­pus South. Additionally, some areas of the uni­ver­si­ty are located in the adjacent "Technologiepark".
