Concentrating Solar Power (CSP) technologies are important for climate-neutral energy supply. Their high energy storage potentials enable projectable energy supply and in cooperation with photovoltaics and wind energy a cost reduction of the basic load.
In solar power tower systems, a large number of sun-tracking mirrors (heliostats) concentrate the solar radiation onto a receiver at the top of a tower. A heat transfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine generator to produce electricity. A typical commercial power tower system with around 100MW has a total reflecting surface of around 106m2. With a mirror size of 10m2 to 150m2 this correlates with up to 100,000 heliostats. Currently, every heliostat is controlled individually and each is connected to the control station with one power and one data wire.
Since there are extreme conditions with high material requisition inside the solar receiver, reliable and time-critical control of the heliostats is needed. At the same time, the solar thermal power unit is subject to high-cost pressure. To reduce the cost of wiring the heliostats, while maintaining a reliable control system, a convenient wireless communication solution is discussed.
In this context, 5G mobile networks represent a promising technology. Against the background of the requirement profile for massive and critical Machine Type Communication, 5G networks assure reliable communication for the large number of participants. Additionally, parallel wireless communication within the same 5G network can be used to deploy monitoring and maintenance devices inside the heliostat field. The aim of the research project „5hine“ is the identification, analysis, and development of technical and economically efficient solutions for 5G campus networks with a focus on solar power tower systems.
The team of the optimization and control group at ie3 will work on new methods to enable automation and control via 5G networks.

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.
