Redispatch 3.0


Motivation

With the high penetration of distributed energy resources, the regulatory framework and grid operation procedures were adjusted in the amendment to the Grid Expansion Acceleration Act (NABEG 2.0). In this context, involving Distribution System Operators (DSOs) in congestion management is an important step in implementing the so-called “Redispatch” procedure. Redispatch aims at avoiding grid congestions across all voltage levels and tries to make grid operation more efficient, economical, and resilient.

In Redispatch 2.0, renewable energy sources and Combined Heat and Power (CHP) plants with a peak power larger than 100 kW as well as controllable loads can be remotely controlled by grid operators. In the future, forecasting of grid congestions will be carried out by Transmission System Operators (TSOs) and DSOs with the corresponding dispatch potential and requirements to enhance transparency and flexibility potentials across all voltage levels.

Goal

The project “Redispatch 3.0” aims at improving the integration of low-voltage plants as well as the cooperation and exchange of information between DSOs and with TSOs. The goal is to extend existing concepts from Redispatch 2.0 and implement, test, and evaluate developed approaches in practice via selected field tests.

ie³ Involvement

In this context, ie³ participates with two groups in the project: Distribution Grid Planning and Operation as well as Optimizazion and Control. The latter will develop optimization-based algorithms for scheduling congestion-free operation at the medium and low-voltage level. The former group will develop a framework for schedule validation in the agent-based simulation tool SIMONA. Integrating and testing the developed prototypical software in a cloud-based environment is an additional focus of the activities.

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".
