RWTH Aachen Study Overview:Modular power flow control application in GermanyIntroduction from Smart Wires June 2020
© 2018 Smart Wires Inc. Company Confidential© 2019 Smart Wires Inc. Company Confidential© 2020 Smart Wires Inc.
The SmartValve: is a modular Static Synchronous Series Compensator (M-SSSC)
Power Electronics Technology: that injects a controllable voltage (leading or lagging) in to a circuit, either manually or automated controls.
Main application: to pull power towards or push power away from the circuit on which they are installed
Flexible Electrical Deployment: Same unit can be used at any voltage in network; scaled or rescaled to meet the need
Flexible Physical Deployment: Substations, on towers, or on mobile platforms, light and compact
Fast deployment: 1 Year deployment possible from order to installation
High Security: Combined capability offers naturally high reliability and redundancy
Lifetime: 40 year plus

Redispatch and Curtailment Volumes
Modularity and flexibility in positioning given with SSSC may double the benefit regarding redispatch volumes compared to a PST with same capacity (comparison of Grid Delay 4 SSSC and Locational sensitivity)
Further aspects to be investigated in future
Existing interdependencies between the dimensioning of SSSC and dynamic line rating must be considered -
Reduced redispatch volumes expected
but higher loading of SSSC possible
Introduction of the Flow-Based market simulation in accordance with the Clean Energy Package leads to increased redispatch volumes due to the given minRAM
No consideration of other than German grid congestions as well as no consideration of reactive remedial measures, which possibly result in lower redispatch volumes
Positioning of SSSC relies on study results and expert knowledge; might be even more beneficial with the usage of a positioning heuristic

Annual average investments in grids to 2050
50% electrification would require such amounts of annual investment over the full period between 2020-2030
➢More RES
➢More electrification
➢Different types of loads (e.g. EVs)
➢More restructuring
➢ Can maximise grid use by overcoming system limits
➢ Accelerate renewables’ integration
➢ Reduce curtailment
The technologies are there and proven; still not widely deployed

• Direct current links equalise the current
exchange between North and South:
Additional HVDC-Link with 4GW to the NRW
• Offshore connections points moved to the

The conventional power plant support
the system security by
1. Inertia
2. Reactive power
3. Short circuit power
The ability to support the system behaviour by
the large conventional power plants has to be
provided by large number of distributed
renewables as well
FUTURE: decreasing number of conventional
power plants in the network
In order to keep the system security the
