RWTH Aachen Study Overview:Modular power flow control application in GermanyIntroduction from Smart Wires June 2020

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

SmartValveTM - Key attributes of Modular Power Flow Control

Main Application: Leveraging the existing or new network

Before Smart WiresSimplified planning scenario predicts future overload

Smart Wires in “Push” ModePower is pushed to alternate lines with spare capacity, resolving overload

Smart Wires in “Pull” ModePower is pulled onto lines with spare capacity, resolving overload

Flexible Physical Deployment: Leveraging Modularity

Solution can be easily and quickly expanded (or contracted) to adjust topology

Increasing the efficiency of the Grid: Today and Tomorrow

1. Increase efficiency of existing grid – will see in study

2. Fast delivery mops up current issues

Tomorrow

1. Improved impact of new investments – reduce risk of under utilisation of new projects

2. Help manage complex system issues as they emerge

3. Integrates smoothly with other technologies as they are introduced

Introduction

Results

Summary and Outlook

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
