Transformational Power Flow Control Technology Unlocks Cross-Border Electricity Capacity in Southeastern Europe
OCTOBER 21, 2021
A transformational grid enhancing technology, SmartValve™, has been successfully commissioned in Greece, marking the second deployment of power flow control technology by IPTO. By intelligently controlling the flows of power across the network, this technology can unlock available cross border interconnection capacity between Greece and Bulgaria.
The project is part of the FARCROSS Horizon 2020 project, which aims to increase cross border electricity flows across South-Eastern Europe and improve market coupling by leveraging innovative solutions.
Announcing the successful installation, Mr. George Papaioannou, Director of IPTO’s Research, Technology & Development Department, said “Innovative projects like this are key to Europe’s energy transition and we are delighted to be collaborating with Smart Wires and ESO to improve utilization of our existing networks.”
Mr. Mark Norton, Smart Wires’ Vice President, Business Development Europe commented “Increasing interconnection capacity across Europe has been identified as a necessary enabler of market integration and reaching a decarbonized future.”
“This project will do just that –significantly increasing interconnection capacity and heralding a new era of solving grid challenges with rapidly deployable, flexible next-generation technology,” Mr. Norton said.
The technology works by pushing power off overloaded lines and pulling power on to underutilized lines; balancing power flows across multiple lines and relieving internal constraints that limit cross-border flows. The SmartValve technology was installed on the 150kV Nea Santa –Iasmos line.
Mr. Konstantinos Plakas, Research Electrical Engineer of IPTO’s Research, Technology & Development Department, said “Studies showed that additional capacity could be made available with the use of this technology”.
Mr. Christos –Spyridon Karavas, Senior Engineer and Technical Consultant of IPTO’s Research, Technology & Development Department, commented “This technology could potentially increase the capacity of the existing network andprovide greater operational flexibility to manage constraints.”
This project builds on the previous Flexitranstore H2020 project which utilizes smart grid technologiesto address the challenges of large-scale renewable energy integration andincreasing grid flexibility. In this project, Smart Wires’ mobile power flow technology was initially installed in collaboration with IPTO in Greece and has recently been redeployed to Bulgaria with ESO to explore further uses cases of this technology to address some of the region’s most critical needs.
FARCROSS aims to address the challenge of regional cross border electricity transmission by connecting major stakeholders of the energy value chain and demonstrating integrated hardware and software solutions that will facilitate the “unlocking” of the resources for the cross-border electricity flows and regional cooperation. To achieve its energy goals EU needs to establish a geographically large market by initially improving its cross-border electricity interconnections. A geographically large market, based on imports and exports of electricity, could increase the level of competition, boost the EU’s security of electricity supply and integrate more renewables into energy markets. Electricity should, as far as possible, flow between Member States as easily as it currently flows within Member States, so as to increase sustainability potential and real competition as well as to drive economic efficiency of the energy system.
