InnoDC has published its work on reducing errors in alternating current (AC) & direct current (DC) measurements, as well as with the Wales-based Angle-DC project. And InnoDC features for a 2nd time in European Energy Innovation. See below for details.

State Estimation for Hybrid VSC Based HVDC/AC Transmission Networks, published in Energies. |
|
Transmission system operators use supervisory control and data acquisition (SCADA) to monitor and control power networks. Sometimes the collected measurements from the network are received corrupted. Therefore, a state estimator tool in the SCADA is used to reduce the noise (error) in these measurements and deliver a better presentation of the system states (e.g. voltage magnitude). This process became more complicated with the different AC and DC network topologies (layouts). Motaz Ayiad (UPorto & Efacec) presents a unified state estimator that reduces the errors in the AC and DC measurements simultaneously. |

Analysis and Control of MVDC Demonstration Project in the UK: ANGLE-DC, published in Distribution & Utilization. |
|
As household and industry electricity demands increase, uncontrolled power flows put the system at risk. One option to reduce risk is to convert AC lines into DC operation. The Angle-DC project, on the Isle of Anglesey and in North Wales, is creating a novel reinforcement technique to convert an existing 33 kV AC circuit to DC operation. Gayan Abeynayake‘s paper summarises Cardiff University’s work as Angle-DC’s academic partner, highlighting operation and control aspects, as well as reliability concerns. |

The article highlights how InnoDC shares its work globally and to as wide an audience as possible. Read it here. |
We’ll provide more InnoDC research summaries in 2021. In the meantime, you can find the publications on the website’s journals page.
