2020 Dec – Measurement errors, Angle-DC & InnoDC’s reach

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.
Authors: Motaz Ayiad, Helder Leite and Hugo Martins

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.
Authors: Gayan Abeynayake, James Yu, Andrew Moon and Jun Liang.

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.

Emily Maggioli, Vaishally Bhardwaj, Wei Liu and Luis Orellana designed and wrote a feature in European Energy Innovation Winter 2020.

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
