1. 1. Decoding the surface code using graph neural networks

   University essay from Göteborgs universitet / Institutionen för fysik

   Author : Moritz Lange; [2023-10-17]
   Keywords : ;

   Abstract : Quantum error correction is essential to achieve fault-tolerant quantum computation in the presence of noisy qubits. Among the most promising approaches to quantum error correction is the surface code, thanks to a scalable two-dimensional architecture, only nearest-neighbor interactions, and a high error threshold. Decoding the surface code, i.e. READ MORE

4. 3. System impact of micro-production

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Annie Haraldsson; [2023]
   Keywords : Fault ride through; LVRT; micro-production; solar production; photovoltaics; fault simulation; network modeling; power system disturbances; PMU-registrations; fault analysis; Technology and Engineering;

   Abstract : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG.

5. 4. FEATURE EXTRACTION AND CLASSIFICATION OF TRANSIENT FAULT RECORDS

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Emanuel Bjurhager; [2023]
   Keywords : ;

   Abstract : As the power distribution system grows and more sensors are added, more data is created every day. This data can be crucial for finding faults, but there is now so much data that it ends up being unused. This presents a valuable opportunity to gain crucial insights into the continuously expanding and increasingly complex power distribution system. READ MORE

6. 5. Substation digitalization and fault isolation : A study of the influence of degree of digitalization to regulatory indicators in the power grid

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Ili Atalla; [2023]
   Keywords : ;

   Abstract : With changes in the energy sector, more demand is set on the power grid as electricity consumption is seen to increase and more decentralized renewable energy production is connecting to the grid. Svenska Kraftnät, electric system transmission operator in Sweden, describes the importance a more secure operation of the power system. READ MORE
