Another significant achievement in the LACISE project – congratulations to Rolāns Karpovs!
On 15 June 2026, Rolāns Karpovs successfully defended his Bachelor’s thesis titled “Analysis of the reliability level of forecast data for a dynamic line capacity estimation approach”, completed within the professional Bachelor’s study programme “Smart Power Engineering” at Riga Technical University.
As electricity demand and the share of renewable energy sources continue to increase, the efficient utilisation of existing power transmission infrastructure is becoming increasingly important. Dynamic Line Rating (DLR) technology enables transmission line capacity to be increased by using real-time and forecasted meteorological data. However, its effectiveness strongly depends on the accuracy of these forecasts.
The Bachelor’s thesis evaluated the reliability of D-1 and D-2 forecasts by comparing forecasted transmission line ratings with actual operational measurements. The results demonstrate that there is no universally optimal forecast group. Instead, selecting the most appropriate forecast requires balancing transmission system security with the efficient utilisation of existing transmission infrastructure.
The thesis was supervised by Professor Anna Mutule in collaboration with Andris Eglītis, industrial advisor from AS “Augstsprieguma tīkls”.
We are proud of this achievement and wish Rolāns continued success in his professional career!
The work was developed with the support of the LACISE project within the framework of the Swiss-Latvian cooperation program “Partnership in Applied Research.” The LACISE project (2025–2029) aims to address the most important energy challenges and prepare the next generation of scientists. It will promote long-term and multidisciplinary cooperation between Latvian and Swiss researchers, combining knowledge in materials science, chemistry, energy, information technology and artificial intelligence.
