Kasper Emil Thorvaldsen

About

I work at NTNU, Department of Electric Energy (NTNU IEL) as an Adjunct Associate Professor (20%), within the topic "The transition to a sustainable energy system". Primarily I am involved in teaching and education within the study program Energy and Environment (MTENERG), but I will also be involved in different master thesis topics for the 5th year students at the study program. My main work is as a research scientist at SINTEF Energi, Energisystemer.

I consider myself to be an outgoing, easy to talk to and positive person. If you have some questions regarding courses or master topics, please feel free to reach out to me :)

Competence

Within research, I primarily work on optimization and programming of the energy system, to look into the future solutions to better make use of flexibility, primarily electrical flexibility. My core competence is considered to be:

Python Programming
Optimization techniques within the energy system
Analytical methods to investigate flexibility, and the value of flexibility
Long-term operational planning of the energy system and flexible resources
Stokastic dynamic programming (SDP)

Education

Msc, Energy and Environment at NTNU: 2013-2018
- I specialized within the techno-economic aspect of the energy system, and wrote a master thesis about the role of battery storage towards energy and reserve capacity markets. Using SDP, I looked at the long-term strategy of operating the battery.
PhD NTNU IEL: 2018-2022
- I have a PhD within long-term oprational planning of the energy system within buildings. The work looked into how we can incorporate long-term price signals and represent them for short-term operational models. This will enable more global and optimal use of the flexible resources available, considering both the here-and-now value and the long-term future value of these resources.

Publications

Much of my research is based on studying the techno-economic potential that flexibility can provide in energy systems. This involves developing and using optimization models to represent the energy system and investigating the benefits and opportunities that flexible resources can offer. These resources range from small-scale flexibility on the consumer side, such as electric vehicle charging, batteries, and space heating, to larger-scale flexibility options, including battery storage systems, EV charging stations, and hydropower. Additionally, I study how the flexible potential can be quantified in both long-term and short-term perspectives, so we know what value they possess here-and-now and for future use.

In addition, a significant amount of analysis and research is conducted on the types of flexibility services that can be provided, the benefits flexibility can bring under local conditions, and how its potential should be quantified. Examples include participation in day-ahead electricity markets and reserve markets, while local grid conditions without established flexibility markets are also studied. Understanding the potential contribution of flexibility across these different needs is essential for determining how the power system should be designed, how flexible resources can be integrated, and how they should be utilized in the future.

The work is largely based on studies carried out with master's students through their master thesis projects, research projects conducted in collaboration with colleagues, and cooperation with SINTEF Energy Research.
