A co-simulation framework to coordinate battery optimization and load flow - Improving voltage quality in the distribution grid
Hillestad, Runar (Master thesis, 2022)Økningen av distribuerte energi ressurser slik som solcellepanel (PV) og effektkrevende apparater har skapt nye utfordringer som leveringskvaliteten på spenningen for distribusjonsnettet, og det er kanskje mulig å bruke ... -
A data set of a Norwegian energy community
Berg, Kjersti; Löschenbrand, Markus (Peer reviewed; Journal article, 2021)This paper presents a data set designed to represent Norwegian energy communities. As such it includes household consumption data collected from smart meter measurements and divided into consumer groups, appliance consumption ... -
The impact of degradation on the investment and operation of a community battery for multiple services
Berg, Kjersti; Bjarghov, Sigurd Nikolai; Rana, Rubi; Farahmand, Hossein (Chapter, 2022)The emergence of local energy communities (LECs) introduces new concepts and dynamics to the operations of distribution grids. An important part of LECs is the shared ownership or control of assets such as photovoltaic ... -
Industrial energy communities: Energy storage investment, grid impact and cost distribution
Berg, Kjersti; Foslie, Sverre Stefanussen; Farahmand, Hossein (Journal article; Peer reviewed, 2024)Energy communities are a way for end-users to contribute to the green shift, by installing distributed energy resources such as photovoltaic panels. The focus of energy community studies has mainly been on residential and ... -
Local electricity market pricing mechanisms’ impact on welfare distribution, privacy and transparency
Dynge, Marthe Fogstad; Berg, Kjersti; Bjarghov, Sigurd Nikolai; Cali, Umit (Journal article; Peer reviewed, 2023)Local energy communities and electricity markets have emerged as possibilities for interaction among prosumers. A substantial effort has been invested into creating efficient pricing mechanisms for various market arrangements, ... -
Local energy communities: Member benefits and grid impact under various regulatory frameworks
Berg, Kjersti (Doctoral theses at NTNU;2024:231, Doctoral thesis, 2024)Due to global warming, there is a need to electrify fossil fuel processes and increase the amount of renewable energy. A way to include citizens in this green shift is by making it easier to invest in renewable technology ... -
Modelling and Simulation Approaches for Local Energy Community Integrated Distribution Networks
Rana, Rubi; Berg, Kjersti; Degefa, Merkebu Zenebe; Löschenbrand, Markus (Journal article; Peer reviewed, 2022)Due to the absence of studies of local energy communities (LECs) where the grid is represented, it is very difficult to infer implications of increased LEC integration for the distribution grid as well as for the wider ... -
Optimisation model with degradation for a battery energy storage system at an EV fast charging station
Haugen, Eirik; Berg, Kjersti; Torsæter, Bendik Nybakk; Korpås, Magnus (Chapter, 2021)The electrification of the energy sector challenges the conventional methods to meet the increased load demand. The rapid increase of electric vehicles and the desire for shorter charging time at fast charging stations ... -
Optimization of battery energy storage system: A case study for an electric vehicle fast-charging station
Haugen, Eirik (Master thesis, 2020)Stadig økende andel elbiler og ladeeffekt, samt utbygging av hurtigladestasjoner, skaper nye utfordringer, blant annet økte effekttopper og mer varierende effekt. Med økende ladeeffekt vil ladetiden gå ned, og kombinasjonen ... -
Power Flow Tracing: Methods and Algorithms - Implementation Aspects
Berg, Kjersti (Master thesis, 2017)With the advent of deregulation, power systems across the world have undergone major restructuring. The unbundling of generation, transmission and distribution services has led to the emergence of electricity markets. One ... -
Quantifying the benefits of shared battery in a DSO-energy community cooperation
Berg, Kjersti; Rana, Rubi; Farahmand, Hossein (Peer reviewed; Journal article, 2023)Local energy communities are forming as a way for prosumers and consumers to invest in distributed renewable energy sources, community storage and share electricity. Meanwhile, several distribution grids have voltage ... -
Sikker vernutkobling i elektriske installasjoner i svake lavspenningsnett
Skyrud, Nikolai Tøllefsen (Master thesis, 2021)De siste 10-15 årene har nettselskapene fått bedre verktøy til å beregne minste kortslutningsstrøm tilført til de elektriske installasjonene i lavspenningsnettet. Nettselskapene har derfor avdekket områder der minste ... -
A systematic review of machine learning techniques related to local energy communities
Hernandez-Matheus, Alejandro; Löschenbrand, Markus; Berg, Kjersti; Fuchs, Ida; Aragüés-Peñalba, Mònica; Bullich-Massagué, Eduard; Sumper, Andreas (Peer reviewed; Journal article, 2022)In recent years, digitalisation has rendered machine learning a key tool for improving processes in several sectors, as in the case of electrical power systems. Machine learning algorithms are data-driven models based on ...
