Decentralized Energy Management Concept for Urban Charging Hubs with Multiple V2G Aggregators
Gümrükcü, Erdem; Klemets, Jonatan Ralf Axel; Suul, Jon Are Wold; Ponci, Ferdinanda; Monti, Antonello (Peer reviewed; Journal article, 2022)This work introduces a decentralized management concept for the urban charging hubs (UCHs) where electric vehicles (EVs) can access multiple charger clusters, each controlled by an aggregator. The given day ahead schedules ... -
A distributed algorithm for controlling continuous and discrete variables in a radial distribution grid
Klemets, Jonatan Ralf Axel; Degefa, Merkebu Zenebe (Peer reviewed; Journal article, 2023)The increased integration of distributed energy resources (DERs) in the distribution network with intermitent generation profiles will likely make voltage regulation a difficult task. However, DERs bring both challenges ... -
MPC-based Voltage Control with Reactive Power from High-Power Charging Stations for EVs
Klemets, Jonatan Ralf Axel; Torsæter, Bendik Nybakk (Chapter; Peer reviewed, 2021)The recent development of EVs with high-capacity batteries and high charging power capabilities leads to an increased demand for fast-charging stations (FCS). However, FCS can cause power quality issues such as voltage ... -

Perumalla, Chandrasekhar; Degefa, Merkebu Zenebe; Klemets, Jonatan Ralf Axel (Research report, 2021) -
Review of Grid Interconnection Requirements and Synchronization Controllers for Dispersed Minigrids
Degefa, Merkebu Zenebe; Klemets, Jonatan Ralf Axel; D'Arco, Salvatore; Sekhar, P.C.; Gupta, Amit (Chapter; Peer reviewed, 2021)As of 2019, the world population without electricity access is estimated to 770 million with most of these communities residing in sub-Saharan Africa. Nevertheless, between 2000 and 2019 the Indian population with electricity ... -
Synchronization Controller for Seamless Interconnection of Mirogrids with Heterogeneous Sources
Gupta, Amit; Sekhar, P.C.; Degefa, Merkebu Zenebe; Klemets, Jonatan Ralf Axel; D'Arco, Salvatore (Chapter; Peer reviewed, 2023)Microgrids are becoming inevitable establishments in modern power systems, may be to address energy needs in remote locations or to improve resiliency or for any other reason in the smart grid scenario. Over the time, ... -
The value of multiple data sources in machine learning models for power system event prediction
Hoffmann, Volker; Klemets, Jonatan Ralf Axel; Torsæter, Bendik Nybakk; Rosenlund, Gjert Hovland; Andresen, Christian Andre (Chapter; Peer reviewed, 2021)We describe a method for assessing the value of additional data sources used in the prediction of unwanted events (voltage dips, earth faults) in the power system. Using this method, machine learning models for event ...
