BATTPOWER application: Large-scale integration of EVs in an active distribution grid – A Norwegian case study
Zaferanlouei, Salman; Lakshmanan, Venkatachalam; Bjarghov, Sigurd; Farahmand, Hossein; Korpås, Magnus (Journal article, 2022)With the considerable increase of Distributed Energy Resources (DER), reliable and cost-effective operation of distribution grids becomes challenging. The efficient operation relies on computationally dependable and tractable ... -
Centralised and Distributed Optimization for Aggregated Flexibility Services Provision
Olivella-Rosell, Pol; Rullan, Francesc; Lloret-Gallego, Pau; Prieto-Araujo, Eduardo; Ferrer-San-José, Ricard; Barja-Martinez, Sara; Bjarghov, Sigurd; Lakshmanan, Venkatachalam; Hentunen, Ari; Forsström, Juha; Ottesen, Stig Ødegaard; Villafafila-Robles, Roberto; Sumper, Andreas (Peer reviewed; Journal article, 2020)The recent deployment of distributed battery units in prosumer premises offer new opportunities for providing aggregated flexibility services to both distribution system operators and balance responsible parties. The ... -
Charging flexibility from electric vehicles via autonomous chargers in a workplace
Skogland, Teis Kloster (Master thesis, 2021)As a part of the ongoing project Autonomously Controlled Distributed Chargers (ACDC), This thesis have designed an autonomous charging controller, with a distributed control architecture incorporating virtual aggregator ... -
Flexibility of controllable power transformers for managing wind uncertainty using robust adjustable linearised optimal power flow
Nikoobakht, Ahmad; Aghaei, Jamshid; Farahmand, Hossein; Lakshmanan, Venkatachalam; Korpås, Magnus (Journal article, 2019)As renewable energy sources (RESs) penetration increases in the power system, the transmission system operators face new challenges to ensure system reliability and flexibility while ensuring high utilisation of uncertain ... -
Generating scenarios from probabilistic short-term load forecasts via non-linear Bayesian regression
Löschenbrand, Markus; Gros, Sebastien; Lakshmanan, Venkatachalam (Chapter, 2021)In this paper we present a simple and intuitive method for fitting a non-linear Bayesian regression model on short-term load forecasts. Such models have been implemented via Bayesian neural networks, which are known for ... -
Heavy-duty electric vehicle charging profile generation method for grid impact analysis
Fjær, Kyrre Kirkbakk; Lakshmanan, Venkatachalam; Torsæter, Bendik Nybakk; Korpås, Magnus (Chapter, 2021)The transport sector is responsible for 20 % of the global CO 2 emissions. By transitioning from internal-combustion engine to battery-electric vehicles, there is a big potential in reducing the emissions. The upcoming ... -
Low-complexity Risk-averse MPC for EMS
Maree, Johannes Philippus; Gros, Sebastien; Lakshmanan, Venkatachalam (Chapter, 2021)A data-driven stochastic MPC strategy is presented as an EMS for the Skagerak Energilab microgrid. Uncertainties, introduced due to the intermittent nature of RES and load demands, are systematically incorporated into the ... -
Multimarket Services for Stationary Batteries - Considering Activation of Frequency Containment Normal Operation Reserves
Olsen, Ingvild Eline (Master thesis, 2023)Kraftsystemet er i endring; fra et sentralisert system til et desentralisert system [1]. Endringen drives av behovet for å begrense klimaendringer og imøtekomme samfunnets økende behov for elektrisitet. Som følge av dette ... -
Simplified Battery operation and Control algorithm
Ottesen, Stig Ødegaard; Olivella, Pol; Lloret, Pau; Hentunen, Ari; Del Granado, Pedro Crespo; Bjarghov, Sigurd; Lakshmanan, Venkatachalam; Aghaei, Jamshid; Korpås, Magnus; Farahmand, Hossein (Research report, 2017)
