Impact of EV Integration and Fast Chargers in a Norwegian LV Grid - An analysis based on data from a residential grid in Steinkjer
(Master thesis, 2018)Given a renewable power supply, the replacement of conventional vehicles with electric alternatives has the potential to significantly reduce climate gas emissions from the transport sector. Norway has implemented economic ... -
Impact of Fast Charging Stations on the Reliability of Electricity Supply in Distribution Networks
(Master thesis, 2019)Innen 2050 har Norge en ambisjon om å bli et lavutslippssamfunn med nullutslipp fra transportsektoren. Dette fører til en stor økning i elektrifisert transport, og følgende et behov for lading. Dermed installeres det i dag ... -
The impact of Flow-Based Market Coupling on the Nordic region
(Peer reviewed; Journal article, 2020)The primary objective of capacity calculation is to reflect physical transmission limits in the power grid into limits on commercial trades at the electricity markets. The Nordic capacity calculation methodology is currently ... -
Impact of Grid Tariffs Design on the Zero Emission Neighborhoods Energy System Investments
(Chapter, 2019)This paper investigates the relationship between grid tariffs and investment in Zero Emission Neighborhoods (ZEN) energy system, and how the grid exchanges are affected. Different grid tariffs (energy based, time of use ... -
Impact of home- and destination charging on the geographical and temporal distribution of electric vehicle charging load
(Chapter, 2022)In this paper, we analyse how a shift from home charging to destination charging impacts the charging demand, based on data from a regional transport model and results from an EV survey. The impact and flexibility potential ... -
Impact of hydro-turbine and governor parameters on stability of grid connected power system
(Journal article; Peer reviewed, 2017)Hydro-turbine and governor parameters affect power system stability. It is essential to identify the parameters of the hydraulic system, turbine, and governor to improve the powersystem stability. In this study, we carry ... -
Impact of Industrial Size Battery Storage Systems on Electricity Price Distribution
(Master thesis, 2023)Batterilagringssystemer (BLS) har vokst frem som en lovende teknologi for å håndtere energisikkerhetsutfordringene forårsaket av de uregelmessige egenskapene til Variabel Fornybar Energi (VFE). For å undersøke effekten av ... -
Impact of inertial response requirements on a multi area renewable network
(Chapter, 2017)Developments in renewable integration are continuously changing power system portfolios globally. Higher volatility of the networks might pose a threat to grid stability and thus increase the need for ancillary services. ... -
Impact of large-scale EV integration and fast chargers in a Norwegian LV grid
(Journal article; Peer reviewed, 2019)Norway has implemented economic incentives over several years to encourage a transition from conventional vehicles to electric vehicles (EVs), and now has the largest share of EVs per capita in the world. In this study, ... -
