Agent-Based Analysis of Spatial Flexibility in EV Charging Demand at Public Fast Charging Stations
(Chapter; Peer reviewed, 2021)Electric Vehicles (EV) have been increasingly investigated in the recent years as a potential tool for improving the flexibility of power systems. Nevertheless, this research area still lacks of modelling approaches that ... -
Aggregation model for curtailable generation and sheddable loads
(CIRED Conference Proceedings;2017, Chapter; Peer reviewed, 2017)This paper shows modelling developed during the first year of the SmartNet project. In particular, it presents a mathematical model for aggregation of curtailable gener-ation and sheddable loads. The model determines the ... -
Air Flow Measurements During Medium-Voltage Load Current Interruptions
(Journal article; Peer reviewed, 2015)Air has been considered a good alternative to SF6 as arc quenching medium for load break switchgear at medium voltage ratings. In this work, the air flow characteristics and influence from the electric arc have been studied ... -
Air heating of passive houses in cold climates: Investigation using detailed dynamic simulations
(Journal article; Peer reviewed, 2014)The passive house (PH) standard was originally defined for Central Europe and has subsequently been applied to many cold climate countries. In these conditions, the relation between this standard and the air heating (AH) ... -
