Analysis of voltage support by electric vehicles and photovoltaic in a real Danish low voltage network [PDF]
2014 49th International Universities Power Engineering Conference (UPEC), 2014 With conventional generating units being replaced by renewable sources which are not required to provide same high level of ancillary services, there is an increasing need for additional resources to achieve certain standards regarding frequency and voltage. This paper investigates the potential of incorporating electric vehicles (EVs) in a low voltage

Centralized control of energy storages for voltage support in low-voltage distribution grids [PDF]
2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC), 2016 This paper presents a centralized voltage control scheme for unbalanced low-voltage grids experiencing over voltage problems due to high PV power penetration. Voltage control is primarily achieved by remotely controlling the active power of the distributed battery energy storage systems, which are owned by the customers.
