Centralized control of energy storages for voltage support in low-voltage distribution grids [PDF]

open access: yes2016 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.

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.
