An Investigation of Voltage Unbalance in Low Voltage Distribution Networks with High Levels of SSEG

Voltage imbalance analysis in residential low voltage distribution networks with rooftop PVs

“…motors for pumps and elevators). References [9][10] have investigated some technical problems of European and UK distribution networks for maximum allowable number of grid-connected PVs. However there is a need to investigate the sensitivity analysis of voltage imbalance in these networks.…”

Coordination of single-phase rooftop PVs to regulate voltage profiles of unbalanced residential feeders

“…The high number of rooftop PVs can also change the direction of power flow and lead to voltage rise along the feeder. In addition, most of the residential rooftop PV systems are singlephase units and their integrations into the three-phase networks might also cause unbalance issues due to their random locations and ratings [2][3]. These are some of the main issues and challenges that most electrical utilities are currently encountering.…”

Sensitivity analysis of voltage imbalance in distribution networks with rooftop PVs

“…Along with the increase of rooftop PV application for residential loads, which are usually distributed randomly among the customers of the network, one of the main power quality concerns is whether their random locations and ratings in the network might lead to an increase in the imbalance index of the network beyond the standard values [11]. References [11][12] have investigated the maximum allowable number of gridconnected PVs in European and UK distribution networks based on voltage imbalance standard limitations.…”

“…References [11][12] have investigated the maximum allowable number of gridconnected PVs in European and UK distribution networks based on voltage imbalance standard limitations. However the penetration of rooftop PVs will increase the maximum limits.…”
