Alleviation of Voltage Variations Introduced by Unbalanced Allocation of Single-phase Loads in a Distribution Network Integrated with PVs and PEVs

Conference Paper


Abstract


  • Due to the economic and environmental benefits, it is envisaged that many residential customers will increasingly utilize rooftop photovoltaic (PV) systems and plug-in electric vehicles (PEVs). However, the intermittent nature of PVs and the additional loads required for the PEV charging can increase the power quality issues in the low voltage distribution networks (LVDN). In particular, the surplus PV produced power during low load and the random connection of PEVs in addition to the asymmetrical loading levels of residential consumers can aggravate the voltage quality in LVDNs. In this paper, different voltage parameters for the LVDNs with installed rooftop PVs and PEVs are assessed. Further, a novel control strategy is proposed for the domestic management of the PEV charging and the efficacious utilization of reactive power for maintaining the voltage variations within the allowable limits. The simulation results demonstrate the impacts of the integration of PVs and PEVs on the voltage quality and confirm the effectiveness of the proposed strategy to mitigate the voltage variations in LVDNs.
