Coordination of Spatially Distributed Electric Vehicle Charging for Voltage Rise and Voltage Unbalance Mitigation in Networks with Solar Penetration
2021 IEEE Texas Power and Energy Conference, TPEC 2021
This paper proposes a decentralised control strategy using droop-based control to generate a charging schedule for electric vehicles (EV). This strategy aims to mitigate voltage rise caused by rooftop photovoltaic (PV) systems and phase unbalance caused by unbalance loads in a low-voltage distribution (LV) network. The strategy also smooths the voltage profile of the network and reduces variation between the maximum and minimum voltages. A modified IEEE 13 node test feeder with an LV network based on a semi-rural Australian town was used to show the impacts of PV and EV charging in the network and verify the proposed strategy.
