AI Customer ServiceVoltage control is one of the urgent issues in distribution systems for solar PV integration. Many LV networks have been designed decades ago, and are not well prepared to accommodate the large amount of power flowing through the grid. This paper describes the mechanism of the voltage rise issue, and the possible mitigation solutions.
The PV systems and EVs act as supplementary voltage regulation resources. The PV systems are always grid-connected, and their voltage regulation capability is achieved using the device-level reactive power control, with the control range mainly determined by the operating power level (and hence the solar irradiation level).
In terms of research on PV participation in distribution voltage regulation, refs. [ 13, 14] dynamically adjust the voltage at the grid connection point based on PV inverters’ reactive power compensation capability.
In distributed voltage control, the distribution network with EVs and PVs connected is first partitioned into several regions based on the similarity of bus voltage sensitivity. Then, regional voltage control is applied to each regional distribution network via the active and reactive power control of their member EVs and PVs [ 34, 35 ].
To further enhance the voltage support capability of EV chargers and PV inverters in future studies, a mild decoupling between fully controllable PE converters and the power grid is required, which can be achieved by adequately designed battery energy storage systems integrated into EV charging stations and PV parks.
The direct integration of a PV system with an EV charging station (EVCS) as the solar PV-based EVCS is a possible way to accommodate more clean energy and alleviate peak charging load [ 27 ]. Ref. [ 28] proposes a distributed control strategy for solar PV-based EVCS to achieve optimal power allocation within the EVCS.
