Voltage control challenges and potential solutions for large-scale integration of PV resources in LV networks

In this paper we illustrate PV single inverter response to voltage rise in LV networks and simulate multiple PV cascading that may result from inverter´s response. We then address potential solutions to mitigate the drawbacks of simplistic control approaches, such as reinforcing the network, shifting supply phases, and implementing enhanced control processes. We elaborate on the framework of such control processes and identify main implementation challenges to make them effective.
