Technical FAQs 4

Why is photovoltaic hosting capacity important in low-voltage distribution systems (LVDS)?

Photovoltaic (PV) in low-voltage distribution systems (LVDS) becomes problematic when the penetration level exceeds system photovoltaic hosting capacity (PVHC), since it leads to violations of power quality constraints. Maximizing PVHC enables customer service expansion by allowing more power from prosumers and load attendance.

What are the operational limitations of a solar PV network?

Any DN can face operational limitations if the solar PV penetration exceeds the rated infeed level, known as the HC of the network, and can jeopardize the safety and reliable operation of the grid .

Can a voltage control strategy improve low voltage distribution grid performance?

This study presents a novel voltage control strategy for low voltage (LV) distribution grids, addressing the lack of coordination between photovoltaic (PV) reactive control and energy storage system (ESS) active control. The proposed strategy concentrates on group coordination of PV and ESS to improve LV grid performance.

What is PV hosting capacity (pvhc)?

This maximum level of PV generation that can be accommodated in a distribution system is the PV hosting capacity (PVHC) (Xu et al., 2019; Mulenga et al., 2020).
