Quantifying Hosting Capacity for Rooftop PV System in LV Distribution Grids [article]

Jingyi Yuan, Yang Weng, Chin-Woo Tan
2019 arXiv   pre-print
Power systems face increasing challenges on reliable operations due to the widespread distributed generators (DGs), e.g., rooftop PV system in the low voltage (LV) distribution grids.  ...  Characterizing the hosting capacity (HC) is vital for assessing the total amount of distributed generations that a grid can hold before upgrading.  ...  However, for a small system such as a 3-bus system, hosting capacity can give geometrical results and intuition, shown in Fig. 2 .  ...
