Abstract
This paper presents a comprehensive approach for dynamically estimating the hosting capacity of photovoltaic (PV) systems. The proposed method takes into account time-dependent fluctuations of generation and load, as well as overvoltage constraints, in its mathematical model. A set of weekly measurements taken every minute from a low-voltage side of a university building in Morocco were analyzed to show load variations.The proposed approach is compared to a static method to demonstrate its effectiveness. The results show that the voltage increases after PV integration, but does not cause overvoltage, even in the worst-case scenario where generation exceeds load demand. To address voltage fluctuations, the use of Static VAr Compensators (SVC) and Static Synchronous Compensators (STATCOM) in distribution systems was compared. The simulation results indicated that STATCOM was more effective than SVC in mitigating voltage fluctuations, resulting in an improvement of the PV hosting capacity.
