Abstract EN
Distributed rooftop photovoltaic (PV) generators prospered distributed generation (DG) in recent years.
Certain randomness of rooftop PV connection may lead to significant PV power imbalance across three phases, especially in low-voltage distribution systems.
Due to interphase line coupling, traditional Var compensation methods which typically have competent voltage regulation performance may become less effective in such PV imbalance scenarios.
In this paper, the limitation of traditional Var compensation methods in voltage regulation with unbalanced PV power integration is demonstrated and comprehensively analyzed.
After describing the voltage regulation challenge, based on the voltage sensitivity analysis, it is revealed that PV power unbalanced level together with equivalent mutual impedance among phase conductors has a significant impact on the effectiveness of traditional Var compensation methods on voltage regulation.
On this basis, to improve the performance of voltage regulation methods, some suggestions are proposed for both current system operation and future distribution system planning.
Numerical studies demonstrate the effectiveness of the proposed suggestions.
Future rooftop PV integration in LV systems can benefit from this research.
