| Abstract: | Large-scale grid-connected solar generation system plays an important role in the development of new energy sources. This paper analysis the characteristics of large-scale photovoltaic power generation system. The main impacts on the power grid with large-scale PV integration are elaborated. In addition, this paper also reviews the dynamic and static models for better stability studies. The influence of the harmonic and voltage quality on the power quality is analyzed, the overvoltage/overcurrent problems under unbalanced grid faults, low voltage ride through (LVRT) technology and islanding detection technology are also presented. Besides, the corresponding solutions and countermeasures are summarizes. Offering references for readers from the perspective of power system planning, simulation, and control strategy. |
