The Voltage Fluctuation Characteristic Analysis Of Regional Power Network With High-Penetration Pv System

Distributed photovoltaic system as an important new energy access to low voltage power distribution network, due to the fast random variety of photovoltaic system output, the voltage fluctuation at the point of common coupling is becoming increasingly prominent. Firstly, the voltage fluctuation characteristic of regional power network with high-penetration photovoltaic system is analyzed using mathematical method. Secondly, a model of typical low voltage power distribution network with photovoltaic system is introduced. Finally, the voltage fluctuations of regional power network with different penetration photovoltaic system are simulation analysis.
