ABSTRACT: In order to evaluate the safe and stable
operation of distribution network with the distributed photovoltaic (PV), thesecurity
of distribution network is researched. On the basis of electricity
supply security, voltage quality and network losses,the index system of static security is established. The paper
simulates the uncertainty and random characteristics of PV by OpenDSS. The
typical scenes that PV accessed to the
distribution network are designed.The paper
summarizes the results of voltage fluctuation and network losses and uses
indices to quantify it under different scenes. Based on the index system, the
paper proposes some recommendations on PV permeability,
interconnected locations, dispersion degrees and power factors when the
distributed PV accessed to the distribution network.
