摘要

In order to evaluate the safe and stable operation of distribution network with the distributed photovoltaic (PV), the?security 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.
