Impact Analysis of Distributed Photovoltaic Access to Active Distribution Network with Different Permeability

This paper establishes a simulation model for the impact of the development of high-proportion distributed photovoltaic power on the distribution network, and studies the impact of distributed power on the power quality, electrical equipment and economic operation of the distribution network under various scenarios such as different access locations and different penetration rates. It is concluded that the harmonic voltage distortion rate of load nodes also monotonically increases with the increase of photovoltaic capacity, which provides a scientific basis for the collaborative planning technology of distribution network.
