The Impact of High Permeability Photovoltaic Grid Connection on Voltage and Its Governance Plan

High penetration photovoltaic grid connection directly affects the power quality and operational safety of the distribution network, and is the key to voltage control in the distribution network. Starting from the high penetration characteristics of distributed photovoltaics, this article studies the fluctuation of feeder voltage in rural power grids after photovoltaic integration, the influence of grid connection capacity and connection position on feeder terminal voltage is calculated, and the inverter power factor and boost voltage level are adjusted in a targeted manner to ensure the safety and economic benefits of high penetration photovoltaic integration.
