The invention provides an analysis method of an access position in grid connection of a photovoltaic power station. The analysis method comprises the steps of: A, acquiring a plurality of influencingfactors of distributed photovoltaic feeder grid connection, wherein the plurality of influencing factors comprise a feeder structure, a line model, a power supply range, load distribution, load magnitude, photovoltaic access capacity, photovoltaic access position, photovoltaic actual output simultaneous rate and photovoltaic dynamic reactive power compensation; B, setting at least one typical value for each of the influencing factors; C, combining the typical values of the plurality of influencing factors to obtain a plurality of scenes; D, and simulating each scene, and analyzing a fluctuation percentage of voltages at the head and tail ends of a feeder to obtain an optimal scene, wherein the photovoltaic access position in the optimal scene is the optimal position of distributed photovoltaic feeder grid connection. The analysis method of the access position in grid connection of the photovoltaic power station provided by the invention can obtain the optimal position of distributed photovoltaic feeder grid connection.
