Abstract

The integration of photovoltaic power into the distribution networks changes the power flow characteristics of the original distribution network and may even produce reverse power flow

drastically influencing the network loss of the distribution networks.In order to maximize the optimal configuration method when the distributed PV is connected to power grid

the loss of the distribution network is reduced to the lowest level to promote the development of green and low-carbon energy.The specific mathematical expression of the change in network loss after the integration of PV into distribution network is deduced

and the influence of typical factors such as the integration location and capacity of PV on the network loss of the distribution network is analyzed.A genetic algorithm model that comprehensively considers various influencing factors and grid constraints is proposed

which minimizes the network loss of the distribution network when PV is connected to the grid

and optimizes the PV configuration.The example simulation proves the correctness of the influence law of photovoltaic power access on distribution network loss under the influence of different factors.The optimal configuration of photovoltaic power not only enhances the operational flexibility and stability of the power grid

but also reduces network loss and improves the utilization rate of clean energy.
