Research on system planning methods for large-scale grid connection of photovoltaics

With technological advancements, the extent of distributed photovoltaic grid connections has expanded. Optimizing the integration capacity of photovoltaic sources into the grid is key to reducing network loss and voltage deviations in power systems. This study first examines the effects of photovoltaic grid connections on these parameters, then it introduces a calculation method for grid integration capacity using the particle swarm optimization algorithm. The performance of this method, compared against two other algorithms, is validated through simulations in an IEEE33 node system.
