A rational substation layout can optimize grid structure, reduce power losses, and enhance grid operational efficiency. By constructing new substations or upgrading existing facilities, more balanced power distribution can be achieved, improving overall grid reliability and safety.

development and utilization of renewable energy sources are increasing, but power generation from these sources is intermittent and unpredictable. The construction and retrofitting of substations facilitate better integration of these distributed power sources, enabling

effective grid connection of clean energy.
