Problems solved by technology

As the main force of clean energy, wind power photovoltaic has the characteristics of uncertain power generation output, which brings new challenges to transmission network planning
[0004] The inventors of the present disclosure found that the existing modeling method for transmission network planning needs to enumerate a huge number of envisioned scenarios to ensure the reliability of system operation, but this will make the optimization model too large and difficult to solve; Some equipment is overloaded for a long time, which reduces the service life of the equipment and greatly increases the maintenance cost
