Transformer area uncertainty on-site management scheduling method based on low-voltage flexible direct current interconnection

The invention discloses a transformer area uncertainty on-site management scheduling method based on low-voltage flexible direct-current interconnection. The method comprises the following steps: establishing an on-site management strategy considering transformer area uncertainty of flexible direct-current interconnection; establishing a day-ahead optimization model with the goal of minimizing the operation and maintenance cost of the transformer area; establishing a real-time optimization model with the minimum deviation of the power purchasing power of the transformer area in the two stages as a target; and based on the day-ahead-real-time two-stage optimization model, a commercial solver is adopted to solve the model. According to the method, on-site management of the uncertainty of the new energy power generation power can be realized, the influence of intermittency and volatility on a superior power grid is reduced, and tracking of a planned power purchase power curve is realized through a two-stage opti
