The invention discloses a double-layer energy optimization scheduling method for a multi-energy complementary system. The method comprises the following steps: acquiring a correlation coefficient matrix of each variable in a normal space based on Nataf transformation, and acquiring a sample matrix group; performing 2PEM evaluation and series expansion fitting by taking the sample matrix group as an input variable to obtain a probability density function; constructing a quadratic programming model, and solving the quadratic programming model based on an improved effective set method; a robust optimization model is constructed based on a risk avoidance strategy, and the influence of wind and light load uncertainty on an energy storage configuration result is avoided; an MPC rolling optimization model is constructed to reduce deviation; constructing a double-layer energy optimization scheduling framework based on an MPC rolling optimization model and a robust optimization model; and correcting a day-ahead schedu
