The invention discloses a power distribution network and virtual power plant power-carbon cooperative scheduling method based on multistage gradient descent. The method comprises the steps of obtaining a power distribution network and virtual power plant power-carbon cooperative scheduling double-layer optimization model; the lower-layer model is converted into a first unconstrained optimization problem, a first-level gradient is calculated, and then an initial decision of the virtual power plant is calculated; constructing a single-valued mapping problem of a multi-virtual power plant, and converting the single-valued mapping problem into a second unconstrained optimization problem; according to a second unconstrained optimization problem, calculating a second-level gradient and an optimal decision of all virtual power plants; converting the upper-layer model into a third unconstrained optimization problem, calculating a third-level gradient, and then calculating an optimal decision of the power distribution
