Double-layer optimization method and device for rural virtual power plant electricity seller system

The invention relates to a double-layer optimization method and device for a rural virtual power plant electricity seller system, belongs to the technical field of power electronics, and solves the problem of how to carry out VPP-ER double-layer optimization urgently needing to be solved in current novel power system transformation. The method comprises the following steps: establishing a plurality of unit models based on rural VPP and rural area load demands; establishing a collaborative transaction mathematical model based on electricity-carbon-green certificate collaborative transaction, wherein the collaborative transaction mathematical model comprises a green certificate transaction cost model; an upper electricity-carbon-green certificate market collaborative transaction optimization model is constructed based on a collaborative transaction mathematical model, the income and risk cost of the VPP-ER system participating in the electricity-carbon-green certificate market collaborative transaction are cons
