Abstract: Provided is a two-stage self-organizing optimized aggregation method and system for distributed resources of a virtual power plant. First-stage aggregation oriented to a distribution transformer area is completed by taking a natural physical cluster composed of distributed energy resources in the distribution transformer area as a first stage, performing aggregation by using an edge computing server deployed in the distribution transformer area, constructing a generalized transformer area load model including wind power, photovoltaic power, and a load, aggregating distributed gas turbines and generators of small hydropower stations in the distribution transformer area into a unified virtual synchronous generator model, aggregating distributed energy storage devices in the distribution transformer area into a centralized virtual energy storage model; second-stage aggregation across distribution transformer areas is completed by uploading all parameters of the generalized transformer area load model, the virtual synchronous generator model, and the virtual energy storage model to a cloud end.
