Virtual power plant configuration method and system

The invention relates to the technical field of power grid configuration, in particular to a virtual power plant configuration method and system, and the method comprises the steps: constructing an aggregation optimization model of an initial virtual power plant according to the type information and capacity information of a generator set of the initial virtual power plant; constructing a target function based on the electricity selling income, the environment penalty cost, the wind and light abandoning cost, the lease cost, the operation and maintenance cost and the risk measurement data of the initial virtual power plant; solving the objective function of the aggregation optimization model by adopting a Lagrange relaxation method based on a preset precision value to obtain a solving result meeting the preset precision value; performing aggregation optimization on the type information and the capacity information based on the solving result to obtain optimized type information and optimized capacity informat
