Claim 3:
4. The method of claim 3, wherein S3 comprises:
S31, determining a static safety-constrained feasible region of the virtual power plant based on the static safety-constrained model, in which the static safety-constrained feasible region is denoted by a formula of:

Ω={(v,θ,Pg,Qg,P0,Q0)|s.t.(1)˜(7)}  (8), where,
Ω represents the static safety-constrained feasible region;
v represents a vector with vi as elements,
θ represents a vector with θi as elements,
Pg represents a vector with Pig as elements,
Qg represents a vector with Qig as elements; and
S32, aggregating the static safety-constrained model by eliminating internal state variables v and θ, and internal decision variables Pg and Qg of the virtual power plant, into the power feasible region model, in which the power feasible region model is related to the active power output of the virtual power plant and the reactive power output of the virtual power plant, and the power feasible region model is denoted by a formula of:, Φ
