Claim 5:
6. An apparatus for identifying a power feasible region of a virtual power plant of a power system, wherein the virtual power plant comprises an internal power-distribution system, and the apparatus comprises:
a memory;
a processor; and
a computer program stored on the memory and capable of running on the processor,
wherein the processor is configured to perform actions of:
S1, obtaining operation basic data of the internal power-distribution system;
S2, establishing a static safety-constrained model of the virtual power plant based on the operation basic data, in which the static safety-constrained model is based on alternating current power flow equations;
S3, establishing a power feasible region model of the virtual power plant based on the static safety-constrained model;
S4, obtaining the power feasible region of the virtual power plant by calculating the power feasible region model based on the operation basic data and a feasible region vertex enumeration algorithm, wherein the power feasible region of the virtual power plant is a bounded area within a two-dimensional space; and
dispatching the power system to adjust active and reactive power of the internal power-distribution system of the virtual power plant to clear a power spot market within the bounded area of the power feasible region.
