Virtual power plant model for common operation of commercial and technical virtual power plants

Abstract

The invention relates to a virtual power plant model for common operation of commercial and technical virtual power plants. A virtual power plant operation model is established according to differentfunctions of different models needed to be determined and divided for operation in the virtual power plant; the operation of the virtual power plant is completed through regulating specific functionsof the commercial virtual power plant and the technical virtual power plant; inner optimization and unified scheduling are carried out on the basis of the variety and uncertainty of distributed energyresources; finally, electric energy interaction with an external power grid is realized according to requirements; inner loads are met and certain economic benefits are realized. Aiming at the problems that an existing virtual power plant model is relatively complicated and inner operation cannot be clearly known, the virtual power plant operation model provided by the invention can be used for conveniently and clearly analyzing functions of all modules in the virtual power plant operation model, and an operation manner of information flows and power flows in the virtual power plant is known;method guidance is provided for resource storage optimal allocation of the virtual power plant and operation optimization of the virtual power plant.

Description

technical field [0001] The invention relates to a distributed energy operation technology, in particular to a virtual power plant model in which a commercial virtual power plant and a technical virtual power plant operate together. Background technique [0002] In modern power applications, the application of distributed energy is more and more extensive. When a large number of distributed power sources are connected to the traditional power grid, the input and output power of the power grid will not match, resulting in serious fluctuations in frequency and voltage amplitude, threatening the stable operation of the power grid, and greatly limiting the application of distributed energy in modern power systems. . Virtual power plant is an effective way to solve the grid-connected use of distributed energy, but the operation of the existing virtual power plant model is relatively complicated, and it is difficult to determine the specific operation mode of each module in the vi...
