Virtual power plant grading settlement method and system considering contribution degree, and storage medium

Abstract

The invention discloses a virtual power plant grading settlement method and system considering contribution degree, and a storage medium. The method comprises the following steps: establishing a virtual power plant hierarchical settlement framework, the virtual power plant hierarchical settlement framework comprising a settlement framework of a virtual power plant and a power grid company and a settlement framework of aggregation resources in the virtual power plant; establishing a virtual power plant settlement basis, wherein the virtual power plant settlement basis comprises a settlement basis of a distributed power supply and a settlement basis of an adjustable load; acquiring a virtual power plant settlement contribution degree according to a virtual power plant settlement basis; and under the virtual power plant grading settlement framework, performing grading settlement in combination with the virtual power plant settlement contribution degree so as to obtain a settlement result of a power grid company on the virtual power plant and a settlement result of the virtual power plant on an internal distributed power supply and an adjustable load under a peak regulation scene. According to the invention, the grading settlement of the virtual power plant is carried out by considering the contribution degree of the internal resources, effective interaction of the virtual power plant is enhanced, integrated utilization of the internal resources is realized, and the resource utilization rate of the virtual power plant is improved.

Description

technical field [0001] The invention belongs to the technical field of power market dispatching transactions, and in particular relates to a virtual power plant hierarchical settlement method, system and storage medium considering contribution degree. Background technique [0002] Under the "dual carbon" goal, the proportion of new energy in the power system continues to increase, and it is required to fully tap the system's adjustment capacity in response to the volatility and unpredictability of new energy. At the same time, with the vigorous development of information technology, the power grid is upgraded to the Energy Internet, and a large number of low-capacity distributed energy sources are widely connected in the Energy Internet, which brings great challenges to the safe operation of the power grid. [0003] The virtual power plant is used to realize the aggregation and coordination optimization of DER such as DG, energy storage system, controllable load, electric ve...

Problems solved by technology

However, virtual power plants can participate in the medium and long-term power market, spot market, ancillary service market, and demand response market as a whole externally, and internally consider the physical and economic characteristics of internal resources such as distributed power sources, energy storage, and adjustable loads. Optimize and coordinate its power generation and consumption curves, and distribute and transmit benefits based on value contributions. At present, there are few studies on the whole process system of virtual power plant settlement and the settlement profit distribution method of virtual power plants.

[0005] Therefore, when virtual power plants are profitable, how to design a business model to realize the profit space involves how to participate in the market "externally" and how to attract and aggregate flexible resources "internally". At present, there is no mature and effective settlement plan for virtual power plants.
