Method for a public building virtual power plant to participate in flexible peak regulation of power grid in grading manner

Abstract

The invention discloses a method for a public building virtual power plant to participate in flexible peak regulation of a power grid in a grading manner, and the method comprises the following steps: step 1, participating in peak regulation autonomous decision, step 2, determining a response grade, and step 3, executing a response operation. According to the method, from the demand side of the public building users, the decision that the public building users autonomously and actively make participation in the flexible peak regulation of the power grid is provided, the decision basis is given, and the enthusiasm of the public building users to flexibly participate in the interaction of the power grid can be better stimulated and mobilized.

Description

technical field [0001] The invention belongs to the technical field of virtual power plants participating in smart grid dispatching, and in particular relates to a method for public building virtual power plants to participate in flexible peak regulation of power grids in stages. Background technique [0002] As renewable energy becomes the main direction of global energy development in the future, virtual power plants have become a regional multi-energy aggregation model that realizes large-scale access to the grid for renewable energy generation. The virtual power plant is proposed to integrate various distributed energy sources, including distributed power sources, controllable loads, and energy storage devices. Its basic concept is to aggregate distributed power sources, controllable loads and energy storage devices in the power grid into a virtual controllable aggregate through a distributed power management system, participate in the operation and scheduling of the pow...

[0005] Comparative document 2 (patent application number 202010096705.3) discloses an integrated energy system optimization method and system based on the participation of virtual power plants. The minimum-objective integrated energy system optimization method, and the integrated energy optimization model and objective function are given, but it does not mention the virtual power plant participating in the hierarchical structure of the integrated energy system scheduling, and its application scenarios have not been accurately reduced to public buildings Building scene

[0006] To sum up, the collection accuracy of available electricity resources in public buildings is not high, and the level of refinement of resource control in virtual power plants is insufficient. From the perspective of the power grid, a strategy for the rigid participation of public building loads in power grid dispatching is given, but there are few accurate proposals for public building users to actively participate in the flexible peak regulation of the power grid based on user-side demand
