Embodiment Construction

[0055] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] Based on the concept of distributed power supply matching degree, the present invention establishes a distributed power supply combination optimization model. In the virtual power plant planning and scheduling period, the model aims to minimize the matching variance of distributed power generation, satisfy certain constraints, and obtain the optimal combination scheme from the combination of distributed power generation of different types and capacities. The matching degree defined by the method of the present invention is the output matching degree of the distributed power supply, that is, the matching degree between the predicted curve of the distributed power supply and the actual output curve.

[0057] Combined with the concept of variance in mathematics, the method of the present invention proposes the c...

Abstract

The invention discloses a combination optimization method and model of a virtual power plant considering the fluctuation of distributed power sources, which includes comprehensively considering multiple factors such as geographical location, environmental conditions, and resource distribution in different regions to rationally select distributed power sources, and for each Predict the output of distributed power sources; calculate the matching degree between the predicted output of each distributed power source and the power generation and consumption plan of the virtual power plant according to the matching degree calculation formula; incorporate each distributed power source when the minimum matching degree is obtained into the virtual power plant; judge Whether the virtual power plant formed by distributed power meets the dispatching needs of the system; form a virtual power plant. The invention adopts a multi-stage nonlinear integer programming method to establish a combination optimization model of a virtual power plant in an uncertain situation. The model takes the operating state of distributed resources as a decision variable, and aims at minimizing the matching degree. Govern virtual power plant portfolio decisions.

Description

technical field [0001] The invention relates to a power system optimization method, in particular to a combined optimization method and model of a virtual power plant considering the fluctuation of distributed power sources. Background technique [0002] In recent years, virtual power plant, as a new form of distributed power generation development, has attracted more and more attention from the academic circles. The virtual power plant under the background of the smart grid has been expanded and extended. It can be understood that the distributed power supply, controllable load and energy storage system in the distribution network are combined as a special power plant to participate in the grid operation through the distributed power management system. In this way, the contradiction between smart grid and distributed power can be well coordinated, and the value and benefits brought by distributed energy to the power grid and users can be fully explored; unlike microgrids, v...
