Abstract

The invention provides a multi-type resource optimization combination method and system for a virtual power plant. The method comprises the following steps: constructing an interaction framework of multi-party subjects in the operation of the virtual power plant; constructing a resource adjustment characteristic model of the virtual power plant interactive resources, and establishing a resource optimization combination model of the virtual power plant considering power distribution network congestion management; performing branch power flow constraint linearization, introducing a sensitivity parameter, and linearly describing a relationship between branch transmission power change and virtual power plant regulation power; and according to regulation and control authority of the virtual power plant to resources, determining a combination mode of directly controlling resources by the virtual power plant according to the resource optimization combination model, and then determining a combination mode of the resources controlled by the distributed energy users. The congestion management service is provided for the power distribution network, and the distributed energy heterogeneity canbe overcome.

Description

technical field [0001] The present invention relates to the technical field of distribution network operation, and more specifically, to a method and system for optimal combination of multiple types of resources in a virtual power plant. Background technique [0002] With the increasing proportion of energy storage, renewable energy and controllable load in the distribution network, using these scattered and flexible resources to provide services for the power grid and fully utilizing the regulation potential of these resources has become an important direction for the current smart grid construction . In this patent, these resources that can be interacted and managed distributed on the user side are collectively referred to as distributed energy resources. These distributed energy resources have large differences in all subjects, interaction willingness, and technical characteristics. Great difficulty. At present, the management of distributed energy mainly relies on acti...
