Abstract

The invention provides a method and system for optimizing multi-type resources of a virtual power plant, including constructing an interaction framework of multiple parties in the operation of the virtual power plant; Resource optimization combination model; branch power flow constraints are linearized, and sensitivity parameters are introduced to linearly describe the relationship between branch transmission power changes and virtual power plant regulation power; according to the control authority of virtual power plants to resources, first determine according to the resource optimization combination model The combination of resources is directly controlled by the virtual power plant, and then the combination of resources controlled by distributed energy users is determined. The above resource optimization combination method and system provide congestion management services to the distribution network and can overcome the heterogeneity of distributed energy resources.

Description

technical field [0001] The invention relates to the technical field of distribution network operation, and more particularly, to a method and system for optimizing and combining multiple types of resources in a virtual power plant. Background technique [0002] As the proportion of energy storage, renewable energy, and controllable loads in the distribution network continues to increase, using these decentralized and flexible resources to provide services to the power grid and giving full play to the regulation potential of these resources has become an important direction for the current smart grid construction . In this patent, these resources distributed on the user side that can be interacted and managed are collectively referred to as distributed energy resources. These distributed energy resources are quite different in terms of all subjects, interaction willingness, and technical characteristics, and the power grid directly manages them. Great difficulty. At present...
