Distributed energy resource information modeling and information interacting method

Abstract

The invention discloses a distributed energy resource information modeling and information interacting method. Firstly, abstract analysis is conducted on distributed energy resources, and abstract class domains of the distributed energy resources are determined; secondly, concrete analysis is conducted on equipment of the distributed energy resources and other resources, and properties and property value types of abstract classes of the distributed energy resources are extracted; then, differentiation analysis is conducted on the abstract classes and the properties of the distributed energy resources and electric system public information models made according to the IEC61970/61968 series standard, the abstract classes needing domain expansion and the properties needing private expansion are determined, and as for the abstract classes and the properties existing in the standard, a mapping relation is built; on the basis of distributed energy resource information models built according to the information modeling method, according to the service scene requirement for intelligent power grid management and monitoring, messages of the distributed energy resources are designed for information interaction based on information integration buses. The distributed energy resource information modeling and information interacting method solves the technical problem of uniform information modeling of the distributed energy resources in the intelligent power grid context and the problem of information interacting of the distributed energy resources during intelligent power grid equipment management and power gird dispatching.

Description

technical field [0001] The invention relates to a modeling method for a distributed energy public information model in the field of smart grid information integration, and a distributed energy information interaction method based on an electric power enterprise information integration bus of the IEC61970 / 61968 standard. Background technique [0002] With the depletion of fossil fuels and the increasing environmental problems, the importance of distributed clean energy is gradually escalating. The rapid development of smart grids puts forward new requirements for the information integration of distributed energy sources. The information of distributed units such as photovoltaics, fuel cells, wind power, and energy storage systems needs to be integrated. The key to information integration is that each system must have a unified information model. At present, more and more power systems adopt the object-oriented CIM model formulated by IEC61970 / 61968; while the distributed ener...

The key to information integration is that each system must have a unified information model. At present, more and more power systems adopt the object-oriented CIM model formulated by IEC61970 / 61968; while the distributed energy model is not involved in the standard CIM. In order to meet the needs of distributed energy information integration, it is necessary to carry out unified information modeling for distributed energy
