A method for mapping microgrid multi-agent control to IEC61850-goose

Abstract

The invention discloses a method for mapping micro-grid multi-agent control to IEC61850-GOOSE, which includes two parts: a data model mapping part and a communication service mapping part, and the data model mapping part further includes two mechanisms: Agent establishment in the micro-grid Mechanism, sub-agent information modeling mechanism based on agent communication language and IEC61850. The communication service mapping part also includes two mechanisms: the GOOSE state machine establishment mechanism based on the proxy communication language, and the GOOSE message processing flow setting mechanism. The present invention fully considers the agent characteristics in the microgrid and the characteristics of the IEC61850 information model, and the microgrid function agent and its communication rules established after mapping enable the microgrid to meet emerging new demands, which is conducive to the establishment of efficient and orderly competition and negotiation The system can interact with off-site systems and equipment in a larger range, and jointly complete the distributed interactive function of the microgrid.

Description

technical field [0001] The invention belongs to the technical field of micro-grids, and relates to a method for mapping multi-agent control in a micro-grid to IEC61850-GOOSE. Background technique [0002] With the development of distributed power generation technology, the traditional centralized intelligent control method has been difficult to adapt to the rapid growth of distributed power generation due to lack of flexibility and scalability. Microgrid is a new type of power grid that combines distributed power sources, energy storage devices, controllable loads and other units. , Switch between two transient operation modes from island to network mode. Massive control data, distributed characteristics and changeable control methods in microgrid increase the difficulty of its scheduling. [0003] The multi-agent system (Multi-agentSystem, MAS) has good centralized-decentralized characteristics, and has attracted attention in many fields such as microgrid management and c...

AI Technical Summary

Problems solved by technology

At present, the research on the application of MAS in microgrid has achieved many results, but most of the studies only proposed the framework of microgrid based on MAS, and did not involve the specific agent negotiation process, and the communication mechanism and communication language between agents are relatively Vague

[0005] In addition, there are significant differences between the equipment of different manufacturers in the microgrid, and there is no unified specification for the content, organization and interaction methods of communication information.
