Embodiment Construction

[0019] The technical scheme of the invention will be described in detail below in conjunction with the drawings:

[0020] The IEC61850 standard is the world's first global standard for information model and information exchange in substation automation systems. With the gradual maturity and wide application of IEC61850 technology, its technology and methods are gradually being extended to other application fields besides substation automation. The service provided by the IEC61850 standard is mainly divided into three parts: MMS service, GOOSE service and SV service.

[0021] MMS (Manufacturing Message Specification, manufacturing message specification) is the most important specific communication service mapping in the IEC61850 standard. It is used for data interaction between smart electronic devices and the monitoring background, and can realize most of the services required by the power system monitoring function.

[0022] GOOSE (Generic Object Oriented Substation Event) service ...

Abstract

The invention discloses an IEC61850 standard-based microgrid comprehensive coordination control framework, belonging to the technical field of power system automation. The microgrid comprehensive coordination control framework comprises a micro power supply controller, a load controller, a microgrid central controller, a microgrid mode controller and a microgrid energy management system. In the framework, monitoring information having low requirement on real-time property and control information having high requirement on the real-time property in the microgrid are transmitted separately, and thus, the transmission efficiency of a microgrid is improved; a master microgrid and sub-microgrids are controlled coordinately, the load on a central controller of the master microgrid is reduced, and the timeliness of the microgrid coordination control is improved.

Description

Technical field [0001] The invention discloses a microgrid comprehensive coordination control architecture based on the IEC61850 standard, which belongs to the technical field of power system automation. Background technique [0002] Microgrid refers to a small power generation and distribution system that is composed of DER (Distributed Energy Resource), energy storage devices, energy conversion devices, related loads, monitoring, and protection devices. It is a small power distribution system that can realize self-control, protection and The managed autonomous system can operate in conjunction with the large power grid or in isolation. The microgrid needs to transition as smoothly as possible in the process of switching between different operating modes, and its control process is very complicated. If you want to achieve seamless switching between different operating modes, its control response speed requires higher. [0003] In large power grids, frequency can be maintained by...
