Power monitoring system for microgrid group

Abstract

The embodiment of the invention discloses a power monitoring system for a microgrid group. A monitoring object of the power monitoring system is the microgrid group, the power monitoring system can perform power monitoring for a plurality of microgrids in the microgrid group through one monitoring master station and a plurality of in-situ monitoring substations, meanwhile, the monitoring master station can perform information interaction with an external system, receive an active power regulation strategy / reactive power regulation strategy and issue the regulation strategy to the in-situ monitoring substations corresponding to the specific microgrid, the in-situ monitoring substations control corresponding devices in the microgrid, and thus, requirements on basic functions, such as energymanagement, coordination control, protection and communication, of the microgrids and the microgrid group can be satisfied.

Description

technical field [0001] The invention relates to the technical field of microgrid group monitoring, in particular to a power monitoring system for a microgrid group. Background technique [0002] Energy is the basis for the survival and development of human beings, while traditional coal, oil and other primary energy sources are non-renewable. Efficiency, development of new energy, and strengthening the use of renewable energy have become inevitable choices. [0003] As an autonomous system that can realize self-control and management, the microgrid can effectively absorb the output of intermittent and distributed renewable energy generation while improving the reliability of power supply for users. [0004] The micro-grid group has a wide range of application prospects. It can be used not only in land power supply systems, but also in island or archipelago power supply systems far away from the mainland. It can comprehensively utilize new energy sources such as solar energy...

AI Technical Summary

Problems solved by technology

With the development of microgrid groups, using local monitoring methods for individual microgrids to monitor the operation of microgrids, or to monitor the output of distributed power sources, is not enough to meet the needs of energy management and coordination of microgrids and microgrid groups. The requirements of basic functions such as control, protection and communication, so it is necessary to propose a power monitoring system for microgrid groups
