Abstract

Abstract: With a large amount of distributed generators with various types integrated into the the distribution network, the microgrid is then formulated which has greatly changed the traditional protection configuration of distribution network. Considering its ownstructure of microgrids and the impacts of microgrid on distribution network protection, in this paper, the theory of Multi-Agent system is introduced to the microgrid protection design, in which the microgrid is divided into several subareas, and the faulty region can be locked by obtaining the impedance element and the directional element of power variation within each subarea. Moreover, the distributed processing and cooperation of each Agent is used to implement microgrid protection. Compared with the traditional segment protection, this design is more flexible and reliable in the aspects of relay coordination and overall performance.

Key words: microgrid, regional protection, Multi-Agent system, directional element of power variation
