Object-oriented Knowledge Representation for Stability Limit of Power Grid

At present, the application of stability limit of transmission interface mainly relies on manual input control platform and data maintenance, and intelligent identification and expression has not been realized yet. This paper proposes an object-oriented artificial intelligence identification and knowledge representation for stability limit of power grid. First, classify and decompose the stability limit. Combining with object-oriented knowledge structure, establish the model of stable quota without monitoring condition and with monitoring condition under normal and maintenance mode. Finally, the method is used to instantiate knowledge expression of various stability limits.
