Available transfer capability assessment in a competitive electricity market using a bifurcation approach

摘要

An application of bifurcation criteria is proposed for available transfer capability (ATC) determination in a competitive power market having bilateral as well as multilateral transactions. The Hopf bifurcation limit has been considered for determination of the dynamic ATC. The saddle node bifurcation and bus voltage limits have been used for static ATC determination. The proposed method has been applied for ATC determination on a 39-bus New England system and a 68-bus system having static loads as well as in the presence of induction motor loads. The impact of SVC placement in the system for the enhancement of ATC has also been studied.
