Transient stability-constrained maximum allowable transfer

A method is proposed for allocating generation so as to maximize power tran sfer between areas of interconnected systems under transient stability cons traints. This "transient stability-constrained maximum allowable transfer" (for short MAT) method consists of screening a large number of contingencie s, scrutinizing the dangerous ones and suggesting generation rescheduling p atterns to stabilize them. The MAT method is based on SIME, a hybrid transi ent stability method. Like SIME, MAT is accurate and free from simplifying assumptions about modelling, stability scenarios and instability modes. In addition, by controlling all dangerous contingencies simultaneously, the me thod succeeds in being fully compatible with requirements for real-time pre ventive monitoring and control. The method is illustrated on the South-Sout heast Brazilian power system, operating under highly stressed conditions im posed by large power transfer between areas.
