Abstract

THIS PAPER PROPOSES A NOVEL APPROACH FOR COHERENTGENERATORS ONLINE CLUSTERING IN A LARGE POWER SYSTEM FOLLOWING AWIDE AREA DISTURBANCE. AN INTERCONNECTED POWER SYSTEM MAYBECOME UNSTABLE DUE TO SEVERE CONTINGENCY WHEN IT IS OPERATEDCLOSE TO THE STABILITY BOUNDARIES. HENCE, THE BULK POWER SYSTEMCONTROLLED ISLANDING IS THE LAST RESORT TO PREVENT CATASTROPHICCASCADING OUTAGES AND WIDE AREA BLACKOUT. MEANWHILE, THEAGGREGATION OF THE COHERENT GENERATORS IS THE MOST IMPORTANT STEPIN LARGE POWER GRIDS INTENTIONAL DEFENSIVE SPLITTING TO GUARANTEETHE DYNAMIC STABILITY OF THE CREATED ISLANDS AND REDUCE THECOMPUTATIONAL BURDEN OF THE HUGE INITIAL SEARCH SPACE. THEPROPOSED METHOD OF THIS PAPER DETERMINES THE COHERENT MACHINESBASED ON THE ELECTRICAL PARAMETERS OF THE SYNCHRONOUS GENERATORSINSTEAD OF THE DYNAMICAL PARAMETERS SUCH AS ROTOR ANGLE OR SPEEDCURVES, SPEED PARTICIPATION FACTORS, ETC. THE STATOR AND EXCITATIONWINDINGS FLUX, EXCITATION VOLTAGE AND CURRENT HAVE BEEN PROPOSEDAS COHERENCY INDICES. THE PROPOSED COHERENCY BASED AGGREGATIONHAS BEEN CARRIED OUT ON NEW ENGLAND 39-BUS TEST SYSTEM. THETIME-DOMAIN SIMULATION RESULTS DEMONSTRATE THE EFFECTIVENESS ANDCAPABILITY OF THE PROPOSED METHOD TO IDENTIFY THE COHERENTMACHINES FOLLOWING A SEVERE CONTINGENCY.
