This paper proposes a methodology for curtailment of optimal load accounting operating and stability inequality constraints at selected buses using differential evolution (DE). In this paper Schur's inequality of load flow Jacobian is a proximity indicator and load buses for load shedding have been selected based on the sensitivity of proximity indicator with respect to load shed. The algorithm accounts inequality constraints not only in present operating condition but for predicted next interval load. The algorithm has been implemented on standard 6-bus test system. Results have been compared with those obtained using particle swarm optimization (PSO) and coordinated aggregation based PSO (CAPSO).
