“…Models such as those used by Billington and Khan [7] address the degree to which both adequacy and security are satisfied by studying the large number of NERC-mandated failure cases. In general, simulations based on these types of models curtail energy consumption in response to increasing network constraints.…”

The reliability of electric transmission systems is examined using a scale-free model of network topology and failure propagation. The topologies of the North American eastern and western electric grids are analyzed to estimate their reliability based on the Barabási-Albert network model. A commonly used power system reliability index is computed using a simple failure propagation model. The results are compared to the values of power system reliability indices previously obtained using standard power engineering methods, and they suggest that scale-free network models are usable to estimate aggregate electric grid reliability.

Abstract:Since the advent and integration of information technology into power industry, the complexity of modern power systems and advances in the power industry toward restructuring, the system models and algorithms of traditional reliability assessment techniques are becoming obsolete as they suffer from nonrealistic system models and slow convergence (even non-convergence) when multi-level contingencies are considered and the system is overstressed. To allow more rigor in system modeling and higher computational efficiency in reliability evaluation procedures, this paper proposes an analytically-based security-constrained adequacy evaluation (SCAE) methodology that performs bulk power system reliability assessment and gave an in depth analysis of the concept of the state of the art in bulk power system reliability assessment. Bulk power system reliability assessment is an important procedure at both power system planning and operating stages to assure reliable and acceptable electricity service to customers.

“…OPF problems are formulated to minimize the load curtailment using remedial actions. Linear programming algorithms for remedial actions that control active power [6][7][8][9] and reactive power [10] are derived. Some techniques, including the simplex method and the interior point method [11], are applied to solve the formulated optimal power flow problem.…”
