“…Unlike their QSS counterpart, the literature on dynamic models of cascading failure is relatively limited -see for example [2]- [9] and references therein. The papers can be broadly divided into three categories.…”

“…Paper [2] proposed a multi-time period two-stage stochastic mixed-integer linear optimization model to specify the optimal investment on the network to enhance system's resilience against natural disasters. The model uses dynamic simulations for cascading failure simulation, and the multi-time period restoration, modeled through a DC optimal power flow initialized by the solution of dynamic simulation.…”

“…Although references in the second [5] and the third category [2]- [4] have made valuable contributions, they still suffer from the computational burden faced by the simulation of dynamic models. For example, [3] effectively simulated 88 cases in Polish system out of 1, 200 that can be called cascades because most (1, 081) did not have any dependent outages (i.e., any further outages following the initial outages) leading to short simulations, while 31 diverged.…”

“…At the outset, we clarify that our goal is to perform deterministic cascading failure analysis, which implicitly assumes that all systems act as expected during the cascade, i.e., potential mistripping of protective relaying and other malfunctions are not considered during the cascade [2], [3]. This is in contrast to probabilistic approaches that consider that the evolution of the power system after an initial set of contingencies can follow multiple trajectories, see for example [4], [5].…”

The ground truth for cascading failure in power system can only be obtained through a detailed dynamic model involving nonlinear differential and algebraic equations whose solution process is computationally expensive. This has prohibited adoption of such models for cascading failure simulation. To solve this, we propose a fast cascading failure simulation approach based on implicit Backward Euler method (BEM) with stiff decay property. Unfortunately, BEM suffers from hyperstability issue in case of oscillatory instability and converges to the unstable equilibrium. We propose a predictor-corrector approach to fully address the hyperstability issue in BEM. The predictor identifies oscillatory instability based on eigendecomposition of the system matrix at the post-disturbance unstable equilibrium obtained as a byproduct of BEM. The corrector uses right eigenvectors to identify the group of machines participating in the unstable mode. This helps in applying appropriate protection schemes as in ground truth. We use Trapezoidal method (TM)-based simulation as the benchmark to validate the results of the proposed approach on the IEEE 118-bus network, 2, 383-bus Polish grid, and IEEE 68-bus system. The proposed approach is able to track the cascade path and replicate the end results of TM-based simulation with very high accuracy while reducing the average simulation time by ≈ 10 − 35 fold. The proposed approach was also compared with the partitioned method, which led to similar conclusions.

“…This means the model captures both real and reactive power flows, and voltages. We compare the optimal resiliency investments to those obtained when the model uses a linear power flow approximation (DC OPF), as in [5], [6]. Additionally, we provide results justifying OTS in a resiliency setting and perform an AC feasibility study to demonstrate the optimal investment, unit commitment, and OTS decisions with the relaxed SOCP model are far more accurate compared to the linear DC model.…”
