“…Proactive resilience is sometimes called preventative or defensive resilience. Proactive islanding is discussed in [18][19][20][21][22]. Defensive islanding techniques are predominantly a transmission system strategy, but a similar methodology can be applied to large distribution systems with distributed energy resources (DERs).…”

Distribution system resilience is an emerging topic of interest given an increasing number of extreme events and adverse impacts on the power grid (e.g. Hurricane Maria and Ukraine cyber-attack). The concept of resilience poses serious challenges to the power system research community given varied definitions and multivariate factors affecting resilience. The ability of nature or malicious actors to disrupt critical services is a real threat to the life of our citizens, national assets and the security of a nation. Many examples of such events have been documented over the years. Promising research in this area has been in progress focused on the quantification and in enabling resilience of the distribution system. The objective of this study is to provide a detailed overview of distribution system resilience, the classification, assessment, metrics for measuring resilience, possible methods for enabling resilience, and the associated challenges. A new multi-dimensional and multi-temporal resilience assessment framework is introduced along with a research roadmap outlining the future of resilience to help the reader conceptualise the theories and research gaps in the area of distribution system cyber-physical resilience.

Background: An increase in the load demand has been forcing the electrical components to work near their allowable limits. The transformation of the power system in terms of technology and geographical stretch has imposed the necessity of employing advanced protection schemes in the system. The system integrity protection scheme (SIPS) has evolved as an effective measure with the gradual sprawl of the conventional grid with local measurements to a smart grid with wide-area measurement system. Aims: SIPS is a rapidly growing field in the power system and thus the study of its performance analysis, implementation methods, and applications is necessary. This paper provides a comprehensive overview of SIPS technology. Materials & Methods: In this paper, SIPS definition and classification are briefly discussed. SIPS normalization schemes that include load shedding, controlled islanding, generation rejection, ou-of-step prediction, relay settings are elaborated. To implement these normalization schemes, various methods such as index-based, optimization-based, WAMS based, EAC based, and ML-based are discussed and compared. Finally, a comparative assessment is framed based on SIPS applied for different power system issues such as transient instability, voltage instability, overloading, line contingency, protection security, etc. Results: It is observed that most of the proposed SIPS are implemented for improving transient stability. The preferred solution for implementing the SIPS by the researchers is load shedding. It is also observed that there is a lack of implementation of SIPS with renewable energy systems.

“…However, immediate operation of all control actions in an ICI approach is not practical. 35 Therefore, a time decomposition for modeling fast and slow corrective actions in ICI is required to enhance practicality. Using the proposed time decomposition, the fast and slow corrective actions are decomposed and are more accurately modeled considering their interactions.…”

To improve electrical energy system resilience under catastrophic events, an efficient intentional controlled islanding (ICI) model is proposed in this article. The proposed remedial action relies on a new mixed integer linear programming (MILP) model which aims at minimizing the overall energy curtailment, power flow disruption, and generation and demand re-dispatches through a cost-based objective function. Another innovative characteristic of this model is demand response (DR) inclusion in the proposed ICI. To improve the balance between demand and supply of electricity, DR can be employed as an effective strategy in the ICI problem. In addition, another main original feature of the proposed model is considering energy storage units (ESUs) in each resulted island after the splitting process. To provide enough time for the system operator to re-dispatch the islands and to improve frequency stability of islands, a charging/discharging scheme is proposed for ESUs during ICI. Moreover, a new time decomposition is proposed to accurately model the fast and slow corrective actions considering their interactions. Using this time decomposition, energy curtailments, considering their period durations, are treated as decision variables in the ICI problem to minimize involuntary load shedding as the most expensive corrective action. The results of scrutinizing the proposed ICI framework on the IEEE 118-bus test system illustrate its performance. In addition, the results of the proposed ICI approach are compared with the results of other ICI models to illustrate the effectiveness of the new features of the proposed approach.
