power system protection is essential for maintaining the reliability and stability of electrical grids, ensuring continuous service, and preventing catastrophic failures. As powersystems evolve to incorporate renewable energy and increasingly complex configurations, the role of Artificial Intelligence (AI) in enhancing protection mechanisms has become indispensable. This paper reviews the integration of AI in power system protection, highlighting its potential to improve fault detection, adaptive protection strategies, predictive maintenance, and real-time monitoring. AI techniques, including machine learning, deep learning, and expert systems, offer significant advancements in overcoming the limitations of traditional protection schemes. Furthermore, the integration of AI contributes to the development of resilient and sustainable infrastructure, supports innovation in intelligent urban systems, and enhances the reliability of modern power grids. Despite its promising potential, challenges such as data scarcity, model scalability, and real-time processing need to be addressed for effective implementation. This review synthesizes the current literature on AI applications in power system protection, comparing them with conventional methods, and provides information on future research directions and practical applications to improve energy reliability, sustainable urban development, and industrial innovation.

In view of the sweeping changes that have taken place in the electricity supply industry it is now, more than ever before, of vital importance that senior managers have easy access to processed data and information. This must provide them with knowledge of powersystems and their constituent components. The implementation of Intranet technologies in protection and control systems will enable free and flexible acquisition of powersystem information at the appropriate location.

As conventional generation sources continue to be replaced with inverter-based resources, the traditional fixed overcurrent protection schemes used at the distribution level will no longer be valid. Adaptive protection will provide the ability to update the protection scheme in near real-time to ensure reliability and increase the resilience of the grid. However, knowing and detecting when to update protection parameters that are calculated with an adaptive protection algorithm to prevent unnecessarily communicating with relays still needs to be understood. The proposed method provides a sensitivity analysis to understand when it is necessary to issue new parameters to the relays. The results show that settings do not need to be issued at each available time step. Instead, the proposed sensitivity analysis method can be used to ensure that only the imperative protection parameters are communicated to the relay, allowing for more optimal utilization of the communications. The results show that the sensitivity analysis reduces the settings communicated to the devices by 93% over the year.

Across the United States, utility companies rely on power generated from long distances to provide power for cities and customers. system stability is a tremendous effort that requires strong physical infrastructure and requires ways to monitor and protect the powersystems over long distances and varying terrain. This article researches power system protection and models a typical powersystem using Real Time Digital Simulator, RSCAD, and SEL 311-L relays.

During a real-time powersystem event, a system operator needs to conservatively reduce operating limits while the changing system conditions are analyzed. The time it takes to develop new operating limits could affect millions of transmission system users, especially if this event is classified by NERC as a Category D type event (extreme events resulting in the loss of two or more bulk electric system elements). Controls for the future grid must be able to perform real-time analysis, identify new reliability risks, and set new SOLs (system Operating Limit) for real-time operations. In this paper we are developing "Resilience Metrics" requirements that describe how systems operate at an acceptable level of normalcy despite disturbances or threats. We consider the interdependencies inherent in critical infrastructure systems and discuss some distributed resilience metrics that can be in current supervisory control and data acquisition (SCADA) to provide a level of state awareness. This level of awareness provides knowledge that can be used to characterize and reduce the risk of cascading events. A "resilience powersystem agent" is proposed that provides attributes to measure and perform this metrics.

In recent years, distributed energy resources (DERs) have been increasingly integrated into powersystems that affect grid management and operations. Since the operating conditions of DERs vary greatly and are more intermittent than those of conventional energy systems, powersystems are experiencing greater stability problems. Modular controllable transformers (MCTs) have been proposed as an optimum solution to address these issues. MCTs are specialized transformers that utilize fractionally rated power converters and perform several grid support functions in addition to isolation and voltage conversion. protection requirements for MCT have not yet been defined in the standards. This paper aims to improve the performance and protection of MCTs by proposing and validating their protection schemes. These protection schemes include differential protection, overcurrent relay, and under and overvoltage relay. These protection schemes have been implemented, and simulation results that validate their effectiveness are presented in this paper.

The Internet of Things (IoT) approach has been one of the major trend technologies in the last years. This concept brings advantages in many areas including the power system protection, where a real time information can be transmitted and processed faster than actual protectionsystems. In this paper a real case implementation of an IoT Gateway, named Smart Grid Gateway (SGG), is proposed to concentrate relevant protection information and build an adaptive protectionsystem, logical selectivity philosophy, and self-healing concept. The implementation are an outcome of the R&D project hosted by ENEL Distribuiciio Silo Paulo called Urban Futurability.

We have developed an EMTP model of a resistance-type and a rectifier-type for super-conducting fault current limiter (SFCL) and defined their parameters which a user specifies when he plans to introduce an SFCL into a powersystem. Using these models, we propose the setting method of these parameters so as not to affect the response of protective relays when SFCLs operate.
