A Technical Review on Self-Healing Control Strategy for Smart Grid Power Systems

Abstract

The various advanced technologies incorporated in the existing power system to operate in smarter and to provide continuity of power supply without any disturbances. Still, it was few threats that disrupting the electrical network to manage the power demand such as: complexity of the power grid; vulnerability to faults; energy efficiency; and renewable energy integration. The above challenges indicate the perception of smart grid (SG). The smart grid design is economic, competent, intelligent and secured grid was needed to manage the above-mentioned issues. Self-healing is the most essential characteristics of a smart grid. The implementation of self-healing control strategy in the smart grid is one of the prolong challenge. It is the capability of the power system network to restore naturally the network when the fault occurs. It gives primary assurance to the smart grid protection. Apart from this, the implementation of various control strategies assist accomplishing the safe functioning, enhancing the stability of the grid. This paper presents the self-healing control strategy in the context of smart grid power systems. The significant advancements developed in the transmission, distribution, micro grid as a result of power electronics converters presented. Then, the information and communication technologies, software tools and measurements which can be employed for winning crucial smart grid self-healing action will be discussed.

Enhancing Resilience: Smart Grid Cybersecurity and Fault Diagnosis Strategies

“…Comprehensive Risk Assessment: Conducting a thorough risk assessment is essential for identifying potential cybersecurity vulnerabilities and prioritizing mitigation efforts. This includes assessing the security posture of grid components, identifying potential attack vectors, and evaluating the potential impact of cyber threats on grid operations [50,51]. Intrusion Detection Systems (IDS): Implementing intrusion detection systems enables utilities to monitor network traffic and detect suspicious activity in real-time [52].…”

A hierarchical performance evaluation approach for the sustainability of smart grid

“… Self-healing capability : A self-healing grid is meant to detect and respond to problems automatically. It protects the power infrastructure and the people who work on it while also providing information that allows the correct people as well as systems to make the right decisions at the right time (Sarathkumar et al , 2021). Moreover, a self-healing grid uses digital components and real-time communications to constantly monitor its own electrical characteristics, resulting in a more stable and efficient system. Environmental awareness : Because of concerns about the depletion of conventional fuels and growing environmental awareness, the importance of developing a smarter grid has increased and attracted a diverse variety of academic and corporate stakeholders (Tozak et al , 2022).…”

Providing a New Multiobjective Two-Layer Approach for Developing Service Restoration of a Smart Distribution System by Islanding of Faulty Area

“…Te system's ability to quickly detect faults, take necessary actions to reduce the adverse efects of faults, and quickly restore the system to a stable operating state is defned as self-healing [1]. Te structure of the smart grid, while implementing the self-healing strategy, is categorized into smart transmission grid, smart distribution grid, and smart MGs [2]. Te method of diferential evolution algorithm is chosen in [3] to optimize the performance of network MGs in self-healing mode.…”
