The rapid adoption of electric vehicles and smart power electronic devices has significantly heightened electricity demand, challenging the resilience of traditional power networks. In response, power systems are undergoing digitalisation to form remotely controlled smart grids. However, this transition exposes vital infrastructure to severe cyber threats, demonstrated by real-world disruptions such as the destructive cyber-attack on Ukraine's electricity distribution networks. Addressing these risks requires robust cybersecurity strategies that evaluate potential attack vectors alongside viable defence mechanisms to preserve continuous supply. By synthesising academic findings with industry practices, established methods can be merged with newer technologies to secure critical grid assets, particularly substations. Implementing these defensive frameworks provides a structured approach for securing modern power infrastructure against evolving digital disruption.
Modern electrical grids increasingly rely on internet-connected digital controls to manage high demand from new technologies. When these digital systems are attacked, entire communities can suffer blackouts, financial damage, and disrupted services. Strengthening grid cybersecurity ensures that electricity networks remain dependable, preventing hostile intrusions from cutting off essential power supplies to homes, hospitals, and critical regional infrastructure.
The insights offer guidance for power system operators, utilities, and infrastructure policymakers seeking to protect vital assets such as substations. Potential applications focus on integrating conventional security protocols with modern defensive technologies to safeguard smart grid control systems. Because the work delivers recommendations and strategic evaluations based on research and industry expertise rather than a tested software product, it represents early-stage guidance for grid security implementations.

Recent technological advancements in the energy sector, such as the proliferation of electric vehicles, and smart power electronic devices, have substantially increased the demand for reliable and quality power supply. This surge in energy consumption has posed significant concerns for traditional power systems regarding the systems’ resilience and reliability. To address these challenges, power system engineers and researchers have proposed the digitalization of power systems, resulting in remotely controlled and operated smart grids. However, the transition towards smart grids has introduced new vulnerabilities, specifically in the form of cyber-attacks. One notable example is the recent malicious attack on the Ukrainian power system, which left three distribution networks destroyed, causing losses and damage to thousands of customers. In an era marked by rapid technological advancement, the security of modern power infrastructure against malicious cyber-attackers has emerged as a paramount concern for power system operators. This paper presents a comprehensive examination of cybersecurity strategies aimed at strengthening the resilience and reliability of modern power systems. By thoroughly analyzing the various cyber-attacks and effective defence strategies, it is evident that cybersecurity plays a crucial role in maintaining a continuous power supply and reducing the impact of potential contingencies. The study further provides valuable perspectives on the changing landscape of cyber threats faced by power infrastructure by combining insights from advanced research and industry expertise. By combining conventional techniques and cutting-edge technologies, valuable recommendations are provided for improving the cybersecurity of the power system and protecting vital grid assets, such as substations. This paper serves as an essential resource for policymakers, industry practitioners, and researchers seeking to understand the complex relationship between cybersecurity and modern power systems.
