Security and Resilience Enhancement of Future Smart Grid: Models and Methods

The modern power system is moving towards the future smart grid where high penetration of renewable energy sources and power electronics is expected. While enabling the realization of low-carbon power systems, it reduces the security margin and resilience of power systems against extreme events, e.g., extreme weather events and deliberate attacks. Meanwhile, power systems suffer from increased vulnerabilities and security risks due to growing integration of information and communication technologies (ICT). As the consequences of power system interruptions can be disastrous, enhancing the security and resilience of power systems with practical methods has become a critical task for the power industry.

With high penetration of renewables and deep integration of ICT in power systems, many challenges require further research to achieve secure and resilient operations of power grids. State-of-the-art techniques and technologies are needed to prepare the power systems for potential threats from extreme events. This Research Topic aims to publish Original Research and visionary Review papers on the models and methods for the security and resilience analysis and enhancement of future power systems with high penetration of renewables, power electronics and ICT.

Topics of interest include, but are not limited to:
• Evolution roadmap towards low-carbon, climate-resilient power systems;
• Optimal planning of power systems for resilience enhancement;
• Risk evaluation and management of power systems against extreme events;
• Vulnerability and critical component identification of cyber-physical systems;
• Modeling of attack and failure propagations in cyber-physical systems;
• Mitigation methods against deliberate attacks on cyber-physical systems;
