Resilience of the Cyber-Physical Power Grid
Abstract: The electric power grid is a complex cyber-physical system that forms the lifeline of a modern society. Its reliability/security/resilience is of paramount importance to national security and economic well-being. The increased reliance on information and communications technology in the smart grid significantly increases vulnerabilities, which underscores the importance of cyber security. Cyber-physical system security of the power grid is a critical area encompassing vulnerability assessment, anomaly detection, and mitigation for substations and the Supervisory Control and Data Acquisition systems. On the other hand, resilience of the physical power grid with respect to extreme events is an emerging area that requires new concepts, metrics, and technologies. This presentation will discuss how AI/ML, including reinforcement learning and multi-agent systems, serves as foundational technologies for resilience of the cyber-physical power grid.

Power System Inertial and Frequency Response
Climate change and the pursuit of energy self-sufficiency are accelerating the transition to green power generation, which has led to a significant share of variable renewables in power systems worldwide. As a result of the high penetration of RES units, especially inverter-coupled wind turbines and photovoltaics (PV), the dynamics of modern electric power systems have changed. At the same time, the increasing variability of demand due to new loads such as electric vehicles and electric heating reduces the overall predictability of demand. As a result, the operation of power systems has become a challenge that requires new approaches to monitoring, protection and control. On the other hand, the availability of smart technologies, e.g. sensor and ICT technology, has opened up new paradigms for addressing new challenges. The presentation aims to address dynamic problems in future low inertia power systems and to develop new approaches for monitoring and control. The focus will be on the inertial response of power systems and a number of possible solutions that can be used to improve the frequency response of the system after disturbances.
