Power system resilience (end user) and critical infrastructure

Abstract

Power system resilience refers to the electrical system's ability to withstand disruptive events or quickly recover from them, retaining or quickly resuming normal operation. From the end user's perspective, this traditionally quantifies the grid's ability to ensure a continuous power supply. However, end users are now heavily dependent on numerous critical infrastructures, such as communications and data services. These critical infrastructures can be used by millions of users and are vital to their safety. Hence, the power system must ensure power supply to each end user and guarantee the continuous operation of all critical infrastructures. Power electronics plays a vital role in power system and infrastructure resilience improvement and will be central in future grids.
