Ensuring Power System Resilience in the Face of Extreme Events

As a vital infrastructure, power systems must withstand rare yet severe incidents like natural disasters to prevent the collapse of essential services. To effectively prepare for such extreme events, it's crucial to distinguish between reliability, resilience, and robustness.

Resilience is an emerging technical concept in power systems and other infrastructures, distinct from reliability, robustness, and security:

- Reliability focuses on high-probability, low-impact events.

- Resilience addresses high-impact, low-probability events.

- Robustness denotes a system's intrinsic stability amidst uncertainties.

Resilience encompasses restoration and recovery mechanisms, influenced by human decisions and operational procedures. Unlike reliability, resilience investments may involve societal contributions due to their broader social impact, necessitating new cost-benefit analyses. Resilience-driven decisions diverge from traditional security and reliability-based investments. Community impact and response are integral to resilience, underscoring the need for separate yet coordinated studies. With increasing natural hazards and threats, bolstering system resilience is imperative, particularly amid the rise of electric transportation and ICT dependencies.

Key Points:

- Resilience addresses extreme, infrequent events with widespread and prolonged impacts.

- It is crucial in the face of escalating climate-related challenges affecting power systems and renewable energy sources.

Resilience Factors, Tasks, and Measures:

- Planning and Operation Tasks: Ranging from short-term preventive actions before events to emergency responses and infrastructure recovery post-event.

- Customer/External and Operator/Internal Perspectives: Highlighting service delivery quality to customers and system operators' capabilities.

To boost system resilience, various activities can be undertaken, including:

- Resilience-oriented planning for potential events.

- Preventive responses for predicted events.

- Emergency responses during or after events (e.g., network reconfiguration, provisional repairs).

- Power system service restoration and infrastructure recovery.

- Learning from events to enhance resilience and performance.
