Improving Grid Resilience Using High-Voltage dc: Strengthening the Security of Power System Stability

With a heavy dependence on electric power worldwide for critical services ranging from communication and banking to water treatment and medical care, the availability of reliable electricity proves essential for a productive society in the 21st century. Even short interruptions in service may result in significant lost revenue and widespread disruption in large grids serving tens of millions of customers. The combination of such dependence on electric power along with classical threats (e.g., severe weather) and modern concerns (e.g., cyberattacks) creates an imperative for grid resilience.
