Mobile and Portable De-Icing Devices for Enhancing the Distribution System Resilience Against Ice Storms: Preventive Strategies for Damage Control
Climate change has reportedly increased the frequency and intensity of extreme weather events such as heatwaves, heavy rains, hurricanes, tornados, flood, fire, and ice storms. Ice storms are considered one of the most severe natural disasters that can disrupt people’s daily lives and incur infrastructural damages. Ice storms are the leading cause of large-scale power outages in the United States and elsewhere during the winter season. The damage caused by ice storms can easily result in major power outages, blackouts, and at times shut down entire metropolitan areas.

A Numerical Approach for Hybrid Simulation of Power System Dynamics Considering Extreme Icing Events
The global climate change leads to more extreme meteorological conditions such as icing weather, which have caused great losses to power systems. Comprehensive simulation tools are required to enhance the capability of power system risk assessment under extreme weather conditions. A hybrid numerical simulation scheme integrating icing weather events with power system dynamics is proposed to extend power system numerical simulation. A technique is developed to efficiently simulate the interaction of slow dynamics of weather events and fast dynamics of power systems. An extended package for PSS/E enabling hybrid simulation of icing event and power system disturbance is developed, based on which a hybrid simulation platform is established.
