The Fragile Grid: The Physics and Economics of Security Services in Low-Carbon Power Systems
Worldwide, there are unstoppable forces toward low-carbon power systems that can support the fight against climate change and help solve the security of supply issues in many countries. Low-carbon grids are likely to be characterized by substantial renewable energy sources, both centralized and distributed, combined with intelligent and dynamic demand-side technology and multisector electrification (including heating, transport, and future fuels). In this context, successfully resolving the “affordability-sustainability-reliability” energy trilemma is crucial for paving the way to low-carbon energy futures.

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.
