FERC to look at grid reliability
Spurred by last week’s power grid failure in Texas, the Federal Energy Regulatory Commission on Monday announced that it will open a new proceeding to examine the threat that climate change and extreme weather events pose to electric reliability. The proceeding, FERC said, will investigate how grid operators prepare for and respond to these events, including droughts, extreme cold, wildfires, hurricanes, and prolonged heat waves.

The basic concepts related to the phenomenon of field line stochastization through external magnetic perturbations, e.g., resonant magnetic surfaces, magnetic islands, overlap of island chains, stochastic instability, Kolmogorov length, field line diffusivity, etc., are discussed. Different models for description of transport of heat, background and impurity particles in stochastic magnetic field are presented. Stochastization impacts on the plasma rotation, radial electric field and electromagnetic fluctuations in the plasma are described. Mechanisms responsible for mitigation of the edge localized modes, ELMs, are introduced.
