Solar shield: forecasting and mitigating space weather effects on high-voltage power transmission systems

摘要: In this paper, central elements of the Solar Shield project, launched to design and establish an experimental system capable forecasting space weather effects on high-voltage power transmission system, are described. It will be shown how Sun–Earth data models hosted at Community Coordinated Modeling Center (CCMC) used generate two-level magnetohydrodynamics-based forecasts providing 1–2 day 30–60 min lead-times. The Electric Power Research Institute (EPRI) represents end-user, industry, in project. EPRI integrates forecast products online display tool information about conditions member utilities. also evaluates economic impacts severe storms systems. analysis quantify value generated system. first version is currently running real-time CCMC. An initial system’s capabilities has been completed, further being carried out optimize performance Although results encouraging, definite conclusions can given only after more extensive analysis, implementation automatic evaluation process using forecasted observed geomagnetically induced currents from different nodes North American final output a recommendation for optimal that may transitioned into operations.
