In Great Britain (GB), robustly assessing this contribution directly from power system data (i.e., metered wind-supply and electricity demand) is difficult as extreme peaks occur infrequently (by definition) and measurement records are both short and inhomogeneous.Atmospheric circulation-typing combined with meteorological reanalysis data is proposed as a means to address some of these difficulties, motivated by a case study of the extreme peak demand events in January 2010. A preliminary investigation of the physical and statistical properties of these circulation types suggests that they can be used to identify the conditions that are most likely to be associated with extreme peak demand events.Three broad cases are highlighted as requiring further investigation. The "High-overBritain" anticyclone, is found to be generally associated with very low winds but relatively moderate temperatures (and therefore moderate peak demands, somewhat in contrast to the classic "low-wind cold-snap" that is sometimes apparent in the literature). In contrast, both longitudinally-extended blocking over Scotland/Scandinavia and latitudinally-extended troughs over western Europe appear to be more closely linked to the very cold GB temperatures (usually associated with extreme peak demands). In both of these latter situations, wind-resource averaged across GB appears to be more moderate.1

a b s t r a c tWind and solar power have experienced rapid cost declines and are being deployed at scale. However, their output variability remains a key problem for managing electricity systems, and the implications of multi-day to multi-year variability are still poorly understood. As other energy-using sectors are electrified, the shape and variability of electricity demand will also change. We develop an open framework for quantifying the impacts of weather on electricity supply and demand using the Renewables.ninja and DESSTINEE models. We demonstrate this using a case study of Britain using National Grid's Two Degrees scenario forwards to 2030.We find the British electricity system is rapidly moving into unprecedented territory, with peak demand rising above 70 GW due to electric heating, and intermittent renewable output exceeding demand as early as 2021. Hourly ramp-rates widen by 50% and year-to-year variability increases by 80%, showing why future power system studies must consider multiple years of data, and the influence of weather on both supply and demand. Our framework is globally applicable, and allows detailed scenarios of hourly electricity supply and demand to be explored using only limited input data such as annual quantities from government scenarios or broader energy systems models.

“…Primary and secondary reserve in this work are provided by online units (thermal, hydro, EVs), whereas tertiary control can be provided from both online and offline quick-start (CCGT, OCGT) units. Primary control reserve, both up and down, are at constant values of 1.9 GW as they corresponds to the reserve for frequency response in UK power system [38]. Secondary and tertiary control are time vectors of constant values.…”
