Assessing the Applicability of Vertical Transportation in Power System Inertial Support

Abstract

loads could be equipped to monitor the system frequency and automatically reduce their consumption or switch off when a fast rate of change of frequency (RoCoF) is detected [7].

Potential of aggregated escalator loads in demand response

“…Besides main areas of application, escalators can be found in hospitals, schools, factories, sport arenas, office buildings and museums [24]. According to European Lift Association (ELA), there were about 137 000 escalators in Europe in 2016 [25] and approximately 9000 in the Nordics [26,27], while around 5 000 are being installed every year in the EU [28]. National Elevator Industry states that escalators carry approximately 105 billion passengers per year in the US alone [29].…”
