Elevator Regenerative Energy Applications with Ultracapacitor and Battery Energy Storage Systems in Complex Buildings

Due to the dramatic growth of global population, building multi-story buildings has become a necessity, which strongly requires installation an elevator regardless type being built. This study focuses on households, are second-largest electricity consumers after transportation sector. In residential buildings, elevators impose huge costs because they used by many consumers. The novelty this paper is implementing Hybrid Energy Storage System (HESS), including ultracapacitor (UCES) and Battery (BES) system, in order reduce amount power energy consumed buildings. control strategy includes two main parts. first stage, indirect field-oriented implemented provide new features flexibility system take benefit regenerative received from elevator’s motor. second novel proposed HESS efficiently. context, only fed regenerated so stored UC can be peak consumption. Meanwhile, BES supplies common electrical loads building, e.g., washing machines, heating services (both boiler heat pump), lighting, helps achieve nearly zero building.
