The novelty of this paper is implementing a Hybrid Energy Storage System (HESS), including an ultracapacitor Energy Storage (UCES) and a Battery Energy Storage (BES) system, in order to reduce the amount of power and energy consumed by elevators in residential buildings. The control strategy of this study includes two main parts.
Energy recovery control in elevators with automatic
The proposed control strategy utilizes the reverse power flow to accumulate energy on the storage device, that will be later utilized during lifting trips. Excess recovered energy is injected to the grid. The storage device is controlled to maintain a minimum energy level for emergency situations, to safely guarantee landing of the elevator''s cart.
Hydraulic Elevators – Configuring the Power Unit, Part II
cycle of the elevator. The Fluid in the Power Unit: Oil Hydraulic oil transmits the energy generated by the pump to the cylinder. Thus, it is an important medium of energy transfer, and its selection should be well considered. Ideally, the hydraulic oil should have the following characteristics: 1) Stable viscosity with changing pressure and ...
A Novel Reconstruction Approach to Elevator Energy Conservation Based on a DC Micro-Grid in High-Rise …
At present, researchers have used energy storage devices to store elevator regenerative energy [38–44]. The papers [38,39] have presented the operational simulation of an elevator with supercapacitor in MATLAB. The paper [40] proposes a supercapacitor-based

The structure and control strategies of hybrid solid gravity energy storage …
In this paper, we propose a hybrid solid gravity energy storage system (HGES), which realizes the complementary advantages of energy-based energy storage (gravity energy storage) and power-based energy storage (e.g., supercapacitor) and has a promising future application. First, we investigate various possible system structure …
Types Of Elevators
Gear-less traction elevators are capable of speeds up to 20 mps and they have a maximum travel distance of around 500 m so they are the only choice for high-rise applications. Geared traction elevators are middle of the road in terms of initial cost, ongoing maintenance costs, and energy consumption. Gear-less traction elevators have a high ...
Energy recovery control in elevators with automatic rescue application …
Energy recovery from elevators'' systems is proposed. •. Energy storage using supercapacitors and lithium-ion batteries is implemented. •. Bidirectional power flow is controlled to use the stored energy as auxiliary supply to the load without exchanging with the grid. •. Emergency energy level is maintained and used in automatic rescue ...
