The title of thesis is “Models for evaluating the power consumption of elevators – The perspective of power systems and demand response”

A functional power system necessitates a constant balance in demand and supply of electricity. Due to the increasing ratio of variable renewable energy sources, such as wind and solar power, which cause fluctuations and uncertainty in the supplied power, the demand side has to compensate this by becoming more flexible than previously. As a result, the industry and academia are seeking for new cost-efficient means to add controllability on the consumption side of the power system. The active participation of the consumption side in the power system balancing is also referred to as demand response.

This dissertation analyzes the potential of utilizing elevators (lifts) as a controllable electrical load to participate in the demand response. To reach this objective, the dissertation focuses on providing methods for modeling the elevator power consumption in high-resolution as well as the long-term energy consumption.  These methods combined with the passenger traffic simulation and consequent elevator usage provide means to understand the effectiveness of employing elevators in demand response from the perspective of obtainable change in power consumption and the impact on the passengers and overall traffic handling capacity.
