A hybrid AC/DC architecture is a system that consists of both alternating current (AC) and direct current (DC) power sources and distribution systems. Hybrid AC/DC microgrid has several advantages over conventional AC-based building distribution network. For instance, it has higher energy efficiency, better reliability, and greater flexibility. Lift system is one of the largest energy consumer in building. It is crucial to tackle climate change by ensuring that the new and existing buildings are energy-efficient and sustainable. Therefore, this paper will investigate a hybrid AC/DC microgrid architecture that can integrate all the lifts in a building and utilize the energy generated during regenerative braking mode. We can also improve the building energy efficiency through the reduction of multiple conversion loss. In addition, a MATLAB/Simulink design will be presented in this report.
