Abstract

Smart city deals with the problems of rapid urbanization and population growth by optimal utilization of all available resources. There are other driving factors such as clean energy programmes, a low carbon economy and distributed energy resources that are included in a smart city concept. Therefore, in this article, the authors proposed a clean energy generating model by utilizing the kinetic energy of vehicles over a speed breaker. The article focused on the design, modelling, and simulation of an electromechanical system for generating electrical power from the kinetic energy of vehicles passing over speed breakers. To facilitate simulation, a model of the electromechanical system is developed in MATLAB/Simulink. Further, MULTISIM 14 software is utilized for power electronic device modelling and simulation. Simulation results for power generation are obtained considering four units of rotational induction generators and two units of translational induction generators.
