Optimal number of e-buses in the solarassisted smart public transit system and its failure analysis

This study presents an optimal number of electric buses in the solar-assisted smart public transit system and its failure analysis. Electric buses are used to perform the mass transportation in the Guwahati city, Assam, India. The charging points have been provided through the ring road of the city to charge the electric buses. Every charging point consists of a highcapacity energy storage device (ESD) and the solar plant for achieving the smooth functionality of the transportation system. Optimal numbers of electric buses have been determined as a function of the load, the ESD, the solar plant and the passenger total. Simulations have been carried out to show the system response for the optimal number of electric buses and for the failures that exist in the system. Every charging point consists of a fuzzy logic controller to control the power flow among the grid, ESD and the solar plant.
