SPTS consists of a specified number of electric bus stops that are present through the ring road of the Guwahati city, Assam, India. Every bus stop consists of a high capacity energy storage device (ESD) and these ESDs are responsible to communicate SPTS with the grid. ESDs receive energy from the grid during off-peak period and send its stored energy back to the grid during peak period. The charging and discharging performance of ESD mitigates the peak power demand of the grid (normally the grid remains under energy deficit condition during peak period). Also, ESD supplies energy to the electric buses (supercapacitor based energy storage system is used) for 24 h and performs the isolated operation of electric buses with the grid. The electric buses have been used to perform the mass transportation through the ring road of the Guwahati city. SPTS dependence on the grid has been reduced by providing a solar plant at every bus stop.enELECTRONICS AND ELECTRICAL ENGINEERINGThesis
