| Abstract | Saint Martin is a popular tourist destination and the only coral island in Bangladesh. A huge number of travelers visit every year, from home and abroad. However, lack of proper planning as well as severe electricity shortages are hindering its transformation towards a smart city. The existing solar/diesel system is insufficient to meet rising load demand, causing visitor dissatisfaction. This study presents a smart city model for Saint Martin Island driven by internet of things, which includes a grid-independent microgrid system that integrates wave, solar, wind, and biodiesel as key energy sources. Firstly, the implementation of internet of things can effectively optimize the resources of Saint Martin. The current infrastructures must be expanded and upgraded on this island following the smart city criterion. Secondly, the wave energy converter (WEC) can extract a significant portion of energy for microgrid integration from the Bay of Bengal. A techno-economic analysis compares five WECs: eco wave power, wavestar, oscillating surge, submerged point absorber, and pelamis. Eco wave power has been identified as a viable and cost-effective technology. Thirdly, HOMER software optimizes six distinct microgrid topologies, comprising of ground PV (GPV), floating PV (FPV), wind turbine generator (WTG), bio-diesel generator (BDG), eco wave power (EWP), bidirectional converter (BDC), first life battery (FLB), second life battery (SLB), and supercapacitor (SC). The GPV/FPV/WTG/EWP/BDG/BDC/SLB hybrid architecture reveals most favorable configuration addressing Sustainable Development Goal 7. Finally, PSCAD/EMTDC tools performs both the steady-state and transient analysis of microgrids. Simulation results show that the GPV/FPV/WTG/EWP/BDG/BDC/SC design outperforms. The study outlines the benefits of employing eco wave power and second life batteries, as well as the advantages of using a supercapacitor as a speedy responder to disturbances. Overall, the work provides policymakers the multidisciplinary expertise for transitioning a small island towards a tourist-intensive smart city using local energy resources while also ensuring decent lifestyle for islanders. |
