Design and Analysis of Charging Stations for Battery Electric Bus with PV, Wind Turbine, and PLN Grid

Along with the increasing need for transportation, the more congestion on the roads and carbon gas emissions are also increasingly difficult to prevent. Reducing carbon emissions is one of the main goals of governments in the world to tackle climate change. Electric vehicles as public transportation also began to be developed. However, there is an innovation, namely turning it into a larger vehicle, one of which is like an electric bus. This project is expected to design a hybrid charging station from photovoltaic and wind turbine and analyze its performance. BEB Charging Station requires a stable power input for round-the-clock operation with renewable energy to create stable power such as solar energy and wind energy and coupled with a supply from the PLN Grid. In this study, we will study the design of a hybrid charging station with an EBT source which will later be controlled by EMS. The system performance will be designed and tested using MATLAB 2021b, especially Simulink. The simulation results show that the EMS control can produce maximum power generated by photovoltaic and wind turbines. But for better results, it is necessary to make the power sensor range and duty cycle more. In terms of power stability, PV, Wind, and Grid PLN can meet the required battery power with the addition of SOC every second by 0.00674%.
