in my energy systems class, a technical elective taken by mechanical engineering students.The course is basically an applied thermodynamics class, covering conventional andunconventional power and refrigeration systems. Over the course of two class periods, I derivedthe equation resulting in the “Hubbert curve,” and then had students use it to model theproduction rates of various fossil fuels, predicting the years of peak production rate anddepletion.The exponential modelThe exponential model assumes that the instantaneous rate of production is proportional to thecumulative production, Q: dQ ? aQ (1

The high and low voltage balancing operation across the DC bus capacitor hasbeen very challenging for SST configuration especially for parallel-connected DAB and multi-port application [15]. In this paper, a d-q vector control-based DC voltage and load voltagebalancing technique for both rectifier and inverter stages are presented. A simple classic d-qvector controller is applied in this system.Rectifier StageThe high voltage grid is connected to the front end of the SST that is
