A single-phase 9-level cascaded multilevel inverter with SHE PWM, and battery balanced discharge functions is presented in this paper. Each H-bridge is connected to separate DC source and produce different voltage levels −Vdc, 0, +Vdc. Each cell voltage will differ apart over time. So always switch on the battery with highest voltage that is in descending manner. Then the discharging time is dramatically...
This paper aims to develop a new model for hybrid power system (HPS) in smart premises to study economic effect of HPS for various ratings. Photovoltaic (PV) modules and wind mill with lead acid tubular battery as storage device are taken as HPS for the study. Wind speed, solar irradiation and cell temperature for one year with one hour duration are fed in to HPS model. The maximum and minimum ratings...
