VOLTAGE STABLIZATION OF SOLAR POWERED DC MICROGRID

Keeping voltage in a circuit relatively close to the desired value is very important. In this paper, we study voltage regulation for a dc microgrid. This microgrid consists of a Photo Voltaic panel, battery source, constant resistance and power loads. A dynamic model of dc microgrid is developed. Based on this dynamic model, we design a local state feedback controller with MOSFETs which will regulate voltage to the desired set points and will maximize PV output. This is designed using output regulation theory. Simulations are done to investigate the effectiveness of the proposed control scheme.
