Solar Pv System

In this project, a new system for power supply for remote areas has been proposed. In the proposed system, solar PV based system with battery storage for stand-along application has been discussed. In addition, the use of a multilevel inverter and high-gain DC/DC converter has been proposed. The proposed multilevel inverter generates a nine-level output voltage waveform with quadruple voltage gain. The proposed DC/DC converter is based on the concept of a switched-inductor with voltage lift switched-capacitor and has been verified for a voltage gain of 20. The experimental results confirmation the satisfactory performance for stand-alone applications of the proposed converters.

In this work, a new modular multilevel inverter topology is introduced for a single phase grid connected Photovoltaic system. This multilevel inverter use less number of switches to generate seven levels compared to other conventional multilevel inverters. This requires only one isolated dc source to operate. So it is suitable for renewable energy application. This inverter is designed by submodule configuration; each sub module contains two switches and one DC link capacitor. The sub modules will be added to the inverter depending on number of levels. The voltage balancing of DC link capacitor is carried out by Y matrix PWM technique. Because of Y matrix PWM technique, the inverter gets a self capacitor voltage balancing ability. So there is no need of external devices required for balancing the voltage of capacitor. A PLL for grid integration and LCL filter are designed and integrated with this inverter. The simulation of proposed system is carried out by MATLAB/SIMULINK and performance of THD is monitored as per standards
