Design of PV Based Stand-Alone System for DC Microgrid

Abstract

Renewable energy sources have a significant impact on reducing the burden of the human being on the dependence on fossil fuel for its energy consumption. There are different renewable energy sources which are exploited in recent years. One of the widely used renewable energy source is solar energy. With the help of photovoltaic panel, electricity is generated which is dependent on solar irradiance and ambient temperature. Maximum Power Point Tracking (MPPT) is used to take maximum power from the Photovoltaic (PV) panel in varying environmental conditions. This thesis provides an detailed design and implementation aspect of a DC-micro grid using PV module. perturb & observe maximum power point tracking algorithm is used to track the maximum power point, for the requirement of MPPT a data acquisition (DAQ) unit is made up to sense the PV panel output voltage and current. A output of PV panel is given to boost converter to provide a regulated voltage to the load. The mathematical model of PV panel, MPPT and required power electronic converters are simulated and the simulation results are experimentally validated.
