PROJECT TITLE :
Damped-SOGI Based Control Algorithm For Solar PV Power Generating System - 2017
This paper deals with two-stage solar photovoltaic (PV) system with a damped-second-order generalized integrator (SOGI) algorithm. Proposed topology not solely integrates the PV energy to the grid, in addition, it provides the load compensation, power issue correction, and harmonics elimination. Therefore, a double stage system is proposed where the primary stage is a dc–dc boost converter, which performs the utmost power point tracking by regulating its duty ratio. For extracting most power from the PV array, an incremental conductance-based mostly approach is utilized. Moreover, in the next stage, a voltage source converter (VSC) is utilized. To regulate the VSC, a damped-SOGI algorithm is employed. By employing a damped-SOGI-primarily based control algorithm, elementary active elements of load currents are extracted for evaluating the reference grid currents. After comparing reference grid currents with sensed grid currents, switching pulses for the grid tied VSC are created. A prototype of the proposed system is developed within the laboratory and take a look at results are presented for verification of control of solar photovoltaic system.
