Damped-SOGI Based Control Algorithm For Solar PV Power Generating System - 2017

ABSTRACT:

This paper deals with 2-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, additionally, it provides the load compensation, power issue correction, and harmonics elimination. Therefore, a double stage system is proposed where the primary stage could be a dc–dc boost converter, which performs the most power purpose tracking by regulating its duty ratio. For extracting most power from the PV array, an incremental conductance-based approach is used. Moreover, in the next stage, a voltage supply converter (VSC) is used. To control the VSC, a damped-SOGI algorithm is employed. By employing a damped-SOGI-based mostly management algorithm, basic active components of load currents are extracted for evaluating the reference grid currents. When 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 in the laboratory and take a look at results are presented for verification of management of solar photovoltaic system.
