Design and Simulation Grid-Connected Photovoltaic Power System

A grid-connected electrical phenomenon (PV) power grid with high voltage gain is projected, and also the steady-state model analysis and also the management strategy of the system are given during this paper. For a typical PV array, the output voltage is comparatively low, and a high voltage gain is obligatory to comprehend the grid-connected perform. The projected PV system employs a ZVT-interleaved boost convertor with winding-coupled inductors and active-clamp circuits because the 1st power-processing stage, which may boost an occasional voltage of the PV array up to a high dc-bus voltage. 2 compensation units are side to perform within the system management loops to attain the low total harmonic distortion and quick dynamic response of the output current. what is more, an easy maximum-power-point-tracking technique supported power balance is applied within the PV system to cut back the system complexness and value with a high performance. At last, a 2-kW epitome has been engineered and tested to verify the theoretical analysis of the paper.
