High Performance Model Preditive Technique For Mpptgrid-Tied Pv System Using Chopper

  Vimala.M,  Dr.C.B.Venkataramanam

In this paper a single-stage grid-tied MPPT used for extracting the maximum available power and feeding the power to the grid. The proposed technique predicts the future behavior of the photovoltaic side voltage and current by using a digital observer which estimates the parameters of the photovoltaic module. The proposed method features simultaneously reduction in oscillation around maximum power point (MPP) and fast convergence by adaptively changing the perturbation size using the predicted model of the system. The experimental results demonstrate fast tracking response under dynamic weather condition, small steady state error, small oscillation around MPP at steady state, and high MPPT efficacy for wide range of solar irradiance levels. DC–DC converter for stand-alone power systems is proposed to integrate solar and battery power. In the proposed topology, two coupled inductors are employed as voltage gain extension cells for high voltage output applications. Two sets of buck–boost type active-clamp circuits are used to recycle the energy stored in the leakage inductors and improve the efficiency
