One of the maximum popular renewable electricity assets is photovoltaics. Grid-connected photovoltaic structures are designed to generate as a lot strength as possible. Photovoltaic systems have nonlinear traits imposed with the aid of environmental factors consisting of radiation and temperature, making it hard to operate at the most power factor. It may additionally be tough to extract the maximum amount of electricity due to the formation of nearby maxima because of other factors which include shading or degradation. There are several MPPT algorithms and approaches that may be used for this. Publications with comparative analyses have also been released. However, in most of these works, comparisons are based on simulations or literature review. From the simplest to the most complex MPPT methods, empirical validation remains important. The two simplest and most widely used MPPT techniques are the perturbation, open-loop, and incremental conductance algorithms. The three most challenging ones are sliding mode control, backstepping controller, and particle swarm optimization. Therefore, five MPPT algorithms are empirically studied in this paper. Under test settings, Matlab/Simulink was used to conduct experimental experiments. The findings demonstrate that under ordinary operating circumstances, the backstepping algorithm is the only one capable of finding the global MPP under the influence of local shadowing.

“…Proportional-integral controllers have the merits of easy design as well as structural simplicity. Many literatures have been reported regarding the control of solar energy system [3][4][5][6][7][8][9][10][11][12][13][14][15]. However, solar energy systems governed by proportional-integral controllers may be affected with uncertainties, like partial shading problem.…”

Proportional-integral (PI) controller with simple architecture as well as convenient design makes it widely adopted in the control of solar energy systems. Due to partial shading as well as fault influence, the solar panels tend to be trapped at regional extremely values, attenuating the dynamic and steady-state response. For the sake of strengthening the system control effectiveness, this paper employs a grey prediction-based PI controller to attain a global maximization of the wattage pointed following in sun power plate, providing a pure sine waveform with lower percentage of total harmonic distortion, in addition to fast transience of the solar energy system output voltage. The PI performs tracking control and simultaneously the grey prediction uses a logistic grey model to accurately predict the system state as well as to adjust the PI control parameters for establishing robust system response. The results reveal that the output of the solar system can produce fast dynamics and high efficient steady-state performance, thereby supporting the theoretical validity.
