MATLAB Based Modelling and Performance Study of Series Connected SPVA under Partial Shaded Conditions

Abstract: In a solar photovoltaic array (SPVA) spread over vast area, it is likely that shadow may fall over some of its cells due to tree leaves falling over it, birds or bird litters on the array, shade of a neighboring construction, passing clouds etc. Under partial shaded conditions the PV characteristics get more complex with multiple peaks. It is important to understand and predict them to get maximum possible power from the SPVA. This paper presents a MATLAB-based modelling and simulation scheme suitable for studying the characteristics of a series connected SPVA under partial shaded conditions. The conventional model is modified to include the effect of shading in the SPV module parameters for simulation study. The simulation of MPPT algorithm to track the global maximum is also presented. The model is practically validated using electronic load.

Swarm intelligence based optimisation in thermal image fusion using dual tree discrete wavelet transform

Abstract: In this paper, we propose a particle swarm optimised image fusion framework in Discrete Wavelet Transform domain (DWT) that combines the thermal image with the visual image to obtain a single informative fused image. Dual tree Discrete Wavelet Transform (DT-DWT) is applied for feature selection and Particle Swarm Optimisation technique is used to obtain the optimised image. In the fusion process, an optimised weighting factor has been used to construct a new composite image with maximum entropy and minimum Root Mean Square Error. We investigate the fusion performance of the proposed fusion algorithm with distorted input images by adding Gaussian white noise and blurring. The fusion results are compared with existing multi-resolution based fusion techniques such as Laplacian Pyramid, Gradient Pyramid, Ratio of Laplacian Pyramid and Shift Invariant Discrete Wavelet Transform. The quality of the fused image is assessed using seven quality metrics and the results indicate that our proposed method outp...
