8Partial shading conditions (PSCs) in Photovoltaic (PV) system is an inevasible situation which 9 curtails the PV array output by exhibiting multiple peaks in its Power-Voltage (P-V) curve. The 10 multiple peaks consist of a single global maximum power point (GMPP) and many local maximum 11 power points (LMPP). The presence of multiple peaks makes tracking of maximum power point 12 more difficult and demands an efficient controller to track the global peak of the P-V curve. 13In the present work, a novel intelligent asymmetrical Fuzzy Logic Control (AFLC) based maximum 14 power point tracking (MPPT) algorithm has been proposed for tracking GMPP. The fuzzy 15 membership functions of the proposed algorithm have been optimized using a heuristic approach. 16The algorithm has been designed, developed and analyzed using MATLAB/Simulink. Furthermore, 17to establish the superiority of proposed AFLC algorithm, it has been compared with conventional 18perturb & observe (P&O) algorithm and intelligent Fuzzy Logic Control (FLC) based algorithm for 19GMPP tracking and shading losses under standard test condition (STC) and partially shaded 20 conditions. 21 [24] Kumar P. and Mahajan A.

The modal analysis, which decouples the contact wire and rail track conductors, is used to develop an integrated model of single rail track and contact wire. The characteristic impedance and propagation constant matrices of integrated model have been computed. The authors have studied effects of various parameters of interest on characteristic impedance and propagation constant using sensitivity analysis. The sensitivity functions of series impedance and shunt admittance related to contact wire and catenary have been developed and validated in this paper.
