This article derives a new explicit expression of current of a double-diode model (DDM) photovoltaic (PV) module from the implicit current-voltage (I-V) expression. Here, the exponential term of the I-V expression of a DDM PV module is represented by Taylor series. The validation is done on the implicit I-V expression with the derived quartic I-V e...
Partial shading in photovoltaic (PV) array causes mismatch loss and reduces power output. To dilute the concentration of partial shading effect on the array, a novel module relocation technique (MRT) is proposed to improve the power output of the partially shaded PV array. In this proposed technique, the physical position of the modules in totally...
To meet the exponentially growing demand for clean and green energy, the solar photovoltaic (PV) system’s importance is increasing day by day, for which PV modeling is considered to be one of the most important work in the current state-of-the-art methods. To effectively model a PV system, accurate PV parameter estimation is of the utmost importanc...
In the existing solar photovoltaic modules, cells are connected in series. The performance of the series-connected module degrades severely during partial shading condition. Further, the use of bypass diode causes multiple peak (local and global peaks) problem. Therefore, total cross tied (TCT) connection has been proposed in this paper to connect...
In this paper, the maximum power point (MPP) of a photovoltaic (PV) source is estimated using the proposed explicit current-voltage (I- V) expression. The conversion of implicit expression of current to explicit expression of I-V equation is carried out using Maclaurin series expansion. The explicit I-V function of the PV module is validated with t...
This paper presents a novel approach for the conversion of an implicit current-voltage (I-V) expression of a double diode model (DDM) photovoltaic (PV) module to an explicit expression of current in terms of voltage. A new method is proposed for the estimation of maximum power point (MPP) of a DDM PV module using the explicit I-V expression of a PV...
