A Novel Approach for Direct MPP Estimation of a PV Module Under Different Irradiation Conditions

IEEE transactions on energy conversion, 2021
In this article, 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

Power series expansion, decreasing property, and concavity related to logarithm of normalized tail of power series expansion of cosine

Electronic Research Archive
In this paper, in view of a determinantal formula for higher order derivatives of the ratio of two differentiable functions, we expand the logarithm of the normalized tail of the power series expansion of the cosine function into a Maclaurin power series

Power series expansion and decreasing property related to normalized remainders of power series expansion of sine

Filomat
In the paper, with the aid of a derivative formula for the ratio of two differentiable functions, in view of a monotonicity rule for the ratio of two differentiable functions, in terms of the Hessenberg determinants, the authors present a Maclaurin power

Monotonicity results of ratio between two normalized remainders of Maclaurin series expansion for square of tangent function

Mathematica Slovaca
In the paper, in view of the monotonicity rule for the ratio between two Maclaurin power series and by virtue of establishment of a monotonicity result for a sequence involving the ratio between two Bernoulli numbers, the authors investigate the ...

Expansion of Elemetnary Functions into a Power Series Using Algebraic Methods

In the world of mathematics
As is well known, power series-based methods are one of the pillars of mathematical analysis. For analytic functions, the power series can be easily obtained from Taylor's theorem in the form of Maclaurin series by calculating the derivatives of these ...

Some results for the family of holomorphic functions associated with the Babalola operator and combination binomial series

AIMS Mathematics
In this paper, we define a new class $ \mathcal{R}_{t, \delta, \upsilon }^{m, n, \sigma }\left(\mathcal{A}, \mathcal{B}\right) $ of holomorphic functions in the open unit disk defined connected with the combination binomial series and Babalola operator ...

An Improved Large-Signal Model for Accurate Transient Analysis of DDV-PLL Under Large Grid Disturbance Conditions

IEEE transactions on power electronics
To against the variation of grid voltage amplitude, directly dividing the d-axis voltage phase-locked loop (DDV-PLL) is widely used due to its simple structure. However, conventional DDV-PLL models fail to describe the transient behavior under large grid
