An attempt has been made in this paper to solve the non-linear and ill-posed Electrical Impedance Tomography (EIT) inverse problem using clustering-based particle swam optimization (PSO). To enhance optimal search capability in such an ultra high dimension space and improve the quality of the reconstructed image, an adaptive PSO algorithm combined with a modified Newton–Raphson algorithm and a ...

There is a substantial body of ongoing research improving the Blade Element Momentum (BEM) theory and applying it to the optimization of wind turbine rotors. Both of these developments challenge the suitability of fixed point iteration schemes being applied to advanced BEM models. This article explores the mathematical behavior of the BEM equations, with special attention to the application of ...

Contingency analysis plays an important role in assessing the static security of a network. Its purpose is to check whether system can operate safely when some elements are out service. In real-time application, computational time required perform calculation paramount for operators take immediate actions prevent cascading outages. Therefore, numerical performance contingency main focus this cu...

<p>Distributed generations (DG), specially including renewable sources such as wind and sun are offering several opportunities for the currently in existence distribution networks becoming one of keys treatment its problems. Knowing effects each kind DG on is a primordial task because impacts differ from to another. In this paper, we have analyzed compared two kinds DG, which provides rea...

A new approach for distributed power load flow calculation using nonlinear equations is presented. This new approach, which is similar to the Newton Raphson’s simple method, uses an inverse Jacobian matrix of initial states for the iteration process. Moreover, nonlinear quadratic equations have been used as they are more appropriate for the distributed power load flow calculation. This paper de...

This paper describes simple implementation of homotopy (also called continuation) algorithm for determining the proper resistance of the resistor to dissipate energy at a specified rate of an electric circuit. Homotopy algorithm can be considered as a developing of the classical methods in numerical computing such as Newton-Raphson and fixed point methods. In homoptopy methods, an embedding par...
