In an attempt to widen the prospects for clean energy utilization and sustainable
development, wind and solar power are considered as the prime contributors. But, their …

The fast growth of the world's energy demand in the modernized world has stirred many
countries around the globe to focus on power generation by abundantly available …

Optimal power flow (OPF) is a highly non-linear complex optimization problem where the
steady state parameters of an electrical network need to be determined for its economical …

This paper presents an adaptive group search optimization (AGSO) algorithm for solving
optimal power flow (OPF) problem. In this study, different aspects of the OPF problem are …

In this work the variability of WP (wind power) has been suitably modelled and incorporated
with the thermal generating units. The goal is to operate the wind-thermal generation system …

Considering the importance of clean energy, the combined operation of hydro-thermal-wind
(HTW) system is formulated in optimal power flow (OPF) framework. The objective is to find …

Most of the practical engineering optimization problems are highly nonlinear, nonconvex,
and sometimes discontinuous. Classical optimization techniques, mostly being differential …

A fragile, block-wise, and content-based watermarking for image authentication and
recovery is presented. In this scheme, the watermark of each block is an encrypted form of its …

Maximum loadability limit (MLL) is a realistic index to evaluate the steady state voltage
stability because it provides system operator a better practical sense of security margin in …

A new evolutionary hybrid algorithm (HA) has been proposed in this work for environmental
optimal power flow (EOPF) problem. The EOPF problem has been formulated in a nonlinear …
