Power system oscillation damping controller design: a novel approach of integrated HHO-PSO algorithm
As the installed capacity of wind power increases across the world, its impact on power systems is becoming more important. To ensure the reliable operation of a power system which is significantly fed by wind power, the dynamics of the system must be understood. The purpose of this study is to analyse the dynamic impact of large-scale wind farms on the stability of a power grid, and to investi...
Analysis of Nonlinear Characteristics of Turbine Governor and Its Impact on Power System Oscillation
<span lang="EN-US">Many international organizations have called for reducing usage of renewable energy as a means to reduce carbon dioxide emissions, this paper studies the case electricity production based fossil fuels. Currently existing solutions is shift from fuels clean energy. Electrical interconnections are used between large-scale areas; these major problem that phenomenon oscilla...
Visual cortex (V1) exhibits two types of gamma oscillation: a well-characterized broadband (30-90Hz) rhythm, and a narrowband oscillation occurring at frequencies close to 60 Hz in mice. We investigated the source of narrowband gamma, the factors modulating its strength, and its relationship to broadband gamma. Narrowband and broadband gamma power were uncorrelated. Increasing visual contrast h...
This paper presents the robust design of a Power System Stabilizer (PSS) to improve the stability in the composed two-area Load Frequency Control (LFC) and Automatic Voltage Regulator (AVR) using Artificial Bee Colony (ABC) in a restructured environment. The coupling effects of the LFC and AVR loops are studied by extending the linearized Automatic Generation Control (AGC) system to include the...
Abstract: In order to harvest photovoltaic energy efficiently, several methods exist, yet most of them failed to address the issues related to extract the maximum power under rapidly changing solar irradiance conditions. In conventional incremental conductance, large step size reduces tracking time but oscillation remains around maximum power point (MPP). However, small step size reduces the os...
