Article
Full-text available
In this paper, shunt active power filter (SAPF) is designed to address the problem of current harmonics in the source current arising from a nonlinear load and improve the quality of electric power. That will be by compensating reactive power and harmonic currents. The PI controller responsible for DC-link energy storage tuning was developed using...

This paper presented a smartness 2-D lookup table (2-DLT) control by means of adaptation gain to develop a frequency controller and facilitate the power-sharing requirements in an isolated micro-grid system. This intelligence of an expert controller adopts the scale of adaptation gain for estimating control design. Synchronous power generators are...

Full-text available
In recent years, electronic transformers and electronic devices (nonlinear loads) have increased. These loads are the source of harmonics (non-sinusoidal and distorted waves) and the interactive force that affects the performance of the power system network. Also, it badly affects the power factor and electrical energy on the scales of efficiency a...
Article
Full-text available
Modern power systems are complex and non-linear and their operating can vary over a wide range. This paper presents a linear mathematical model of the synchronous generator to control the excitation system based on Neural Network to simulate an Automatic Voltage Regulator. The voltage regulator is used to modify terminal voltage for the purpose of...
Conference Paper
Full-text available
The frequency and power generation control in a power system is usually referred to as a load frequency control. This paper focuses on two control schemes based on the adaptive controller to track sudden load increase and smooth the transfer from grid-connected to island mode and improving the performance of hybrid micro-grid. One scheme uses a mod...
Article
Full-text available
The excessive waveform distortions in the present power distribution systems are produced mainly by the large number of non-linear loads. Such distributed sources of harmonics cannot be easily treated by the traditional mitigation methods. Furthermore, classical control theory suffers from some limitations due to the nature of the controlled system...
Research
Full-text available
Non-linear loads draw harmonic non-sinusoidal currents and voltages in the connection point with the utility and distribute them through it. A shunt active power filters has been proposed as an effective tool for improving power quality and reactive power compensation. The simulated system is a three phase balanced voltage system with nonlinear loa...

This paper presents a method for obtaining the desired reference current for Voltage Source Converter (VSC) of the Shunt Active Power Filter (SAPF) using Synchronous Reference Frame Theory. The method relies on the performance of the Proportional-Integral (PI) controller for obtaining the best control performance of the SAPF using Particle Swarm Op...
Preprint
The increase of the harmonics disturbance in the ac mains currents has become a major concern due to the wide spread of power electronics equipment in modern electrical systems. This paper presents the analysis and simulation of a three-phase active power filter (APF) compensating the harmonics and reactive power created by nonlinear in steady stat...

This paper intends to present the recent development of artificial intelligence (AI) applications in active power filter (APF). As a result of the development in power electronic technology, (APF) continues to attract ample attention. Compared with the traditional reactive LC filter, active power filter is considered to be more effective in compens...

The aim of this paper is to reduce the cost of supplying electricity in remote area and to get optimal operation of the distribution network including renewable energy sources. In actual power system operations, the load is changing continuously and randomly, as the ability of the generation to track the changing load is limited due to physical/tec...
