In order to minimize losses in the distribution network, integrating non-conventional energy sources such as wind, tidal, solar, and so on, into grid has been proposed many papers a viable solution. Using electronic power equipment control nonlinear loads impacts quality of power. The unified conditioner (UPQC) is FACTS device with back-to-back converters that are coupled together DC-link capac...

Nowadays, integration of renewable sources into the local distribution system and nonlinear behavior advanced power electronic equipment have made a large impact on quality (PQ). The unified conditioner (UPQC) is multifunctional FACTS device, which combination both shunt active filter series filters via common DC link. Presently, artificial intelligence playing vital role in development intelli...

Unified power quality conditioners (UPQCs) allow the mitigation of voltage and current disturbances that could affect sensitive electrical loads while compensating the load reactive power. Diverse control techniques have been proposed to evaluate the instantaneous output voltage of the series active power filter of the UPQC but, in most cases, these controllers only can compensate a kind of vol...

This paper describes the problem of voltage sags and swells and its severe impact on sensitive loads and introduces a new solution for doubly fed induction generators to stay connected to the grid during voltage sags. The main idea is to increase the stator voltage to a level that creates the required flux to keep the rotor side converter current below its transient rating. To accomplish this g...

The typical loads in the commercial buildings comprise of many single phase and three phase loads which includes non-linear loads. These loads are highly sensitive for any input variations in voltage. The performance of the electrical equipment gets worsened if they are supplied with polluted or distorted voltage. This paper presents modeling and analysis of custom power devices. SAPF based UPQ...

Power Quality (PQ) parameters such as voltage RMS value, Total Harmonic Distortion (THD), and Power Factor (PF) are main topics to be considered in the connection of sensitive loads to the grid. In this paper, a Unified Power Quality Conditioner (UPQC) based on an Indirect Matrix Converter (IMC) is proposed to address some PQ issues as mitigation of voltage harmonics and compensation of sags an...
