The quality of the power electric is characterized by the measurement and the analysis of the
electric disturbances which make it possible to understand the origin of the disturbances, to …

Power quality (PQ) of power operating device is one of today's most discussed topic but also
it is a most problematic subject in recent years. The increasing application of power …

UPQC is the powerful tool to settle the power quality problems. UPQC consist of combined
series, active power filter (SAPF) that compensates voltage harmonics, voltage sags and …

Microgrid technology makes possible coordination and effective use of different energy
resources for supplying loads. In order to have synchronous operation between inverter …

In this paper, the main goal is to improve the UPQC functioning against the frequency
variation, through a good parameters selection of the connection passive filters. Indeed, an …

Distributed generation (DG) such as solar and wind systems have attracted energy sectors
as an alternative sources to produce electrical energy either in grid-connected or islanding …

In this paper the design of combined operation of UPQC and PV-ARRAY is proposed. The
proposed system is composed of series and shunt inverters connected back to back by a …

As the environmental conditions (temperature, irradiance) vary the power output of a solar
system differs which in turn reduces the efficiency of the system. This paper shows Maximum …

In this paper, an artificial bee's colony (ABC) algorithm based neuro fuzzy controller (NFC)
will be proposed for improving the performance of UPQC. Here, the error and change of …

A qualidade de energia elétrica (QEE) tem sido um aspeto da rede elétrica que ganha cada
vez mais importância, tanto na investigação académica como no desenvolvimento de …
