Wind Farms (WF) employing squirrel cage induction generator (SCIG) is directly connected to the grid, it represent a large percentage of the wind energy conversion systems around the world. In facilities with moderated power generation, the WF are connected through Medium Voltage (MV) distribution headlines. A situation commonly found in such scheme is that the power generated is similar to the...

ABSTRACT This paper presents a system that provides photovoltaic generation as well as the functions of a unified power quality conditioner (UPQC). The system can be controlled for current harmonics and reactive power compensation simultaneously by using a converter operating as active shunt filter. The other converter is used as active series filter and it compensates voltage harmonics or volt...

With an increase of non-linear load in today’s electrical power systems, the rate quality drops and voltage source frequency deteriorate if not properly compensated with appropriate device. Filters are most common techniques that employed to overcome this problem improving quality. In paper improved optimization technique filter applies system is based on a particle swarm using artificial neura...

The current paper presents a novel control strategy of a three-phase, four-wire Unified Power Quality (UPQC) to improve power quality. The UPQC is realized by the integration of series and shunt active power filters (APF) sharing a common dc bus capacitor. The realization of shunt APF is carried out using a three-phase, four-leg Voltage Source Inverter (VSI), and the series APF is realized usin...

This article offers a power quality (PQ) strategy to reduce light intensity flickers, voltage enhancements, and harmonics mitigation of the grid current in extensive networks LED lighting at Cairo airport, Egypt. A transformerless unified conditioner (TL-UPQC) with its controls is presented address majority PQ issues network. The TL-UPQC comprises dynamic restorer (DVR) as series compensator, w...
