A New Reference Waveform Estimation Strategy for Unified Power Quality Conditioner (UPQC(
In this paper, a new reference waveform estimation
strategy based on an adaptive notch filter (ANF) is proposed
for unified power quality conditioner (UPQC). Two coupled
ANFs are used to generate the reference waveforms...
Inverse Unified Power Quality Conditioner: Investigations towards its Performance and Capabilities
The cost of switching devices increases
exponentially by increasing their rating. Hence,
attractiveness of using unified power quality conditioners
(UPQC) is reduced when compensation to be carried out for
high power...

Power Quality-friendly Active Islanding Detection for Photovoltaic Distributed Generation
in case of any fault which leads to losing
the support of the main utility system. Active islanding detection methods (IDMs) are more
reliable than passive ones but they cause power quality issues. Harmonic current injection as an...
A New Synchronous Reference Frame-Based Method for Single-Phase Shunt Active Power Filters
This paper discusses the design of a novel synchronous reference frame (SRF) method that can extract the reference compensating current for single-phase shunt active power filters (APFs). Unlike previous SRF studies, the ...

Recursive Algebraic Method of Computing Power System Harmonics
Ensuring power quality in power systems demands fast calculation of harmonics. In this paper, a recursive algebraic approach
to the calculation of current transformer (CT)-derived current signal frequency and harmonics is proposed...
