A review of active filters for power quality improvement
TLDR
This paper presents a comprehensive review of active filter configurations, control strategies, selection of components, other related economic and technical considerations, and their selection for specific applications.Abstract:
Active filtering of electric power has now become a mature technology for harmonic and reactive power compensation in two-wire (single phase), three-wire (three phase without neutral), and four-wire (three phase with neutral) AC power networks with nonlinear loads. This paper presents a comprehensive review of active filter (AF) configurations, control strategies, selection of components, other related economic and technical considerations, and their selection for specific applications. It is aimed at providing a broad perspective on the status of AF technology to researchers and application engineers dealing with power quality issues. A list of more than 200 research publications on the subject is also appended for a quick reference.read more

Instantaneous Reactive Power Compensators Comprising Switching Devices without Energy Storage Components
TL;DR: In this paper, a new instantaneous reactive power compensator comprising switching devices is proposed, which requires practically no energy storage components, and is based on the instantaneous value concept for arbitrary voltage and current waveforms.
Vector analysis and control of advanced static VAr compensators
TL;DR: The advanced static VAr compensator (ASVC) as mentioned in this paper is based on the principle that a self-commutating static inverter can be connected between three-phase AC power lines and an energy storage device, such as an inductor or capacitor, and controlled to draw mainly reactive current from the lines.
