TL;DR: In this article, a microprocessor-controlled tracker capable of online voltage and current measurements and programmed with both voltage-based and current-based MPPT algorithms is constructed, where the load of the solar system is either a water pump or a resistance.

TL;DR: This paper presents a perspective on power quality issues through railway electrification development and investigates the necessity of power quality and system requirements for appropriate power quality.

TL;DR: In this paper, the effects of nonsinusoidal voltages and currents on the performance of static under-frequency and overcurrent relays are experimentally studied, in such a way that the frequency, amplitude and phase shift of individual harmonics could be adjusted in a controlled manner by using a waveform generator with a phase-locking circuit.

TL;DR: In this article, a GA-based approach for simultaneous power quality improvement and optimal placement and sizing of fixed capacitor banks in radial distribution networks in the presence of voltage and current harmonics is presented.

TL;DR: In this article, a fuzzy-based approach for optimal placement and sizing of fixed capacitor banks in radial distribution networks in the presence of voltage and current harmonics is presented, where a suitable combination of objective function and constraints is generated as a criterion to select the most suitable bus for capacitor placement.
