Wind power parallel operation is an effective way to realize the large scale use of wind power, but the fluctuations of power output from wind power units may have great influence on power quality, hence a new method of power smoothing and capacity optimized allocation based on hybrid energy storage technology is proposed in terms of the uncontrollable and unexpected characteristics of wind spe...

Abstract This paper analyzes the power smoothing of grid-connected photovoltaic (PV) systems under fast irradiance changes. The analyzed converter is composed a triple active bridge series-resonant (TABSR) DC-DC cascaded with voltage source inverter (VSI). Two controlled variables are considered: battery current and PV voltage. TABSR modeled as sources for ports. ramp rate (RR) control algorith...

The main objective of this work was to determine the worth installing an electrical battery in order reduce peak power consumption. importance question resides expensive terms energy bills when using maximum level. If consumption decreases, it affects not only revenues level bills, but also results important reductions at source power. This way, transformer and other elements can be removed fro...

We examine a test of a nonparametric regression function based on penalized spline smoothing. We show that, similarly to a penalized spline estimator, the asymptotic power of the penalized spline test falls into a small- K or a large-K scenarios characterized by the number of knots K and the smoothing parameter. However, the optimal rate of K and the smoothing parameter maximizing power for tes...

A methodology is introduced for smoothing the Complex Transfer Function of measured responses using well-established or arbitrary fractional octave profiles, based on a novel time-frequency, mapping framework. A corresponding impulse response is also analytically derived having reduced complexity but conforming to perceptual principles. The relationship between the Complex Smoothing and the tra...

Wind energy is one of the most common types of renewable energy resource. Due to its sustainability and environmental benefits, it is an emerging source for electric power generation. Rapid and random changes of wind speed makes it an irregular and inconsistent power source when connected to the grid, causing different technical problems in protection, power quality and generation dispatch cont...
