Increasing wind generation insertion levels on electrical grids through power converters may cause instabilities in the AC grid due to intermittent nature. Integrating a Battery Electric Energy Storage System (BESS) can smooth injection at Common Coupling Point (PCC), contributing system voltage and frequency stability. In this article, it is proposed analyze operation of lithium-ion battery te...

An electric arc furnace (EAF) is known as nonlinear and time variant load that causes power quality (PQ) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. One of the most important problems to study the EAF behavior is the choice of a suitable model for this load. Hence, in this paper, a probabilistic three-phase model is proposed base...

This project proposes a new AC-DC bridgeless CUK rectifier. The new bridgeless single-phase AC–DC power factor correction (PFC) rectifiers based on CUK topology are proposed. The absence of an input diode bridge and the presence of only two semiconductor switches in the current flowing path during each interval of the switching cycle result in less conduction losses compared to the conventional...

factor  is introduced for direct head loss calculation and sizing in dual-diameter laterals of sprinkler and trickle irrigation systems when the hazen-williams equation is to be applied. application of this factor prevents trial and error and uses fewer head-loss equations in calculating the total friction loss and designing dual-diameter laterals. the proposed factor is a function of total num...
