CONTROL OF DISTRIBUTED GENERATORS AND DIRECT HARMONIC VOLTAGE CONTROLLED ACTIVE POWER FILTERS FOR ACCURATE CURRENT SHARING AND POWER QUALITY IMPROVEMENT IN ISLANDED MICROGRIDS

Harmonics are regarded as one of the main challenges in a microgrid.This issue may even get worse when different distributed generators (DGs) work together to solve the load sharing problems due to mismatched feeder impedances and diversified DG ratings.Even though load sharing can be achieved, the microgrid suffers from voltage unbalance and total

We performed pentair hose this study to develop a reliable method for inducing colitis in rats using 2,4,6-trinitrobenzene sulfonic acid (TNBS) to reduce the variation in ulcer size.A pair of ring forceps was used to clamp the colon and 0.1 M TNBS in ethanol was injected into the luminal side of the clamped portion.This method resulted in rawafrica

Optical microscopy is a vital tool for read more visualizing the cellular and sub-cellular structures of biological specimens.However, due to its limited penetration depth, its biological applicability has been hindered.The scattering and absorption of light by a wide array of biomolecules causes signal attenuation and restricted imaging depth in t
