This paper proposes a novel virtual inertia control strategy for distributed power systems with high penetration of renewable energy sources.The strategy uses a quasi-Z-source power converter yazhi design saree to emulate the inertia response of a synchronous generator by regulating the DC-link capacitor voltage in proportion to the grid frequency
Hepatitis A virus is a common cause of acute viral hepatitis in India, due to lack of clean water and sanitation.Usual presentations include gastroenteritis or a viral respiratory infection.Hepatitis A has a variety of extra-hepatic manifestations which, if failed to be recognized, evades diagnosis.A 28-year-old lady presented with pain abdomen for
Survival of swish supreme glide track white 5.8 ±1-cm long (l.t.) juvenile perch was studied as influenced by the DBS concentration of 5 mg/l SA in tanks of equal capacities and various surface areas as well as in tanks of the same capacities and surface areas with nettings placed at various depths.Survival time was found to be dependent
Karst groundwater is highly vulnerable to contamination, which urges better land use zoning.This paper proposes a new approach, called COCKPIT-PLUS, to minimize groundwater contamination within cockpit karst regions.The method employed four parameters: P (the existence of ponor/swallow hole), L 63-1561 k&n (lineament density), U (sinking stream to
Herein, the spatial evolution characteristics of high-level Grade A tourist attractions in the Yangtze River Delta (YRD) urban agglomeration, from 2001 to 2021, are studied by comprehensively applying the nearest neighbor index, kernel density analysis, standard deviation ellipse, and spatial autocorrelation.High-level Grade A tourist attractions a
