Abstract With the gradual advancement of dual-carbon goals, wind-solar-storage power station has become mainstream trend in constructing new energy stations due to their wind and luminous complementary characteristics. However, current research on primary frequency control is still focused a single-machine strategy. The communication delay period caused by long links are not considered. It diff...

As more inverter-connected renewable resources are integrated into the grid, frequency stability may degrade because of reduction in mechanical inertia and damping. A common approach to mitigate this degradation performance is use power electronic interfaces for primary control. Since can realize almost arbitrary responses changes, they not limited reproducing linear droop behaviors. To fully l...

objective: to compare the frequency of helicobacter pylori (h. pylori) infection in subjects with primary open angle glaucoma (poag) vs controls. methods: in a case-control study, 44 patients with primary open angle glaucoma and 79 patients with senile cataract (control group) were investigated for serum level of anti-h. pylori antibody using the enzyme-linked immunosorbant assay (elisa) method...

this paper presents a cooperative control which is applied to the secondary control of a microgrid controlled via a multi-agent scheme. balancing power that leads to voltage and frequency stability in a microgrid is essential. the voltage and frequency regulations are limiting within the specified limits and conveying them to their nominal values. limiting and conveying the voltage and frequenc...

In this paper, an attempt has been made to introduce a new control strategy including Plug-in Hybrid Electric Vehicle (PHEV) and Diesel engine generator to control the voltage and frequency of autonomous microgrids. The proposed control strategy has multiple advantages over the recent control methods in microgrids. The proposed method applies the primary and secondary frequency control strategy...

objective(s) primary or adult type hypolactasia, the most common enzyme deficiency in the world, is due to reduced lactase activity in the intestinal cell after weaning. lactase non-persistence is inherited as an autosomal recessive trait. a dna variant, single nucleotide polymorphism c/t−13910 which is located on 13910 base pairs (bp) upstream of the lactase gene (lct) at chromosome 2 has been...
