Comprehensive Study of 3-Level Stabilizer in Hybrid PV and Wind Energy Systems- A Review

When variables are bounded so that almost the whole constraints are satisfied, power system stability is typically characterized as an electric power system's ability to restore a situation of functioning equilibrium after being subjected to a physical disturbance.This paper presents a thorough investigation of three-level stabilizers in a hybrid PV Wind Energy system that is integrated with the power system. From a hybrid renewable energy system that is linked to the grid and studied with a stabilizer that uses a variety of control algorithms based on artificial intelligence algorithms developed by several researchers

Comparative analysis of predictive models for SOC estimation in EV under different running conditions

Electric vehicles have been introduced to address environmental concerns related to excessive burning of fuels in the automobile industry. The key component solely responsible for its preferences over other modes is the battery. The Charging and discharging states under different running model of vehicle is directly related to the health of battery and thereby the degree of hybridization of the series-parallel hybrid electric vehicle (SP-HEV) considered in this research. In this study, the state of charge of a series parallel hybrid electric vehicle was continuously modeled under different driving conditions, and two models were used to predict the charging states of the battery. A swarm-based prediction model resulted in a prediction error of 0.9114, while a modified differential evolutionary method reduced the error to 0.6672, indicating its effectiveness in estimating battery charge conditions. The prediction of battery SOC will enhance the power efficiency of the vehicle along with its SOH

Potentiating Metronidazole Scaffold against Resistant Trichomonas: Design, Synthesis, Biology and 3D–QSAR Analysis

Metronidazole (MTZ), the FDA-approved drug against <i>Trichomonas vaginalis</i> (TV), is being challenged seriously by drug resistance, while its inertness to sperm makes it ineffective as a vaginal contraceptive. Thirteen piperidine dithiocarbamate hybrids of 2-(2-methyl-5-nitro-1<i>H</i>-imidazol-1-yl)­ethane (<b>8</b>–<b>20</b>) were designed to potentiate the MTZ framework against drug resistance and sperm. New compounds were 1.2–12.1 times more effective against MTZ-susceptible and -resistant strains of TV. All of the compounds exhibited high safety toward cervical (HeLa) cells and <i>Lactobacillus</i>. Thirty-eight compounds were scrutinized by CoMFA and CoMSIA techniques of 3D quantitative structure–activity relationship. Good predictive <i>r</i>_pred² values for CoMFA and CoMSIA models reflected the robustness of the predictive ability. This was validated by designing five new analogues (<b>46</b>–<b>50</b>), which were potently microbicidal (3–10 and 10–20 times against MTZ-susceptible and -resistant TV, respectively) and spermicidal. This in vitro study may have significant clinical relevance, which could become evident in due course
