Distributed renewable energy sources offer significant alternatives for Qatar and the Arab Gulf region’s future fuel supply and demand.Microgrids are essential for providing dependable power in difficult-to-reach areas while incorporating significant amounts of renewable energy sources.In energy-efficient data centers,distributed generation can be used to meet the facility’s overall power needs.This study primarily focuses on the best energy management practices for a smart microgrid in Qatar while taking demandside load management into account.This article looked into a university microgrid in Qatar that primarily aimed to get all of its energy from the grid.While diesel generators are categorized as a dispatchable distributed generation with energy storage added to handle solar radiation from the sun and high grid power operating costs in the suggested scenario,wind turbines and solar Photovoltaic(PV)are classified as non-dispatchable distributed generators.The resulting linear math issues are assessed and displayed in MATLAB optimization software using a mixed-integer linear programming(MILP)strategy.According to the simulation results,the suggested energy management strategy reduced the university microgrid’s grid power costs by 38.8%,making it an affordable solution which is somehow greater than the prior case scenario’s 23%savings.The installed solar system capacity’s effects on the economy,society,and finances were also assessed,and it became clear that the best option for the smart microgrid was determined that would be 325 kW of solar PV,25 kW of wind turbine,and 600 kW of diesel generators,respectively.Given the current situation,university administrators are urged to participate in distributed generators and adopt cutting-edge designs for energy storage technologies due to the significant environmental and financial benefits. 展开更多

Objective:To assess knowledge,attitude,and practice of medical students towards coronavirus disease 2019(COVID-19).Methods:A self-designed questionnaire was developed and given to the students of a government medical college in Uttarakhand.The demographics,mean knowledge,attitude,and practice of the participants were investigated,and the scores were calculated.t-test and ANOVA were used for statistical analysis.Results:Out of the total participants(n=354),50.3%were male and 54.5%were 21-23 years.Almost all the participants(96.6%)increase the frequency of washing hands under the influence of COVID-19.Although no significant relationship was found between different religions,age-categories in terms of knowledge,the participants who were aged 21-23 years had higher knowledge.In addition,gender had a significant impact on practice scores(P<0.05)while no demographic variable was found to have a significant relation with attitude score(P>0.05).Conclusions:The majority of the participants had good knowledge,positive attitude,and sufficient practice.Females and males have significantly different practices.Although the results are very positive,it is suggested that people should continue to strengthen knowledge,attitude,and practice towards COVID-19,so that India can win the battle against the disease. 展开更多
