Multi-conductor Line Models for Harmonic Load-flow Calculations in LV Networks with High Penetration of PV Generation

引用

journal of Modern Power Systems and Clean energy 2022年第5期10卷 1288-1301页

作者： Fernando M.Camilo M.e.Almeida Rui Castro V.Fernao pires Institutode engenhariade Sistemas e Computadores Investigacao eDesenvolvimento(INESC-ID)and TecnicoUniversity of LisbonLisbonPortugal eSTSetubal Polytechnics of SetubalSetuibalPortugal

Low-voltage(LV) distribution networks are unbalanced and present loads with nonlinear behavior, which introduce harmonics in the networks. The predictable increase in photovoltaic microgeneration(PV μG) accentuates this unbalanced characteristic, as well as poses new technical problems,namely voltage rise and reverse power flow. To accurately account for the distributed PV and loads in the LV network, unbalanced three-phase power flow algorithms should be utilized,where different approaches may be used to represent lines with various degrees of accuracy. The more accurate algorithm considers the electromagnetic coupling between the line conductors,whereas the simpler algorithm represents each conductor of the line as a single-phase line with pure resistive behavior. This paper aims to analyze the influence of the line model on the load flow in a highly unbalanced LV network with a high penetration of PV production, and considers the impact of the harmonics produced by nonlinear loads. Based on the results obtained,it is possible to identify the most suitable model to be used, depending on the study to be performed. Different scenarios of PV generation and loads are addressed in this paper.

Development of metal organic fromwork-199 immobilized zeolite foam for adsorption of common indoor VOCs

引用

journal of environmental Sciences 2017年第5期29卷 321-330页

Reticulated foam shaped adsorbents are more efficient for the removal of volatile organic compounds（VOCs）,particularly from low VOC-concentration indoor air streams. In this study composite structure of zeolite and metal organic frameworks（MOFs）,referred as ZMF,has been fabricated by immobilization of fine MOF-199 powder on foam shaped Zeolite Socony Mobil-5（ZSM-5）Zeolitic structure,referred as ZF. The ZMF possess a uniform and well-dispersed coating of MOF-199 on the porous framework of ZF. It shows higher surface area,pore volume,and VOCs adsorption capacity,as compared to ***-fabrication changes in selective adsorption properties of ZMF were studied with three common indoor VOCs（benzene,n-hexane,and cyclohexane）,using gravimetric adsorption technique. The adsorption capacity of ZMF with different VOCs follow the order of benzene 〉 n-hexane 〉 cyclohexane. In comparison with MOF-199 and ZF,the composite structure ZMF shows improvement in selectivity for benzene from other two VOCs. Further,improvement in efficiency and stability of prepared ZMF was found to be associated with its high MOF loading capacity and unique morphological and structural properties. The developed composite structure with improved VOCs removal and recyclability could be a promising material for small to limited scale air pollution treatment units.

Soil salinization and non-point source pollution are among the most important and widespread environmental problems in european Mediterranean regions. Sweet sorghum （Sorghum bicolor （L.） Moench var. saccharatum） is a moderate to high salinity tolerant crop with low water and nutrient needs, seen as an alternative to grow in the water scarce regions. A three-year multifactorial study was conducted in southern Portugal to evaluate the combined effects of saline water and nitrogen application on the dry biomass （total, stems, and leaves）, sugar content （total reducing sugars and sucrose eontents） and sugar yield （here defined as the product of total reducing sugars and stems dry biomass） functions of sweet sorghum. Sorghum dry biomass and sugar yield showed diminishing returns for each incremental change of nitrogen. The use of saline irrigation waters also led to yield reduction. exception was sucrose content which increased with increasing levels of sodium in the soil. Nitrogen need decreased as the amount of sodium applied increased. Stem dry biomass, sucrose content, and sugar yield progressively increased with progress in the experiment. The effect could be attributed to the increase of the amount of irrigation applied throughout the years, thus increasing the leaching fraction which promoted salt leaching from the root zone, reduced the salinity stress, increased plant transpiration, nitrogen uptake and biomass yield.
