In this article, a new multiobjective algorithm is proposed for determining the optimal sizing and allocation of photovoltaic (PV) systems in radial distribution systems. A Jaya modified to find PV capacities limited bus locations at network. The showed better performance against known techniques, results are presented. Besides, distinguished methodology improved developed based on Algorithm optimum capacity each system that satisfies an improvement voltage profile reduces power losses under...

The shadow effect caused by nearby objects or the lack of cleaning significantly affects performance photovoltaics (PV) installations. This article analyses bypass diode electrical behaviour and thermal response a PV crystalline module under shading soiling conditions. cells different substrings were covered progressively to simulate while programmable electronic DC load was connected set an operating voltage. Three tests made technology. paper characterizes in real conditions I–V curve,...

By 2050, according to the conclusion of European Commission, amount solar panels waste will reach 78 million tons. 85% all produced today belong polycrystalline panels. The subject this paper is polymer components EVA (ethyl vinyl acetate) and Tedlar® (polyvinyl fluoride). reflects studies determine chemical composition impurities panel components, degree influence on toxicity components.

Desalination membrane technology is increasingly used for water production. However, the main disadvantage of desalination related to energy consumption and CO2 emissions, so powered by renewable (RE) getting interest. In this study nanofiltration (NF) membranes have been drinking quality improvement in a pilot plant (50 m3/day) RE (11.0 kW). The aims paper are: (1) viability hybrid system improve quality, (2) availability NF desalination, (3) chemical organoleptic tap blended with...

The article reflects the experience of development and implementation a set laboratory work on recycling photovoltaic panels alternative energy. main features modernization educational process for dismantling silicon solar using virtual reality technologies, as new strategy used in environmental engineering, without risk to health students practicing some dangerous activities.

Photovoltaic panels are exposed to various external factors that can cause damage, with the formation of cracks in photovoltaic cells being one most recurrent issues affecting their production capacity. Electroluminescence (EL) tests employed detect these cracks. In this study, a methodology developed according IEC TS 60904-13 standard is presented, allowing for calculation percentage type C PV panel and subsequently estimating associated power loss. To validate methodology, it was applied...

Solar energy as a clean, renewable, and sustainable source has considerable potential to meet global needs. However, the intermittent uncertain character of solar makes power balance management very challenging task. To overcome these shortcomings, providing accurate information about future production enables better planning, scheduling, ensures effective strategies demands. The present paper aims assess performance PV output forecasting in systems using various machine learning models,...

As part this project, three open courses were created, two microelectronics one maintenance energies systems. These integrated into a cloud architecture, which are accessible to everyone. After years involved development design architecture; contents...

The Internalization process of Higher Education Institutions find, in European programme, the instruments for modernization didactic offer, according transnational high quality standards, promotion mobility staff and students, accessibility equity. DIEGO project, funded by Commission, as Capacity building field higher education, aims at establishing six innovative courses Latin American Universities with collaboration partners. project proposes implementation MOOCs use OERs, new strategy to...

In this paper, undoped and Ti-doped V2O5 thin films were fabricated deposited onto glass substrates using a «doctor blading» method. Then, the effects of Ti-doping on optical properties investigated. Titanium doping concentration 0.25-0.75 at.% has been After treatment in air at different temperatures, obtained films was characterised by various techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD) photoluminescence (PL). It found that as-obtained doped possessed...

This paper shows a solution to develop Collaborative Massive Open On-Line Courses (MOOC) among universities of three Latin American countries and European by the definition Standardization Guide as result DIEGO project. guide is necessary coordinate different actors deliver MOOC.

Abstract The article considers the method of energy efficiency improvement 0.4 kV power supply systems for enterprise located in North Krasnoyarsk territory. theoretical substantiation necessity reactive compensation is presented. reducing networks through use devices compensating proposed. this allowed costs, as well decreasing level network by 48.5% and 45% 1 st 2 nd inputs, respectively. Also, while using networks, following indicators can be achieved: increase throughput capacity...

Virtual laboratory facilities and methodological materials for work have been developed, aimed at distance learning of students in the direction "Technosphere Safety". The works reflect all features experiments research on real devices. Methodological were prepared, including video lectures work. developed virtual tested when teaching Saint-Petersburg State Electrotechnical University (ETU "LETI").

The increased integration of photovoltaics (PV) plants with energy storage systems in distribution networks needs more attention terms influence on power quality. In this paper, a new management (ESM) methodology is implemented order to increase the level PV penetration by improving voltage profile long sections electrical grid. proposed will mainly depend determining optimal system output power. optimum should be set start charging process while avoiding rise occurs. Therefore, optimization...
