A comparative study of model fitting for estimating the overall efficiency of grid-connected photovoltaic inverters
Authors: J. Ramos-Teodoro  , F. Rodríguez  , M. Pérez  , M. Berenguel
Published: September 2021

Determining the static overall efficiency of inverters is sometimes necessary for control o design purposes. As getting this information from the manufacturers’ datasheets or certified laboratories might not be always viable, this paper addresses its estimation from direct measurements under actual operating conditions. Particularly, the Sandia Inverter Model has been taken as a paradigm of methodology and adapted to deal with the available data for an office building’s photovoltaic system over the 2013- 2017 period. Two unidimensional and two bidimensional models have been selected and compared to assess their goodness of fit on three inverters of the same kind of which the system consists. The best-case scenario corresponds to an exponential curve fitting, in which the R-square value increases over 0.95, outperforming the other models.
A Brief Introduction in the Mitigation of Conducted Electromagnetic Interference Issues
Authors: M. Buzdugan
Published: September 2021

This paper deals with the mitigation of the influence of electromagnetic conducted emissions in low voltage grids, which can be performed using different filtering methods. Due to the relatively young age of the electromagnetic compatibility domain, the specific terminology is not yet fully consecrated. That is why the specific literature abounds in a bunch of definitions and notions, incomplete, redundant, or worse, even contradictory. Therefore, all over this paper, the terminology from the successive issues of the standard IEC 60050-161 International Electrotechnical Vocabulary, is used. The introductory section presents generalities regarding the broader context of electromagnetic compatibility in which the paper fit. Section II is devoted to measurement techniques and measuring equipment used in conducted electromagnetic interference tests, specifically for electromagnetic emissions that flow in/from the equipment under test through power lines in the standardized frequency range from 100 kHz to 30 MHz. These measurement techniques and equipment are further used in the next section which presents electromagnetic interference experiments, performed on an induction motor driven by a frequency converter. To mitigate the conducted electromagnetic emissions to fit into the standard limits, a cascade of two EMI filtering cells has been designed and implemented. This demonstrated the usefulness and effectiveness of mains EMI filters in low voltage power applications. The experiment also demonstrated that in some cases it would be necessary to retrofit more than one filtering cell.

Loss Analysis Due to Influence of Harmonics in a Distribution System
Authors: R. M. Soares  , M. E. Oliveira  , M. A. A. Freitas  , G. P. Viajante
Published: September 2021

The electrical system is subject to rules to guarantee a standard, where several factors can reduce its quality. This can lead to undesirable consequences, such as increased electrical losses in the distribution. As the technology advances and the constant presence of non-linear loads, the electrical network is subject to harmonic distortions that increase the effective value of the current, resulting in inconvenient effects, such as increased losses. In another words, a bigger fraction of the energy is lost by Joule effect and a smaller fraction came to the final consumers. In Brazil, the regulatory agency, in its recommendations, does not consider the effect of harmonic components, obtaining lower results for losses. So, to analyze the influence of these distortions on the operation of a distribution network, simulations were done with the test system LVTestCaseNorthAmerican, with 390 buses. Three distinct climatic cases were analysed, each with a load shape generated from fuzzy logic, all considering the presence of non-linear loads. The simulations were made in OpenDSS, and the losses demonstrated for the three situations. Finally, the importance of considering these distortions in the calculation of losses is discussed.

Authors: Rafael Martins Leite  , Jonas Villela de Souza  , Eduardo Nobuhiro Asada  , Mário Oleskovicz
Published: September 2021

This paper aims to examine the increasing integration of distributed energy resources in the low voltage distribution grid. Considering the current increasing of distributed photovoltaic generation in Brazil, there is a deterioration of specific indices related to power quality, such as overvoltage and voltage unbalance. In this sense, a survey of these problems, the severity assessment via simulation of a real system and the proposal of improvement in the associated indexes using energy storage devices are made. The resulting analyses contemplate both the current reality of growth in the distributed photovoltaic generation and the joint integration of these generators with energy storage systems, thus enabling a comparison of results focusing on the electricity grid impacts. The study has improved the network's operation, reducing the power quality aggravating factors and increasing the local consumption of the energy generated locally. The total losses on the original network were reduced by up to 52.6%, the voltage drop to 74.7% and the voltage rise was completely eliminated.
Fuses in distribution systems: new applications in DC circuits
Authors: J. C. Gómez  , D. Tourn, C  , C. Reineri  , F. Romero
Published: September 2021

The vast majority of distribution systems currently in use, work with alternating current at 50 Hz or 60 Hz. Several of the distributed resources (generators or storage) supply electrical energy in the form of direct current. Also, there are continuous end-use applications such as centralized variable speed drives, and the rapidly growing application in electric cars which has recently started. This panorama leads to the growing interest in the application of fuses in direct current systems, not as an adaptation of the alternating current fuse but as a specific design. The article presents the crucial differences between direct and alternating circuits, oriented to the operation of the fuse, highlighting their advantages and disadvantages, citing the complications in the design that are required for this growing application. The continuous operation of the fuse is explained in its three fundamental parts: pre-arc, arc and post-arc. The most important current applications are analyzed, such as the protection of: circuits with batteries, circuits of electric vehicles for individual use, power electronics, photovoltaic cells, public transport and circuits in mining. It is concluded in the need to deepen the study of these applications in order to achieve specific fuses designs for direct current and not mere adaptations of the traditional alternating current fuse designs.

Published: September 2021

As a renewable energy source and an alternative tofossil fuels, the wind power industry is growing rapidly. However,due to harsh weather conditions, wind turbines (WT) still face manyfailures that raise the price of energy produced and reduce thereliability of wind energy. Hence, the use of reliable monitoringand diagnostic systems of WTs is of great importance. Operationand maintenance expenses represent 30% of the total cost of largewind farms. The installation of offshore and remote wind farmshas increased the need for efficient fault detection and conditionmonitoring systems. In this work, without using specific customdevices for monitoring conditions, but only increasing the samplingfrequency in the sensors already available (in all commercial WT) ofthe supervisory control and data acquisition system (SCADA), data-driven multiple fault detection is performed, and a classificationstrategy is developed. The data is processed, and subsequently,using a convolutional neural network (CNN), six faults are classifiedand evaluated with different metrics. Finally, it should be noted thatthe classification speed allows the implementation of this strategyto monitor conditions online in real under-production WTs.

Published: September 2021

This study presents a techno-economic assessment of the use of Linear Fresnel Solar Collectors for the heat supply in traditional fruits and vegetable processing industries in Almeria’s province. This assessment is justified by the high availability of solar radiation in the area under study, the evaluation of complementary energy self-consumption modalities, and the suitability of using local resources for the preservation and improvement of traditional productive activities. The work starts with an identification of the potential user’s needs and their location in the province. Afterward, the solar radiation resources have been estimated as they constitute one of the basic inputs for sizing the proposed systems. Together with the above, representative thermal demands have been considered and different configurations of commercial Linear Fresnel Solar Collector thermal plants aimed to contribute to solarize the analyzed productive processes have been designed and the corresponding techno-economic assessment have been undertaken. Main findings advance the profitability that can be achieved with this technology, reaching, after an optimized integration of the solar plant in the industrial process, a solar fraction between 66-82 % and payback periods of the investment between 6-12 years.

Electric vehicles, along with renewable energy, are two of the most important components for achieving a more sustainable and cleaner future. This paper study the Spanish electricity demand at the Iberian Peninsula level during the eleven-year period 2007-2018 with daily data from the Spanish electricity network, calculating the monthly daily average for each year as actual data on the use of the electricity distribution network. Having in mind this information, the number of electric vehicles (EVs) that could be charged in Spain is being studied in order to reorganize the Spanish production system. Three different scenarios are analyzed (slow, accelerated and fast charging) according to the capacity conditions of the electric distribution network, previously determining the available electric energy that varies according to the electric demand. Results obtained reveals the need of a complex reorganization of the Spanish electricity production system due to the geographical seasonality of electricity demand.

Published: September 2021

Green Artificial Reefs (GARs) are marine structures to exploit sea resources in a sustainable way (produce food resources, improve the tourism, etc.). They should be installed on the seabed, process that is not usually easy. Therefore, their installation process should be clearly defined. The aim of this paper is to propose several methods for installing a group of green artificial reefs designed in the PROARR research project. Two of these methodologies are conventional: a bulkcarrier and a special service workboat. The other technique is innovative: an autonomous vehicle. All of them offer different results in terms of maneuverability, positioning, precision and cost. This study will compare these four methods of installing green artificial reefs to improve the knowledge about this type of sustainable way of exploiting the marine resources.

Authors: KÜÇÜKOSMANOĞLU Alp , ARLI KUCUKOSMANOGLU Özen
Published: September 2021

The Bosphorus is a heritage from the past to the present with its natural, historical and cultural features. Vessels passing through the Bosphorus, which is a narrow waterway, create a risk in Istanbul Strait. Thousands of vessels carrying dangerous cargoes pass through the Bosphorus every year. In this study, the changes in the cargos carried by these vessels and number of vessels over years are examined. It is seen that approximately 44000 vessels per year have passed through considering the last decade. The data of Ministry of Transport and Infrastructure, General Directorate of Marine between the years 1995 and 2020 has been used to estimate the change of the number of the vessels for five years period. Although the estimation show that the vessels numbers will decrease with an estimation of ~32,250 vessels for the year 2025, the total gross tonnage will increase in the future years. The results show that, while the number of bulk carrier vessels, livestock carriers, passenger ships and refrigerated cargo carriers will increase, the number of general cargo vessels will decrease in the future years.

The Fourth Industrial Revolution (IR 4.0), which is complementary to the technological revolution, has given birth to Financial Technology (Fintech). Numerous advantages are offered by Fintech, yet the adoption rate is still low. This is especially from the employed fresh graduates’ perspectives that are regarded as the computer literate and IT savvy’s group. This research aims to examine the factors that affect the technology acceptance of Fintech payment services. The research attempts to measure the relationships between performance expectancy, effort expectancy, social influence, facilitating condition and consumers’ trust with the adoption of Fintech. Based upon the Unified Theory of Acceptance and Use of Technology (UTAUT), the quantitative method was employed via online survey of 179 respondents. The result showed that consumers’ trust had the highest impact on the adoption of Fintech payment services, followed by performance expectancy and effort expectancy. In contrast, facilitating conditions and social influence showed an insignificant relationship with the adoption of Fintech payment services. This finding would enhance the awareness for people to become more open towards the acceptance of Fintech for their daily transactions. Fintech companies are expected to develop into more secure services and design better products in becoming a cashless society.

Authors:   Mercu Buana University, Indonesia, Faliana Robick , Utami Wiwik ,   Mercu Buana University, Indonesia
Published: September 2021

The governance mechanism is different for each company. Therefore, companies need an indicator to measure the quality of governance and one of them is the ASEAN Scorecard. This indicator is used as a standard for measuring the quality of corporate governance in the ASEAN region. The corporate governance mechanism can be a factor in price changes in the stock market. Investors will react to any issues related to it. Price changes that occur on the stock market are a measure of the size of investors in investing because they can affect expected earnings. Although there is quite a lot of research related to it, research on earnings quality that discusses market response to price changes that occur due to the influence of governance mechanisms is limited. This study aimed to examine the effect of corporate governance on earnings quality using companies listed on the Financial Time Stock Exchange ASEAN Star (FTSE ASEAN Star). The study was conducted by examining financial ratios of companies using a cross-sectional data regression model with the Earnings Response Coefficient (ERC) as a proxy. The results showed that corporate governance affected ERC, especially on the disclosure of corporate governance and shareholder rights. Keywords: ASEAN scorecard, corporate governance, earnings response coefficient, disclosure, fraud

This study examined the effectiveness of regulatory capital in enhancing efficiency and credit growth and reducing bad loans in commercial banks listed on the Pakistan Stock Exchange (PSX) from 2010 to 2019. Precisely, the impact of capital adequacy ratio (CAR) was studied on net interest margin (NIM), credit growth (CR) and non-performing loans (NPLs). The impact of capital adequacy regulations was assessed by retrieving data from financial statements analysis (FSA), Bank Financial statements and the World Bank website. Panel regression models including ordinary least squares (OLS), fixed and random effects under robust title were applied in this study. Results revealed that the implementation of stringent CAR plays the role of panacea and increases interest margin & credit growth and a reduction of NPL in Pakistani commercial banks. The study provides practical results for regulators to customize regulations on credit growth to reduce non-performing loans and maintain healthy growth of loans by not compromising on interest margins as well as maintenance of minimum capital adequacy ratios. With the high significance of stringent minimum capital adequacy for banks, the findings of the study are valuable for regulators, banks, auditors and investors, as capital adequacy ratio commonly plays the role of Panacea in terms of efficiency, credit growth and reduction in non-performing loans. Keywords: capital adequacy ratio, efficiency, credit growth, non-performing loans

Published: September 2021

About 2.5 million hectares of a total of 15 million hectares of oil palm plantation in Indonesia are planted in, or conflict with, the forest zone. Oil palm plantations face a conflict between socio-economic and ecological issues. This study was conducted in the Harapan Rainforest, Jambi to evaluate the potential of oil palm-based agroforestry to reconcile economic and ecological interests, by considering socio-economic and financial feasibility as well as biodiversity and land cover. The financial feasibility of oil palm agroforestry is compared to oil palm monoculture, employing a discounted cash flow approach using three indicators: net present value (NPV), benefit-cost ratio (BCR), and internal rate of return (IRR). Two ecological indicators—biodiversity and land cover—are evaluated in an experimental plot of oil palm agroforestry in Jambi. This study indicates that the NPV, BCR, and IRR of oil palm monoculture are IDR 62,644,836 (US$ 4,476.84), 1.39, and 20.77%, respectively, while the oil palm agroforestry planted in the experimental plot potentially generates much better values of financial indicators with NPV, BCR, and IRR being IDR 209,221,212 (US$ 14,951.76), 1.79, and 24.42%, respectively.  Besides evaluating financial feasibility, we also found that the reviewed current studies indicate that the oil palm agroforestry provides positive ecological impacts, such as increased forest land cover, invertebrate fauna, and bird diversity.

Kajian kehampaan gabah pada berbagai varietas padi dikaitkan dengan deraan angin dan curah hujan tinggi masih jarang dilakukan di Indonesia. Penelitian bertujuan mengevaluasi tingkat kehampaan beberapa genotipe padi pada perlakuan angin dan hujan selama masa generatif. Penelitian dilaksanakan di Kebun Percobaan IPB Leuwikopo, Bogor, Indonesia pada Oktober 2017-Januari 2018 menggunakan pot ember ukuran 13.9 L. Genotipe Ciapus, Fatmawati, HIPA 6, Inpari 10, dan Way Apo Buru (WAB) pada fase generatif didera angin kecepatan 10-40 km jam-1 pukul 07.00-17.00 WIB, hujan pukul 07.00-12.00 WIB, dan hujan pukul 07.00-17.00 WIB selama dua minggu. Perlakuan angin dan hujan meningkatkan jumlah gabah hampa, dengan tingkat kehampaan malai tergantung genotipe. Tanaman memperoleh perlakuan hujan pukul 07.00-17.00 memiliki persen gabah hampa lebih besar dari hujan pukul 07.00-12.00 khususnya pada genotipe WAB. Kehampaan malai pada genotipe WAB sensitif terhadap curah hujan, dan Ciapus, HIPA 6 dan Inpari 10 sensitif terhadap angin. Fatmawati relatif lebih tahan deraan angin dan hujan dibandingkan genotipe lain. Penelitian menunjukkan perlunya memilih genotipe untuk mengurangi dampak deraan angin dan curah hujan selama masa generatif.

Seleksi secara fenotipik, terutama terhadap cekaman abiotik, seringkali sulit dilakukan. Kegiatan seleksi secara molekuler diperlukan untuk mengidentifikasi hingga taraf molekuler bahwa suatu sifat toleran terbukti secara genotipik. Tujuan dari penelitian ini ialah untuk mengkonfirmasi sifat toleransi kekeringan galur-galur padi secara molekuler menggunakan marka SSR RM164, RM228, RM248, dan RM328. Penelitian dilaksanakan di Laboratorium Bioteknologi LIPI, Cibinong pada bulan November hingga Desember 2017, menggunakan teknik polymerase chain reaction (PCR). Hasil penelitian menunjukkan bahwa marka RM228 terkait dengan karakter skor menggulung, panjang malai, tinggi tanaman dan umur berbunga, sedangkan RM328 terkait dengan panjang malai, jumlah anakan, jumlah gabah isi per malai, dan produktivitas. Marka tersebut diduga dapat digunakan untuk seleksi toleransi kekeringan. Tujuh dari sepuluh galur yang terindikasi toleran terhadap cekaman kekeringan fase generatif berdasarkan skrining secara artifisial terkonfirmasi secara molekuler berada dalam satu kelompok dengan varietas pembanding toleran ‘Limboto’. Ketujuh galur tersebut ialah B13983E-KA-12-2, B13507E-MR-19, B14366E-KY-50, BP20452e-PWK-0-SKI-1-1, BP20452e-PWK-0-SKI-2-4, BP20452e-PWK-0-SKI-3-3, dan BP29790d-PWK-3-SKI-1-5.

Objetivo: conocer la percepción del concepto de “saludable” y su relación con las marcas de alimentos en un grupo de adolescentes de la ciudad de Medellín, Colombia. Metodología: se desarrolló una investigación bajo el enfoque empírico analítico, con un diseño cuasiexperimental y un alcance transversal. Se contó con la participación de 159 adolescentes (88 hombres, 70 mujeres, 1 otro), con una edad media de 16 años, estudiantes de dos instituciones educativas de carácter privado. Resultados: se encontró que los adolescentes perciben como saludable los alimentos independientes de la marca, pero la marca que se concibe como saludable determina su elección frente a un alimento que incluso no pueda contar con beneficios nutricionales. Limitaciones: se identificó como limitaciones del estudio, el estrato socioeconómico de la muestra, dado que todos los participantes pertenecían a un nivel socioeconómico alto (5 y 6), lo que permite inferir que su experiencia con ciertos tipos de alimentos puede estar influenciada por el acceso a los mismos, lo que determina los hábitos y el comportamiento de consumo. Conclusiones: el concepto de lo “saludable”, el cual fue el objeto de estudio de esta investigación, se encuentra fuertemente permeado por las actividades de mercadeo de la industria de alimentos y poco respaldado por la calidad nutricional real de los alimentos, así mismo este concepto se construye en la medida que los consumidores dependiendo del nivel socioeconómico tiene la posibilidad de acceder o tener experiencias con ciertos productos.

Teknologi gasifikasi tipe downdraft adalah salah satu teknologi untuk mengkonversikan bahan bakar padat atau biomassa padat secara thermokimia dengan temperatur 6000-7000 C menjadi bahan bakar gas mampu bakar dengan kebutuhan udara 20 – 40% Stoikiometri dimana suplai udara masuk dari atas menuju dasar reaktor dan proses gasifikasi terjadi di dasar reaktor.  Sampah kota atau ( Municipal Solid Westes) adalah bahan buangan yang terdiri dari bahan organik dan anorganik yang mempunyai nilai kalor sehingga dapat digunakan sebagai bahan bakar. Penelitian ini bertujuan untuk mengetahui performansi dari gasifier tipe dwondraft dengan variasi perlakuan awal bahan bakar kering, pellet, dan briket. Perbedaan perlakuan bahan bakar akan menghasilkan nilai kalor dan karakteristik bahan bakar yang berbeda sehingga nantinya akan didapatkan bahan bakar yang paling efektif. Hasil penelitian menunjukan bahwa efisiensi tertinggi didapatkan pada variasi perlakuan awal bahan bakar sampah kota yang di briketkan yaitu sebesar 61,32% dan FCR tertinggi terjadi pada bahan bakar pellet yaitu 4,61 kg/jam.

Gasification type Downdraft technology is one technology to convert thermochemical solid or biomass fuels with temperatures of 6000-7000 C into combustible gas fuels with air requirements of 20 - 40% Stoichiometry where the supply of air enters from above to the reactor base and gasification process occurs at the bottom of the reactor. Municipal solid waste is a waste material consisting of organic and inorganic materials that has a heating value, so that it can be used as fuel of gasification. This study aims to determine the performance of the dwondraft gasifier with variations in the pretreatment of dry MSW, pellets and briquettes. Differences in fuel treatment will produce different heating values ??and fuel characteristics so that the most effective fuel will be found later. The results showed that the highest efficiency was found in the variation of initial treatment municipal solid waste briquettes which was 61,32%, and the highest FCR occurs in pellet fuel which is 4.61 kg / hour.
