Published: July 2024

The ability of power systems to withstand and recover from natural events, like storms, earthquakes and floods is referred to as resilience. These events may not happen often. They can cause damage to infrastructure and disrupt the supply of electricity. That's why it's crucial to consider resilience when planning and operating networks. In this paper we present a method to enhance the resilience of distribution networks these are the parts of the system for delivering power to end users. Our approach involves dividing the distribution network into subnetworks called microgrids. Each microgrid operates independently. Includes sources of generation loads (consumers) and storage devices. These microgrids can function as part of the grid. Operate autonomously in what we call island mode during major disturbances. In situations they can isolate themselves from the grid and use their internal resources to continue providing electricity specifically for critical needs. To assess how well our approach performs we introduce a measure called a resilience indicator. This indicator evaluates how effectively users electricity demands are met during and after a disturbance occurs. It can be calculated individually for each microgrid or holistically, for the distribution network by considering how these microgrids interact with each other. Our research demonstrates that the method we propose can improve the reliability of the power distribution network. We achieved this by comparing the results obtained from our approach with those, from a network that does not use microgrids. Our paper adds to the existing knowledge, on the resilience of power systems by introducing a technique centered around creating multiple independent microgrids. Key words.

Image processing to calculate flame velocity based on Deep Learning
Authors: De-La-Cruz Celso ,   Department of Engineering, Pontifical Catholic University of Peru, Torres Josué , Rojas Freddy
Published: July 2024

Flame velocity is one of the main characteristics of combustion. One of the methods to measure flame velocity is to determine the flame area by approximating the shape of the flame to a flat, conical, or truncated cone surface. To increase the precision in the calculation of the flame area and thus improve the calculation of the flame velocity, the use of semantic segmentation of the image is proposed to determine the flame image contour and then obtain the flame area with an integral calculation. Semantic segmentation was performed using the U-net structure. The results were compared with other classical image processing techniques showing the advantages and disadvantages. The results show that semantic segmentation based on Deep Learning segments the flame image with high precision even under changing conditions such as flame color variations and background imperfections. Key words. Laminar flames, burning velocity, image processing, deep learning.

Integrated wind farms face significant challenges due to strict grid code requirements. Maintaining voltage stability is especially important for wind farms that are connected to the electrical grid. This research paper examines how FACTS devices, specifically Static Synchronous Compensators (STATCOMs), can be used to resolve voltage stability issues in wind farms and fuel cell power plants that employ Double Fed Induction Generators (DFIGs) and are connected to both loads and the power grid. During fault ride-throughs and power outages, wind farms face challenges such as voltage dips and fluctuations, which can negatively impact the grid. As a result, wind turbines require a stable grid to function effectively. In the absence of voltage stability measures, wind farms may experience reduced productivity, equipment failure, and downtime. As a dynamic voltage restorer, FACTS devices will be used. Thus, stable voltage levels are maintained, and power interruptions are prevented at DFIGbased wind farms. Three-phase impedance faults on load buses and 25% voltage sags on high voltage buses were examined in this study. STATCOMs were implemented as dynamic voltage restorers during fault ride-throughs and power grid disruptions in the MATLAB/SIMULINK simulations to mitigate voltage dips and fluctuations experienced by wind farms and fuel cells. Simulation results showed that STATCOMs significantly reduced downtime, increased power output, and minimized equipment failures in wind farms. Index terms: DFIG, Wind turbine, short circuit, Voltage Sag and STATCOM.

Climate change is a global phenomenon which is becoming increasingly concerning. International efforts, such as the Paris Agreement [1] lead to transport electrification initiatives. HYPOBATT [2], in marine sector, aims for the charger that will enable a full electric vessel to be a reality. These systems have great amounts of energy storage. Together with electric machinery, EMI filters and distribution grids usually can sum up to some mF capacitance to earth, becoming a problem when detecting faults to ground, and therefore, a safety issue. To detect earthing faults insulation monitoring devices (IMD) are used, but as of Jan. 2024, the commercial IMDs available are not able to make a good measurement at stray capacitances (CS) above 3000µF [3], and all the devices in the mF range have response times of >100s. A new Distributed Insulation Monitoring Strategy (DIMS) approach is proposed in this paper, with simulation results, to make a faster and more reliable measurement of earthing faults in isolated terra (IT) systems with stray capacitances in the range of the hundreds of µF. The impedance to ground is measured in isolated parts of the whole system and then a higher-level logic is implemented to compute a total safety status. Key words.

The decarbonization of the power sector is undertaking a global transformation with different roadmaps, inclusion of new generation technology and different legal frameworks. In the last years, the costs of renewables have dropped substantially allowing them economically competitive with conventional fuels, in most global markets. However, the isolated electrical systems are facing a huge challenge to face the energy transition and at the same time, to reach the energy sovereignty, to avoid the external dependence of the energy importation. In this sense, the generation capacity by renewable energies requires the inclusion of enough accumulation capacity to accomplish the generation with the demand curve. Also, the mobility transition will play a remarkable role due to the transition to electrical, hybrid and e-fuels powered vehicles. Key words.

The paper describes a method how to measure the high-power, high-voltage transformer that is used in LLC converter based on GaN transistors. These transistors allow high frequency switching which reduces the power losses and minimizes the form factor. On the other hand, this high frequency is challenging due to the parasitic parameters of the transformer. To achieve soft switching with Zero Voltage Switching (ZVS) on the primary side and Zero Current Switching (ZCS) on the secondary side it must have predictable properties and it must be considered in the controller design. This paper presents measurement of real parameters of given transformer and how to consider its properties in the converter’s design using the SPICE simulations. Key words.

. All over the world, regulatory frameworks promote energy efficiency in the building sector. In 2015, the Colombian government issued Energy Regulations 0549. This regulation establishes the minimum percentages of energy savings that new buildings must meet. Almost ten years after the issuance of this standard, there is no evidence of a technical study that uses a case study to evaluate the degree of compliance with the regulations of a typical residential building. This study analyzes the construction characteristics and obtains the energy model of a middle-income multifamily building built after the issuance of the standard to evaluate the degree of compliance with the standard and the effectiveness of its mechanisms. The results show a partial integration of the recommended energy-saving measures and the absence of precise instruments to guide the builder in the evaluation tasks. . Key words.

Potential broad impact: Integrating solar, wind, and conventional energy to feed the electrolyze after completion of the electrochemical process will produce two streams of O2 and H2. The hydrogen stream will be stored and provided with uninterrupted feed to a catalytic reactor in the presence of CO2. It will produce EMethanol[1]. However, this depends on these resources' reliability, cost, and availability, with the highest potential for expansion to the size needed for large-scale deployment to produce e-methanol[2]. This is known as electro-fuel, which provides electricity and fuel for electric and diesel vehicles[3][4]. As witnessed the versatility of Hydrogen in these applications highlights its significance in various industrial sectors. As the world looks towards sustainable and clean energy solutions, the role of Hydrogen is expected to grow even further [5]. However, the central part of Hydrogen is produced from fossil fuels (known as gray and brown Hydrogen) [6], and only a minimal amount of almost 4% is delivered through an electrolysis process using renewable energy to complete the chemical process [7], known as green Hydrogen. The transition to a more sustainable hydrogen economy involves scaling up the production of green Hydrogen through electrolysis and advancing technologies to improve efficiency and reduce costs associated with this process [8],[9]. Recently research indicated that production and consumption of the Green Hydrogen is the future of sustainable power delivery by replacing fossil fuel [10]. The fossil and Biomass also catalyzing the GHG (Green House Gases) with high carbon intensity, this is biggest challenge to deliver clean energy [11]. In the first instance, this research proposed an integrated Modular, which incorporate Renewable(photovoltaic) and Conventional Power sources to complete electrolysis process and its port equipment(s) to deliver uninterrupted clean Energy inform of Liquid Green Hydrogen for Electricity and to replace diesel [12]]13].

Managing plug-in electric vehicles (PEVs) recharging with different capacities can achieve the optimum operation schedule. Otherwise, stability issues for the microgrid may occur. Therefore, Energy management becomes essential for charging stations to meet the complexity of bidirectional power flow and multiple resource availability. This paper presents an energy management system of PEVs based on multiple resources managed by a DC microgrid. Three main resources are used: the national grid, Photovoltaic cells (PV), and Battery. The grid and PV cells are centralized distributed, whereas Batteries are decentralized distributed. Balance options are defined to match the vehicle requirements based on power availability, even the surplus power between the connected vehicles. The aims are to optimize grid energy usage, long life of the storage devices, and improve resilient power to the load demand. Metaheuristic methods (PSO) are used to enhance the response to the charging station operator. The results show that electric vehicles are a promising solution to keep the voltage stability of the grid in a high-demand approach. The PV is a flexible and cheap resource to recharge electric vehicles and synergize the national grid. Sometimes, trading power from a high state of the charging PEV to a lower one is beneficial to maintain the stability of the charging station. Keywords: microgrid, charging station, Electric vehicles, multiple resources, voltage stability.

According to the Portuguese Roadmap for Carbon Neutrality 2050 (RNC2050), Portugal aims to achieve carbon neutrality by 2050. To achieve this goal, it is necessary to decrease the consumption of primary energy from non-renewable sources and increase the consumption of energy from renewable sources. Portugal has a high potential for energy production through solar energy, and the country has a large solar potential that can be used. Thus, this work focuses on the study of the reliability of charging electric vehicles through photovoltaic energy, being sized electric vehicles charging stations, with different topologies, for domestic consumption, for different types of user profiles. At the same time this study evaluated technically and economically the proposed solutions. The research concluded that this type of technology proves to be a viable solution, especially if storage systems do not need to be implemented, as the limited useful lifetime of batteries substantially increases investment amortization times.

The primary constraint of photovoltaic (PV) systems is the relatively low conversion efficiency of PV panels (PVPs), heavily influenced by their operating temperature and sun irradiation under various configurations. The lack of precision in accounting for PV panel temperature and solar irradiation levels heightens the financial risk associated with system installation. This study examines the impact of solar irradiation, under constant temperature conditions 25OC, on a monocrystalline PV panel under standard test conditions (STC) of Ilorin, North Central Nigeria. The output performance of a specific PV panel model was initially investigated by simulating it using the Scilab Xcos™ software. The current-voltage (I-V) and power-voltage (P-V) curves are utilized to evaluate the performance of PV panels, taking into account the temperature of the panels and varying solar irradiation levels. The simulation's findings demonstrate that when solar irradiation varies from 400 W/m2 to 1000 W/m2, there is a linear increase in both the open circuit voltage (Voc) and short circuit current (Isc). The amount of solar irradiance causes this linear increase. The results also revealed that the quantity of irradiation the PV modules are able to extract directly relates to the PV module's output power. Furthermore, the current and voltage reached their peak levels of 7.12 A and 15 V, respectively, when the solar radiation intensity was 1000W/m^2. Their minimum values were 2.95 A and 14 V, respectively, when exposed to a solar radiation of 400W/m^2. The power output of the photovoltaic (PV) panel grew in direct proportion to the rise in solar radiation. Specifically, the power output declined to 85.95 W when the solar radiation was 400W/m^2, while it was 223.64 W when the solar radiation was 400W/m^2.

Oleh karena itu, penulis menyarankan kepada pengembang dan peneliti selanjutnya untuk dapat mengembangkan aplikasi secara lebih luas. Abstract: New Student Admission is an activity to admit new students in schools. No exception Bina Khalifah Bangsa Islamic Vocational School also conducts the process of accepting new students in January - May. Based on observations and interviews with the school, SMK IB Khalifah Bangsa still registers new students manually, namely prospective new students must come to school to get new information and register. Given this problem, the purpose of this research is to design a website-based information system using the Software Development Life Cycle (SDLC) method and testing using Black Box Testing. The result of this research is a website with the address https://smkib.com, which can simplify the process of data management, report generation, and acceptance of students in schools. The drawback of this website is that the application is still online and web based. Therefore, the authors suggest to developers and further researchers to be able to develop applications more broadly.

Cal Donat membuat list kebutuhan gerai dengan menginput data produksi di file.xls yang berbeda setiap harinya. Hal tersebut mengakibatkan banyaknya kendala yang terjadi seperti: file yang tidak dapat dibuka, selalu membuat file baru untuk menginput data produksi, terdapat banyak file yang tersimpan, sulitnya menganalisa dan memprediksi data, harus membuka banyak file untuk melihat perbedaan kebutuhan dan kendala-kendala lainnya. Dengan demikian penulis melakukan analisis data yang berfokus pada salah satu gerai Cal Donat yaitu Cal Donat Husada dengan data roti manis dan minuman. Analisis ini akan menggunakan teknik pengolahan data atau data mining dengan metode association rule dan apriori sebagai algoritma untuk mencari keterkaitan antar item dan mendapatkan rules atau aturan yang dapat menyelesaikan permasalahan yang ada di Caldonat Husada. Hasil yang diperoleh yaitu terbentuknya 3 itemset yang terdiri dari: 1; 2; 5 yang dapat didefinisikan sebagai berikut: (1 = Keju; 2 = Coklat; 5 = Pisang Keju) dengan minimum support 70%, maka Nilai Confidence dapat diperhitungkan. Uji coba untuk Nilai Confidence yaitu 70%, dari 3 itemset yang terdiri dari (1 = Keju; 2 = Coklat; 5 = Pisang Keju), maka terbentuknya 6 pola perhitungan confidence. Dari nilai confidence yang sudah terbentuk, maka dapat dihitung nilai lift ratio yang menunjukkan bahwa Lift Ratio > 1, maka hubungan positif yang dimaknai [Coklat, Pisang Coklat] dan [Keju] lebih sering muncul bersamaan

Abstrak : Pelaksanaan posyandu di Kampung Tanggulangin sudah berjalan dengan baik namun, permasalahan di bidan desa dan kader di mana pada proses pemberitahuan jadwal kegiatan posyandu dan pada estimasi kehadira peserta posyandu. Pada penyampaian informasi jadwal kegiatan posyandu kader masih menggunakan cara manual yaitu dengan cara memberi tahu masyarakat sekitar dengan datang ke rumah orang tua balita ataupun melakukan pengumuman dengan pengeras suara di majid atau mushola. Hal tersebut memakan waktu karena jarak rumah kader ke masjid atau mushola dan jarak rumah kader ke peserta posyandu lumayan jauh, dan penyampaian informasi jadwal kegiatan posyandu dengan metode pengumuman menggunakan pengeras suara di masjid sering membuat terjadinya kesalahan informasi. Dan ketika ingin diadakan suatu kegiatan seperti imunisasi atau PMT (Pemberian Makanan Tambahan), estimasi kehadiran juga sangat di butuhkan untuk mempermudah bidan mengetahui perkiraan stok obat vaksin imunisasi dan PMT yang akan di bagikan. Tujuan dari penelitian ini adalah untuk Merancangan Sistem Informasi Penjadwalan Kegiatan Posyandu Berbasis Web Pada Poskesdes Kampung Tanggulangin Punggur. Metode yang di gunakan yaitu metode kualitatif, metode pengembangan perangkat lunak, sistem informasi penjadwalan kegiatan posyandu berbasis web pada poskesdes kampung Tanggulangin Punggur menggunakan metode SDLC serta pengujian menggunakan teknik BlackBox Testing. Hasil dari penelitian ini adalah menghasilkan sebuah website yang didalamnya mencakup sebuah informasi lengkap mengenai Posyandu di Poskesedes Kampung Tanggulangin, informasi penjadwalan dan estimasi kehadiran peserta posyandu.

Mengantuk saat berkendara menjadi ancaman serius yang dapat meningkatkan risiko kecelakaan, yang merupakan penyebab utama kematian di seluruh dunia, termasuk di Indonesia. Deteksi dan pencegahan kondisi mengantuk pada tahap awal menjadi krusial untuk mengurangi potensi kecelakaan dan meningkatkan keselamatan berkendara. Penelitian ini fokus pada pemanfaatan citra wajah pengemudi sebagai metode efektif dalam mendeteksi mengantuk. Rendahnya kontras dalam citra dapat mempengaruhi deteksi wajah, sehingga diperlukan peningkatan kontras citra. Dalam penelitian ini, dua teknik peningkatan kontras citra, yaitu Histogram Equalization (HE) dan Adaptive Histogram Equalization (AHE), dievaluasi. Dataset yang digunakan adalah Driver Drowsiness Dataset, terdiri dari citra Drowsy sebanyak 22,348 dan Non-Drowsy sebanyak 19,445. Pra-pemrosesan melibatkan resize dan pengaburan menggunakan Gaussian Blur, diikuti oleh penerapan HE dan AHE. Evaluasi kinerja dilakukan menggunakan matriks evaluasi, menghasilkan skor Mean Squared Error, Peak Signal-to-Noise Ratio, dan Signal-to-Noise Ratio. Hasil menunjukkan bahwa HE memberikan hasil yang lebih baik dengan skor MSE 101.21, PSNR 28.11, dan SNR 0.19, dibandingkan dengan AHE yang memiliki skor MSE 103.92, PSNR 27.97, dan SNR 0.04. Oleh karena itu, dapat disimpulkan bahwa HE memberikan peningkatan kontras yang lebih baik untuk citra wajah dibandingkan dengan AHE.
