Abstract

This paper proposes a novel control strategy for enhancing power quality through the implementation of an Interval Type-2 Fuzzy Logic Controller (T2FLC) for Shunt Active Power Filters (SAPF). The presented method effectively addresses harmonic distortions introduced by non-linear loads, a common issue in modern electrical systems. Extensive simulations conducted in MATLAB/Simulink demonstrate the T2FLC's ability to regulate the DC bus voltage while significantly reducing Total Harmonic Distortion (THD). The method achieves superior performance compared to both traditional passive and active filtering techniques, reducing THD within the limits specified by IEEE 519-2014 standards. The results confirm the robustness and adaptability of the proposed approach across varying load conditions, establishing it as a reliable and scalable solution for improving power quality in complex electrical networks.

Abstract

The number of academic publications in the building-integrated photovoltaics (BIPV) field has rapidly grown. Most published articles focus on a specific topic, such as mathematical model, solar architecture design, photovoltaic effect, solar cell, grid-connected, efficiency, performance assessment, economic analysis, optimization, and others with broader focus areas. This work focuses on BIPV research with bibliometric analysis through documents, cited references, authors, affiliations, countries, funding sponsors, sources, words, and conceptual structure based on the Scopus-indexed database between 1971 and 2022. The result shows that BIPV research constantly grows annually with strong collaboration authorship. China is the most relevant country with the top affiliation and funding sponsor to support the BIPV research. The terms conjugated polymers, photovoltaic properties, and organic polymer are identified as niche themes. On the other hand, the terms of conversion efficiency, perovskite, photovoltaic devices, solar cells, efficiency, and photoelectrochemical cell clusters are emerging themes. In the future, BIPV research will move towards microgrids, energy, performance, energy management systems, and energy efficiency issues. The finding will also provide researchers and organizations with a comprehensive understanding of BIPV research areas and new directions for future research.

Abstract

The utilization of solar energy through photovoltaic (PV) systems continues to face efficiency challenges due to variations in light intensity and the sun’s changing position throughout the day. Static PV panels perform optimally only when positioned perpendicular to incoming sunlight, necessitating an adaptive tracking mechanism. This study designs and evaluates a low-cost dual-axis active solar tracking system employing light-dependent resistors (LDRs) and an Arduino Uno microcontroller to automatically adjust the panel’s orientation in response to solar movement. A five-day performance test was conducted comparing the dual-axis tracker with a fixed-panel system, measuring output power, voltage, current, and overall efficiency. Results show an average power increase of 7.41 W and an efficiency gain of 1.63% with the tracking system. A peak efficiency of 13.49% was recorded under low irradiance conditions, indicating the system’s ability to maintain optimal performance despite fluctuating light. These findings suggest that dual-axis tracking offers a practical and effective solution for enhancing PV efficiency, especially in regions with significant daily variations in solar intensity.Pemanfaatan energi surya melalui sistem fotovoltaik (PV) masih menghadapi tantangan efisiensi akibat variabilitas intensitas cahaya dan posisi matahari sepanjang hari. Panel PV statis hanya menghasilkan daya maksimum saat tegak lurus terhadap arah sinar matahari, sehingga diperlukan sistem pelacakan yang adaptif. Penelitian ini merancang dan menguji sistem pelacak surya aktif dua sumbu berbiaya rendah dengan menggunakan sensor light-dependent resistor (LDR) dan mikrokontroler Arduino Uno, yang secara otomatis mengatur orientasi panel mengikuti pergerakan matahari. Pengujian dilakukan selama lima hari untuk membandingkan kinerja sistem pelacak dengan panel statis, menggunakan parameter daya keluaran, tegangan, arus, dan efisiensi. Hasil menunjukkan peningkatan daya rata-rata sebesar 7,41 W dan efisiensi sebesar 1,63% pada sistem pelacak. Efisiensi tertinggi sebesar 13,49% dicapai pada kondisi iradiasi rendah, mengindikasikan kemampuan sistem dalam menjaga performa optimal di bawah pencahayaan yang tidak stabil. Temuan ini menunjukkan bahwa pelacak dua sumbu merupakan solusi praktis dan efektif dalam meningkatkan efisiensi sistem PV, terutama di wilayah dengan fluktuasi harian intensitas surya yang signifikan.

Abstract

Indonesia memiliki kepadatan sambaran petir yang tinggi, sehingga petir menjadi salah satu penyebab gangguan pada sistem ketenagalistrikan. Salah satu upaya untuk menjaga keandalan sistem transmisi dari petir adalah dengan menggunakan Lightning Arrester (LA) di gardu induk. Penting untuk mengetahui dan mendeteksi sejak dini penurunan kinerja LA dikarenakan peralatan sistem ketenagalistrikan yang beroperasi tanpa henti. Hal ini dapat dilakukan dengan menganalisis hasil uji thermovisi dan leakage current measurement (LCM) yang termasuk dalam inspeksi level 2 (online maintenance). Penelitian ini bertujuan untuk menganalisis hubungan antara thermovisi dan LCM terhadap kelayakan operasi LA sebagai pengaman terhadap petir dengan objek penelitian yaitu LA pada Bay Sukaluyu 1 & 2 di Gardu Induk Cianjur. Dari hasil analisa didapatkan bahwa berdasarkan thermovisi dan LCM LA Bay Sukaluyu 1 phasa R dan T, serta LA Bay Sukaluyu 2 phasa R, S, dan T masuk kategori layak operasi dikarenakan tidak ditemukan adanya perbedaan warna mencolok pada thermovisi dan persentase kondisi LA masih dibawah 90%, sedangkan untuk LA Bay Sukaluyu 2 phasa S masuk dalam kategori tidak layak operasi dikarenakan ditemukan adanya perbedaan warna mencolok pada thermovisi dan persentase kondisi LA melebihi 90%.

Abstract

Sistem tenaga listrik meliputi pembangkit, transmisi (gardu induk dan saluran transmisi), serta distribusi. Gardu induk yang terhubung melalui saluran udara sering mengalami gangguan permanen atau temporer. Pada bay penghantar Bandung Selatan 2 di GISTET Saguling, terjadi gangguan temporer yang menyebabkan Pemutus Tenaga (PMT) 7A3 berhasil diaktifkan kembali oleh relay auto recloser, sedangkan PMT 7AB3 gagal beroperasi. Penelitian ini bertujuan untuk menginvestigasi gangguan pada bay penghantar Bandung Selatan 2 dan menganalisis kegagalan relay auto reclose PMT 7AB3. Analisis mencakup verifikasi kesesuaian antara pengaturan standar dan data setting pada relay serta pemeriksaan Programmable Scheme Logic (PSL). Troubleshooting dilakukan dengan memodifikasi program PSL, yaitu memutuskan hubungan masukan L5 AR BLK 7AB dari keluaran Block CB2 AR, sehingga fungsi AR Block tidak aktif. Langkah ini bertujuan untuk memastikan relay auto reclose dapat memberikan perintah agar PMT 7AB3 dapat diaktifkan kembali. Hasil analisis dan troubleshooting ini diharapkan dapat memperbaiki kinerja sistem proteksi dan memastikan kelancaran penyaluran energi listrik di masa mendatang.
