Abstract

Kualitas keandalan jaringan distribusi sangat penting dalam menentukan kinerja sistem distribusi tenaga listrik. Dalam suatu jaringan distribusi, kualitas keandalan dapat dilihat dari lamanya pemadaman listrik dan seberapa sering terjadinya pemadaman listrik dalam kurun waktu tertentu. Sistem distribusi tentunya memiliki nilai keandalan, dimana indeks-indeks keandalan yang digunakan untuk menghitung nilai keandalan yaitu SAIDI dan SAIFI. Metode yang digunakan dalam menghitung indeks keandalan pada tugas akhir ini adalah menggunakan metode Reliability Netwok Equivalent Appoach (RNEA), dimana prinsip utama dari metode RNEA adalah elemen ekuivalen dapat digunakan untuk mengganti bagian jaringan distribusi dan menyusun kembali sistem distribusi yang besar ke dalam bentuk seri dan sederhana. Berdasarkan hasil yang diperoleh dari analisis pada penyulang Strawberry dan penyulang Nila, didapatkan nilai indeks keandalan untuk penyulang Strawberry yaitu, nilai SAIDI sebesar 9,2718 dan nilai SAIFI sebesar 3,0055. Penyulang Nila diperoleh nilai indeks keandalan SAIDI sebesar 13,8186 dan SAIFI sebesar 4,44104

Abstract

Abstrak. Artikel ini menyajikan analisis dinamik operasi islanding pada sistem tarahan dengan tingkat penetrasi PV yang tinggi. Dalam konteks ini, operasi islanding merujuk pada kondisi di mana sebagian dari sistem distribusi terisolasi dari jaringan utama setelah terjadi gangguan. Studi ini mengkaji berbagai skenario dan parameter yang mempengaruhi stabilitas dan keandalan operasi islanding dalam sistem tarahan yang didominasi oleh PV.  Metode analisis simulasi komprehensif digunakan untuk mengevaluasi dampak variabel seperti daya PV, konfigurasi jaringan, dan pengendalian aliran daya terhadap kestabilan sistem selama operasi islanding. Hasil analisis menunjukkan bahwa penetrasi PV yang tinggi dapat mempengaruhi dinamika operasi islanding secara yang signifikan, termasuk potensi masalah stabilitas frekuensi dan tegangan. Pengendalian aliran daya yang optimal dan penggunaan sumber daya baterai terdistribusi dapat menjadi solusi untuk mengatasi tantangan ini. Penelitian ini memberikan alternatif pertimbangan yang berharga bagi operator sistem tenaga listrik dan perancang sistem distribusi dalam menghadapi pertumbuhan penetrasi PV yang terus meningkat. Abstract- In this paper, dynamic analysis of islanding operation in the Tarahan system with a high PV penetration rate is presented. In this case, islanding operation refers to a condition where a portion of the distribution system is isolated from the main network after a fault occurs. This study examines various scenarios and parameters that affect the stability and reliability of islanding operations in the Tarahan system dominated by solar power plants.  A comprehensive simulation analysis method is used to evaluate the impact of variables such as PV power, network configuration, and power flow control on system stability during islanding operations. The results show that high PV penetration can significantly affect the dynamics of islanding operations, including potential frequency and voltage stability issues. Optimal power flow control and the use of distributed battery resources can be solutions to address these challenges. This research provides important alternative considerations for power system operators and distribution system designers in the face of growing PV penetration

Abstract

Pembangkit listrik di Indonesia saat ini masi bergantung pada energi fosil, yang mana ketersediannya semakin terbatas, sehingga diperlukannya sumber energi listrik yang berasal dari energi terbarukan salah satunya yaitu PLTS. Dengan adanya pembangkit energi baru dan terbarukan efeknya dapat mengurangi penggunaan energi fosil sekaligus mengurangi emisi karbon yang ada. Pada PLTS perlu dilakukannya pengukuran nilai tegangan dan arus agar dapat mengetahui daya yang dapat dihasilkan. Jika pengukuran dilakukan secara manual dan harus dilakukan secara terus menerus maka tidak akan efektif dan efisien dalam penggunaannya. Sehingga berdasarkan hal tersebut, perlu dibuat alat sistem pemantauan tegangan, arus, dan daya pada panel surya. Penelitian ini bertujuan untuk mengembangkan protoype sistem pemantauan panel surya berbasis IoT. Berdasarkan percobaan protoype sistem pemantauan panel surya yang dibuat dapat bekerja dengan baik dan hanya memiliki nilai rata-rata error sebesar 0,56% untuk tegangan dan 7% untuk arus.

Abstract

PV systems has an important role in compliance of electrical demand. PV systems depends on sunlight intensity so that the PV output is nonlinear, this is a challenge in the control system design of PV system can maintain voltage and frequency stability. The P&O method based MPPT is applied to get the maximum power output of PV. The PWM control inputs are a reference Id from the MPPT and the voltage and current from the grid tied with Phase Looked Loop (PLL) for synchronization PV inverter. The control scheme given can provide stability voltage on the load against to the radiation changes that occur in PV

Abstract

Bad weather often interferes with the functioning of the air transport system. One example is the frequent flight delays for commercial aircraft, resulting in losses for both the airline and passengers. Artificial Intelligence (AI) technology can now minimize delays caused by bad weather, especially in low visibility conditions. This paper discusses AI modeling that can detect aircraft in a low visibility weather condition, especially in the airport area. The employed method is the deep learning approach with the YOLOv4 algorithm (single-stage detection), which is regarded as one of the optimal platforms in this field. There are 600 images used in this work to create and train three different models. Image Dehazing filter is employed on the training data before it is trained to produce the detection model. The result shows that the model has a good performance in terms of performance metrices. Thus, this model is suitable to be used to detect aircraft in low visibility conditions.

Abstract

As aircraft industries contribute more than 12% of the carbon emission globally, the urgency to develop a more sustainable and reliable source of energy to power aircrafts has become greater. Regarding that concern, an electric-powered aircraft is proposed to become the solution for the search of green technology. An electric aircraft has been proven to be capable of reducing carbon emission and sound emission. Despite of the advantages, the use of electric aircraft is still very scarce since there are a lot of considerable issues such as low energy density power sources, reliability problems, and the lack of design references. As a contribution for the development process, an electric aircraft by the name of “Djinn” has been designed, in hope that this aircraft can be an addition to the references for future endeavors. The methods used for designing the aircraft is similar as the methods used for developing conventional aircrafts, with slightly modified approximation and assumptions.
