PT. PLN (Persero) merupakan Badan Usaha Milik Negara (BUMN) yang bergerak dibidang pembangkitan dan pendistribusian tenaga listrik bagi seluruh masyarakat Indonesia. Pada proses distribusi sering terjadi gangguan hubungan singkat yang diakibatkan banyak faktor diantaranya faktor eksternal atau faktor alam yang berupa ranting pohon maupun hewan. Dari data pada sebuah wilayah Unit Pelaksana Pelayanan Pelanggan (UP3) dalam sebulan gangguan bisa terjadi hingga 70 kali dan memerlukan waktu penanganan 15 menit hingga 1 jam. Karena penanganan masih dengan cara mengukur impedansi sepanjang jaringan yang dimana sebuah penyulang bisa memiliki panjang hingga 50 kms. Oleh karena itu dibutuhkan alat yang dapat mendekteksi titik gangguan serta jenis gangguan yang terjadi pada jaringan. Untuk merealisasikan alat tersebut diperlukan prototype jaringan tegangan menengah yang dapat mensimulasikan gangguan hubung singkat satu fasa ke tanah, dan antar fasa. Prototype ini menggunakan mikrokontroler yang akan difungsikan sebagai relay over current dan saat ada gangguan hubung singkat mikrokontroler juga akan langsung melakukan perhitungan lokasi gangguan dari relay yang trip berdasarkan besar arus gangguan yang dideteksi oleh relay. Pada alat ini terdapat LCD yang digunakan untuk menampilkan besar arus gangguan serta jenis gangguan yang terjadi dan diharapkan dapat mempermudah serta mempercepat petugas untuk melakukan penormalan kembali pada jaringan yang mengalami gangguan.

Dengan perkembangan konverter elektronika daya, kebutuhan untuk memperkecil ukuran dan keandalan semakin meningkat. Dengan meningkatnya frekuensi switching pada konverter, maka dv/dt yang tinggi dapat menyebabkan kesalahan dalam turn-on ataupun turn-off switching devices. Masalah-masalah tersebut dapat diatasi dengan menerapkan tegangan bias negatif untuk melakukan turn-off switching devices. Makalah ini mengusulkan prototipe power supply gate driver yang dikhususkan untuk Multi Level Inverter (MLI). Sebuah prototipe power supply gate driver yang menggunakan satu unit konverter flyback dengan multi output untuk tegangan bias positif dan negatif, serta terisolasi galvanis sebanyak switching devices MLI. Dengan menggunakan topologi dasar flyback maka konverter ini memiliki isolasi galvanis melalui trafo frekuensi tinggi. Dari hasil eksperimen proses switching bisa berubah dari kondisi dari on menuju off dan dari off menuju on bisa berjalan secara sempurna.

“Sumber Air Surupan” Dusun Bolo Desa Kebon Agung Kecamatan Kebon Agung Kabupaten Pacitan adalah satu daerah di atas perbukitan dengan jarak 15 km dari pusat kota Pacitan. Warga Dusun Bolo Desa Kebon Agung yang paling puncak warga memanfaatkan sumber air yang berada dibagian paling bawah dari jalan yang biasa dilewati sehingga air dari bawah diambil secara manual menggunakan alat seadannya dan dibawah keatas dengan jarak yang cukup jauh dan curam sehingga diperlukan tenaga yang cukup besar dalam proses pengambilan air, sehingga kami memilih daerah tersebut yang kami anggap sangat membutuhkan dan paling cocok untuk aplikasi dari sistem PV dan penyimpanan energi yang kami kembangkan selama ini untuk pengabdian kepada masyarakat. Kami berkolaborasi dengan AKN Pacitan untuk merealisasikan sistem PV dan penyimpan energi ini. Sebelumnya melalui dana pengambdian masyarakat tahun 2020 telah melakukan implementasi pemanfaatan energy baru terbarukan menggunakan PV ini di Dusun Puguh RT 20 / RW 10, Desan Gondosari Kecamatan Punung Kabupaten Pacitan. Namun, sistem yang dipasang saat itu baru mampu bertahan selama satu hari saja jika tidak ada cahaya matahari/pada saat kondisi mendung karena keterbatasan kapasitas sel surya (PV) dan baterai yang dipasang.

Due to natural randomness, partial shading conditions (PSCs) to photovoltaic (PV) power generation significantly drop the power generation. Metaheuristic based maximum power point tracking (MPPT) can handle PSCs by searching PV panels’ global maximum power point (GMPP). However, trapped at local maxima, sluggishness, continuous power oscillations around GMPP and inaccuracy are the main disadvantages of metaheuristic algorithm. Therefore, the development of algorithm under complex PSCs has been continuously attracting many researchers to yield more satisfying results. In this paper, several algorithms including conventional and metaheuristic are selected for candidate, such as perturb and observe (P&O), firefly (FF), differential evolution (DE), grey wolf optimizer (GWO) and Seagull optimizer (SO). From the preliminary study, SO has shown best performance among other candidates. Then, SO is improved for rapid global optimizer. Modified variable step sizes perturb and observe (MVSPO) is applied to enhance the accuracy tracking of SO. To evaluate the performances, high complexity multipeak partial shading is used to test the algorithms. Statistical results are also provided to analyze the trend of performances. The proposed method performances are shown better fast-tracking time and settling time, high accuracy, higher energy harvesting and low steady-state oscillations than other candidates.

The use of lighting loads is one of the crucial matters which increases every year. The increasing use then leads to the development of brighter and longer-lasting sources. In addition, the conventional use of lighting loads today, which only emit light at its maximum intensity, does not allow the consumers to adjust the brightness level as needed. Consequently, this condition may cause energy wastage. The LED lighting system is gaining popularity as it is widely used in a wide range of applications. The advantages of LEDs, such as its compact size and varied lamp colors, replace conventional lighting sources. The linear setting of the driver topology using the flyback converter was aimed to control the LEDs with a constant current in order to adjust the variation of the LED light intensity. The closed-loop driver circuit with flyback converter topology was designed as an LED driver with a given load specification from the LED string. A dimmable feature was included for adjusting the intensity of the light produced by the LEDs. Eventually, the fuzzy logic controller (FLC) method was applied to the integrated change setting to obtain a dynamic response.

Pengendali suhu air sangat dibutuhkan dibeberapa industri dan gedung komersil. Pemanas air elektrik umumnya hanya dapat memamanaskan air dan tanpa adanya kendali suhu, salah satunya adalah peralatan komersil dispenser air minum. Penelitian ini penulis mengusulkan pengaturan suhu air panas pada dispenser yang dapat diatur dengan pengendalian Propotional-Integral (PI) dengan metode tunning Ziegler-Nichols I, Chien Servo I, dan Chien Regulator I dengan dua nilai setpoint yaitu pada suhu 80°C atau di suhu 90°C. Sensor yang digunakan adalah RTD PT100 sebagai sensing suhu air panas pada tabung dispenser. Hasil penelitian menunjukkan bahwa suhu air panas dapat stabil di masing-masing setpoint tersebut dengan ketiga jenis penalaan kontrol PI. Metode Chien Regulator I memiliki rise time yang lebih cepat dan memiliki kestabilan yang baik dibandingkan dengan kedua metode lainnya dengan besarnya error steady state di bawah 2%.

The development of power electronics converters has been widespread in the industrial, commercial, and home applications. The device is considered to produce harmonics in non-linear loads. Harmonics cause a decrease in power quality in the electric power system. To prevent a decrease in power quality caused by harmonics in the power system, the detection of harmonics has an important role. Therefore, this paper proposed feed forward neural network (FFNN) for harmonic detection. The design of harmonic detection device is designed with a feed forward neural network method that it has two stages of information processing, namely the training stage and the testing stage. FFNN has input harmonics and THDi as output. To detect harmonics, frst training is conducted to recognize waveform patterns and calculate the fast fourier transform (FFT) process ofﬂine. Prototype using the AMC1100DUB current sensor, microcontroller and display. To validate the proposed algorithm, compared by standard measurement tool and FFT. The results show the proposed algorithm has good performance with the average percentage error compared by standard measurement tool and FFT of 5.33 %.

The battery balancing method is commonly used in cell circuits and battery circuits to maintain the power continuity on the DC Bus. The power continuity on the DC Bus is guaranteed if the load continues to get a power source, even if either the battery or power supply malfunctions. Besides, the battery balancing method is also used to protect the battery from excessive charging current pliers flowing into the battery. Therefore, the State-of-Charge (SoC) should be concern in balancing the maintained battery condition on both systems and avoiding overcharging. Artificial Neural Network (ANN) is used in this paper to determine the value of battery SoC. Based on simulations using MATLAB 2018, SoC values with ANN showed accurate results with error values below 0.1%. Based on the simulation results, the two batteries, which are arranged to have a difference of SoC value of 0.3%, will achieve a balanced SoC value for 28.45 seconds from the simulation.

In the modern era, AC voltage variations are still often a problem. This variation causes power quality decrease even damage the equipment. Voltage variations that often occur are short and long duration. The variation consist of 6 types namely Interruption, Sag, Swell, Sustained-Interruption, Undervoltage, Overvoltage. To facilitate repairs when there is a voltage variation in the electric power system, it is necessary to have an identification that can detect and distinguish any interference that occurs. Therefore, this paper proposes a fuzzy logic method for identifying types of voltage variations. This type of voltage variation identifier requires a disturbance simulator as a voltage source with varying values. To distinguish between short duration and long duration disturbances, is the time duration of the disturbance appears. The design of the voltage variation identification algorithm uses the sugeno fuzzy inference system with 2 inputs namely magnitude vrms and timer, and 1 output is the type of voltage interference. Moreover, prototype design using AMC1200 voltage sensor, microcontroller, and display. To validate the proposed algorithm, compared with standard measuring tools and simulations. Results show that the proposed algorithm has a very good performance with an accuration compared to the standard measuring instrument of 99.8%.

This paper describes a low-cost solar panel simulator for Maximum Power Point Tracking (MPPT) method testing, especially under partially shading conditions. The simulator consists of a DC power supply and a solar panel. The simulator works to emulate the characteristics of solar panels without depending on artificial illumination or sunlight. The simulator can represent the needed irradiation through the settings on the DC power supply. The experimental setup is developed to emulate the characteristics of solar panels at Standard Test Conditions (STC) irradiation conditions as well as varying irradiation conditions. Testing is done to emulate irradiation varies from 200-1,000 W/m2. To emulate the characteristics of solar panels in partial shading conditions, two DC power supply units and two solar panels are used. Each solar panel is simulated to receive different solar irradiations. The test results show that the simulator can emulate the characteristics of solar panels under partial shading conditions which has several maximum power points. Furthermore, partial shading conditions are simulated under varying irradiation conditions which resulted varying maximum power point values.
