Energi listrik yang mampu dibangkitkan oleh photovoltaic (PV) sangat dipengaruhi oleh faktor-faktor eksternal seperti intensitas iradiasi matahari, suhu lingkungan dan orientasi sudut kemiringan dari pemasangan PV. Intensitas iradiasi matahari di permukaan bumi selalu berubah-ubah nilainya seiring dengan pergerakan matahari di langit mulai matahari terbit sampai terbenam. Pada makalah ini akan dibahas PV solar tracker dengan reflektor cermin datar untuk mendapatkan intensitas iradiasi matahari yang maksimal sepanjang hari. Penggunaan reflektor dalam makalah ini bertujuan untuk meningkatkan diffuse irradiance dan memperpendek jarak tempuh pergerakan solar tracker sehingga lebih hemat energi. Solar tracker didesain bergerak otomatis mengikuti posisi matahari dengan memperbarui sudut solar tracker sesuai sun hour angle (sudut jam matahari) secara periodik 1 jam sekali. Penentuan sudut solar tracker dikontrol oleh mikrokontroler ATMega16. Hasil percobaan lapangan diperoleh daya yang mampu dihasilkan PV menggunakan solar tracker dengan reflektor cermin datar setiap jamnya mengalami kenaikan daya rata-rata sebesar 76.05% dibandingkan dengan PV terpasang statis. Secara komulatif dalam satu hari energi didapatkan posentase kenaikan energi dapat mencapai 75.20% dibandingkan dengan PV yang dipasang secara statis. Sedangkan konsumsi energi untuk menggerakkan solar tracker memerlukan energy kurang dari 0.15% dari total energi yang mampu dihasilkan oleh PV.

Battery is one of the important components in the development of renewable energy technology. This paper presents a method for estimating the State of Charge (SoC) for a 4Ah Li-ion battery. State of Charge (SoC) is the status of the capacity in the battery in the form of a percentage which makes it easier to monitor the battery during use. Coulomb calculations are widely used, but this method still contains errors during integration. In this paper, SoC measurement using Open Circuit Voltage Compensation is used for the determination of the initial SoC, so that the initial SoC reading is more precise, because if the initial SoC reading only uses a voltage sensor, the initial SoC reading is less precise which affects the next n second SoC reading. In this paper, we present a battery management system design or commonly known as BMS (Battery Management System) which focuses on the monitoring function. BMS uses a voltage sensor in the form of a voltage divider circuit and an ACS 712 current sensor to send information about the battery condition to the microcontroller as the control center. Besides, BMS is equipped with a protection relay to protect the battery. The estimation results of the 12volt 4Ah Li-ion battery SoC with the actual reading show an error of less than 1%.Keywords: battery management system, modified coulomb counting, state of charge

The air conditioning system that is commonly used today is an Air Conditioner (AC). Unfortunately, this system is a big contributor to global warming. Often times, we find that air conditioners are only used to cool only a small part of a room for individual comfort. Therefore, a new breakthrough is needed from a cooling system that does not use chemicals so that it is environmentally friendly, namely using the Thermo Electric Cooler (TEC) cooling module which utilizes the cold side of the Thermo Electric Cooler (TEC). The size of the DC input voltage on the Thermo Electric Cooler (TEC) is adjusted using a buck converter with fuzzy control. When the buck converter closed loop condition with fuzzy control has a rise time value, the settling time and error percentage have a relatively better value than the open loop condition. When the buck converter set point 40V, the minimum water temperature in the air cooler can be reached 220C, when the buck converter set point is 48V the minimum water temperature in the water cooler can be reached 190C, and when the buck converter set point is 56V the minimum water temperature in the air cooler can be reached 180C. When the water cooler uses air cooler by Peltier, the input air temperature and output air temperature decrease in temperature around 10C. this is caused by the evaporative effect caused by water cooled by the peltier.Keywords: buck converter, cooler, fuzzy, thermo electric cooler.

Medicines should be stored in a room at a suitable temperature because the condition of temperature affects the quality of the drug. Improper storage procedures may result in the drug being unable to cure effectively and cause drug damage which results in losses for pharmaceutical industry companies and patients. Therefore a controller for temperature is needed in the room so that it is constantly under the rules of room temperature for drug storage, which is 25 degrees Celsius. The following paperwork presents a simulation controller between PI controller and PI-Fuzzy logic controller in adjusting the voltage to match the set of points. The fuzzy logic controller automatically searches Kp value so the voltage output of the converter matches the desired set of points. The converter used is a synchronous boost converter as a voltage regulator and Peltier as a DC load which functions as a cooler. In this research, the system using PI controller was able to adjust the voltage to match the set point 60V with KP is 0.14089, Ki is 125.6738, and the settling time is 0.016 s. While the system using PI-Fuzzy logic controller, it was able to adjust the voltage to match the set point 60V with Kp is 0.08112, Ki is 125.6738, and settling time is 0.014 s. It can be concluded that the PI Fuzzy controller can find the KP value automatically and reach the desired set point.

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.

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.

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.

A new maximum power point tracking (MPPT) technique based on the bio-inspired metaheuristic algorithm for photovoltaic system (PV system) is proposed, namely tunicate swarm algorithm-based MPPT (TSA-MPPT). The proposed algorithm is implemented on the PV system with five PV modules arranged in series and integrated with DC-DC buck converter. Then, the PV system is tested in a simulation using PowerSim (PSIM) software. TSA-MPPT is tested under varying irradiation conditions both uniform irradiation and non-uniform irradiation. Furthermore, to evaluate the performance, TSA-MPPT is compared with perturb & observe-based MPPT (P&O-MPPT) and particle swarm optimization-based MPPT (PSO-MPPT). The TSA-MPPT has an accuracy of 99% and has a reasonably practical capability compared to the MPPT technique, which already existed before.

The inverter has been attracting researchers for their application in renewable energy. So far, multilevel inverter is considered as low distortion class, which produces multilevel output voltage imitating a pure sine waveform. However, the needs for free distortion of output voltage have been motivating to improve multilevel pulse width modulation PWM generation method. In this paper, the modified PWM technique is proposed to reduce the voltage total harmonics distortion (THD) of multilevel inverter. This modulation technique is then applied to control a single-phase threelevel neutral point clamped multilevel inverter (NPC-MLI). Grey wolf optimizer (GWO) algorithm is utilized to generate optimal amplitude and phase shift of modified reference signal. The GWO algorithm is then compared with other optimization algorithms such as differential evolution (DE), human psychology optimization (HPO), and particle swarm optimization (PSO) to evaluate their performance in harmonic minimization. The performance of the proposed work is validated through simulation and experimentation on a prototype. The results show that the modified PWM technique optimized with GWO can reduce THD on NPC-MLI output voltage.
