Abstract

Pembangkit Listrik Tenaga Surya (PLTS) Off-Grid memanfaatkan cahaya matahari untuk mengisi baterai, namun jika baterai penuh maka energi terbuang. Oleh karena itu, PLTS On-Grid dengan Grid Tied Inverter (GTI) dapat dimanfaatkan untuk mengurangi tagihan listrik dari PLN dengan menggunakan energi listrik Solar PV pada siang hari dan listrik PLN pada malam hari. Faktor radiasi matahari berpengaruh pada daya output, power factor dan efisiensi GTI. Energi yang tidak terpakai akan dijual ke PLN dengan nilai kWh tertentu. Gelombang arus GTI rentan mengalami ripple noise sehingga berpotensi memiliki nilai harmonisa yang tinggi. Efisiensi rata-rata Solar PV, Buck Converter, dan GTI adalah 6,13%, 94,32%, dan 68,1% secara berurutan, dan radiasi matahari serta kualitas komponen mempengaruhi efisiensi GTI.

Abstract

Automatic transfer switches (ATS) have the potential to be important in ensuring uninterruptible power supply across a wide range of sectors, enabling smooth transitions between utility and emergency RES power sources, generators, and more. Utilizing DC electricity provides a cost advantage and is suitable for short-distance transmission. The author proposes a 12-volt DC backup system that corresponds to a minimum input voltage of more than 10 Vdc and can be applied in various DC load applications. The ATS design incorporates multiple inputs and uses algorithms to prevent simultaneous operation of all sources and reduce feedback. These developments in backup system technology, coupled with the shift to renewable energy, are contributing to the creation of a sustainable and resilient electricity grid. In experiments, the ATS system demonstrated its ability to provide 24 hours of backup power with a specified load (lighting bulbs, light-emitting diodes (LEDs), motors, and fans) discharging 0.27–2.25 Amperes. Using the millis programming language, it supports the performance of a constant switch transition speed of around 0.6453 seconds for a switch from buck to SCC. 0.658 seconds for solar charge controller (SCC) to power supply (PSU), 0.656 seconds for PSU to CC PSU, and 0.61 seconds for PSU to OFF.

Abstract

VAWT (Vertical Axis Wind Turbine) is a turbine that has an upright mechanical structure with its blades rotating toward a perpendicular z-axis. Based on the experimental results, it is found that there is a relationship between the rotational speed of turbine that rotates generator with the output voltage and power. Thus, it is necessary to control the wind turbine speed so it can rotate according to the set point to be achieved. The contribution of this research is the development of a Fuzzy logic-based control system to control the speed of VAWT turbine where the speed of turbine is used as feedback. To design a Fuzzy rule base, the characteristics of the wind turbine’s response to wind speed are investigated first. Then Fuzzy logic-based controller is created and implemented. To test the effectiveness of the Fuzzy controller made, the implementation is carried out on a VAWT turbine while the simulation is applied to PMSG model using wind turbine through Simulink/Matlab. Based on simulation and experiment results, the performance of the control system using Integral Absolute Error (IAE) for each turbine speed set point value (35, 45, 85, and 100 RPM), it is found that for a small set point value, the IAE value will be larger than higher setpoints. The percentage of the average IAE value for the simulation is 10.25% higher than the experiment. It further shows that the control turbine speed at low speeds is relatively more difficult than at higher speeds.

Abstract

One of the technologies of this power source is a brine battery. In this study, testing the effect of electrolyte salinity levels on the performance of brine batteries with two different types of electrodes  was carried out, namely using magnesium anodes and aluminum anodes. In its cathode part used inert metal or carbon. Variations are carried out on the electrolyte solution used in the form of brine containing Na and Cl ions as electron conductors as well as reductors. Because the reaction of the brine battery system is relatively complex, a study was conducted in this study to see the effect of electrolyte salinity levels (27, 37, and 47 ppt) on the dc voltage produced. The measured parameters include the value of the dc voltage and the resulting current as well as the change in the salinity level after operating for a certain period of time. Tests were performed on batteries to drain the 0.47Ω resistor load operating for 24 hours non-stop where the parameter measurement setup was performed automatically using a PLC. The values of such parameters are monitored and recorded during 24-hour operation. Based on the results of measurements, the average energy capacity that can be used in Mg electrode cells is 17.6% of the total energy generated from the reaction of battery cells, then the average usable battery capacity on the Al electrode cell is 2.6% of the total energy produced.

Abstract

Automatic transfer switch (ATS) is useful for integrating two different energy sources can be applied to e-bike charging stations. Renewable energy sources from sunlight using 2×100 Wp photovoltaic (PV) modules as the main source in this study, as well as grid energy sources functioned as backup energy. This ATS uses inverter input rating methods and standard AC voltage drop/over, a novelty of this study. The amount of current during testing is up to 14.09 A. The value of the inverter input voltage affects the quality of the inverter output voltage, there is a stability of the inverter output voltage from the AC voltage standard ±5% of the, lowest voltage value of (Vo_inv) = 223.9 V and the highest value (Vo_inv) = 226.1 V, at the time of (Vi_inv) max = 14.15 V and (Vi_inv) min = 12.66 V. It can be concluded that the ATS works in the PV position of the supply to the e-bike load, in the PV state it can produce power of a maximum value of 135.9 W at 11:25 am and is at the lowest power of 31 W at 03:31 pm. This ATS device in the switch mode successfully implemented a duration range of 10-21 ms, during the transfer of energy.

Abstract

The internet of things (IoT) has become an important foundation in the development of web-based and remote technologies. In the implementation of renewable energy in hybrid E-bike systems, IoT-based monitoring system integration has made a significant contribution to monitoring activities. One of the latest innovations in the development of IoT in E-bike systems is the application of power prediction and the Coulomb counting method to estimate the charging time for a battery with a capacity of 200 AH, so that users can know the time needed to charge the battery efficiently. The IoT E-bike system is designed with user data display and monitoring features via the website, such as data on voltage, current, light intensity, battery percentage, power prediction, and prediction of the resulting battery charging time. Experimental results were obtained during the battery charging period, increasing the battery percentage from 50.43% (10 volts) to 71.769% (11.3 volts) in 4.5 hours with a battery charging charge of 153,866.4 C.

Abstract

Automatic control of temperature and humidity in greenhouses remains a critical challenge in precision agriculture, particularly in areas with limited access to modern technologies. This study aimed to design and implement an automated environmental control system using the DHT22 sensor and an Arduino microcontroller. The system was programmed to activate actuators, namely a water pump and a buzzer, based on predefined temperature and humidity thresholds. The research employed a hardware-based experimental method that included system programming, piping layout for water distribution, and field testing to validate sensor accuracy and control logic performance. The experimental results showed that the DHT22 sensor achieved high accuracy, with a temperature error of 0.02% and humidity errors ranging from 0.00% to 0.16%. The control logic functioned as expected, activating actuators only when the setpoint conditions were met, and the water distribution system operated efficiently using a 210-watt pump. Compared to prior studies that primarily focused on monitoring or single-aspect automation, this research offered a more comprehensive approach by integrating control logic, mechanical design, and electrical efficiency. The findings supported and expanded on previous work, particularly those utilizing similar sensors, but added value through direct implementation and real-world testing. This study contributed a practical and replicable solution for small- to medium-scale greenhouse automation, offering a low-cost and energy-efficient alternative for climate regulation in controlled agricultural environments
