Abstract

This research focuses on optimizing the control system to improve voltage stability in a 10 kW Solar Power Plant (PLTS) located in a tropical region. The main issue addressed is voltage fluctuation caused by the intermittent nature of solar radiation (200–1200 W/m²) and temperature variations (20–50°C), which result in up to 12% overshoot in the inverter. The proposed method implements a Proportional-Integral-Derivative (PID) controller optimized using the Particle Swarm Optimization (PSO) algorithm with real-time irradiation input data. The research integrates a 100 Hz digital low-pass filter to mitigate sensor noise under low irradiation conditions. Simulation results show that the PID-PSO system successfully reduces overshoot from 12.1% to 4.2% under high irradiation, and decreases settling time from 0.62 seconds to 0.31 seconds. The digital filter effectively reduces measurement deviation from 7.2% to 2.8% at 200 W/m² irradiation. The PSO optimization achieved optimal convergence within 37 iterations with an Integral of Time-weighted Absolute Error (ITAE) value of 0.18. This study concludes that the implementation of PID-PSO with a digital filter significantly enhances the voltage stability of the PLTS by 20.3% compared to conventional PID control and is ready to be applied in tropical-region smart grid systems.

Abstract

This study implements Passivity-Based Control (PBC) on the Teensy 4.1 embedded platform for Flywheel Energy Storage System (FESS) equipped with wireless power flow monitoring. The objective of the study is to overcome the limitations of conventional controllers in handling nonlinear dynamics of FESS and integrate remote monitoring capabilities to support smart grid infrastructure. The research method uses an experimental approach by designing an Interconnection and Damping Assignment PBC (IDA-PBC) controller optimized for embedded computing limitations, implemented on Teensy 4.1 with a 10 kHz control loop. The system is integrated with an ESP32 wireless module for real-time data transmission to a remote dashboard. The results show that IDA-PBC is superior to Field-Oriented Control with an increase in rise time of 24.5%, settling time of 34.0%, overshoot of 74.4%, and disturbance rejection of 46.2%. Energy efficiency increases by 3.8% absolute (89.9% vs 86.1%) with lower total harmonic distortion. The implementation on Teensy 4.1 proved viable with 45.2% CPU utilization, while wireless monitoring achieved 18.5 ms latency and 0.12% packet loss. The contributions of this research include empirical validation of IDA-PBC on a real-world implementation, benchmarking of embedded platforms for nonlinear control, and demonstration of cyber-physical integration on FESS that supports the development of a more efficient and reliable smart grid.

Abstract

The rapid advancement of portable electronic device technology, particularly laptops, necessitates a charging solution that is faster, more efficient, and compatible with diverse standards. The USB-C Power Delivery (USB-C PD) protocol has emerged as a universal charging standard due to its ability to support flexible voltage and current configurations. Nevertheless, the overall charging efficiency remains constrained by dynamic load behaviour, fluctuations in power sources, and the limitations of conventional power management techniques. This paper described the integration of a Maximum Power Point Tracking (MPPT) algorithm into a USB-C PD-based fast-charging system for laptops, aiming to enhance energy transfer efficiency between the power source and the device. The research methodology involves the design and simulation of a power management system incorporating MPPT, hardware prototyping, and performance evaluation based on efficiency, charging duration, and voltage stability metrics. Experimental results indicate that the implementation of the MPPT algorithm significantly improves charging efficiency, minimizes energy losses, and reduces charging time compared to conventional charging methods. The proposed approach not only contributes to the advancement of USB-C PD-based fast-charge technologies but also lays a foundation for future developments in intelligent, energy-efficient power management systems. These findings have broad potential applications in next-generation electronic devices that demand fast, adaptive, and sustainable charging solutions.

Abstract

Horticultural products require storage at temperatures ranging from 0–10 °C to maintain post-harvest product quality. Cold storage is an effective solution because it can maintain temperature stability, which affects the rate of respiration, microbial activity, and the shelf life of products. However, conventional cold storage systems that use only a single compressor are less flexible in adjusting to thermal loads, which reduces efficiency, accelerates component wear, and decreases the overall reliability of the system. This study designs and simulates an automatic temperature control system based on a Programmable Logic Controller (PLC) by regulating two compressor units according to room temperature and integrating the principles of hysteresis, staging, and rotation. The system uses an upper temperature limit of 10 °C, a lower temperature limit of 0 °C, and a hysteresis point at 5 °C as a reference for changing operating modes. Compressors can operate simultaneously to speed up cooling, compressors can operate alternately to balance the load while maintaining optimal temperature, and compressors can stop simultaneously to stop cooling and prevent product freezing. The simulation was carried out using CX-Programmer for ladder logic and CX-Designer for Human Machine Interface (HMI) visualization. Testing involves temperature variations above 10 °C, in the range of 0–10 °C, and below 0 °C to verify the system's response. The results show that the system is able to maintain the storage room temperature at optimal conditions automatically and stably. The system successfully applied the principles of hysteresis, staging, and rotation effectively in response to temperature changes. The system is also equipped with automatic recovery capabilities that maintain precise control after a power outage. This design has the potential to be applied in food preservation, supply chain logistics, and temperature-sensitive industries, as well as supporting the development of cooling and autonomous systems.

Abstract

Penelitian ini menganalisis efektivitas penerapan kapasitor bank dalam meningkatkan faktor daya pada gedung komersial berbeban reaktif tinggi menggunakan simulasi ETAP 19.0. Empat skenario dievaluasi: beban maksimum dan minimum dengan serta tanpa kapasitor bank. Pada beban maksimum (895 kVA), pemasangan kapasitor bank (400 kVar) meningkatkan faktor daya dari 78,3% menjadi 96,4%, mengurangi daya reaktif sebesar 66,4% dan menstabilkan tegangan di 384 V. Namun, pada beban minimum (173 kVA), kapasitor bank berkapasitas tetap (200 kVar) menyebabkan overcompensation, menghasilkan daya reaktif negatif (-150 kVar), faktor daya leading (-87,4%), dan kenaikan tegangan hingga 400,3 V yang berisiko merusak peralatan. Analisis menunjukkan kapasitas optimal kapasitor bank untuk beban maksimum adalah 389 kVar, sedangkan untuk beban minimum tidak diperlukan atau maksimal 50 kVar. Temuan ini mengonfirmasi ketidakefektifan kapasitor bank berkapasitas tetap pada beban dinamis. Penelitian merekomendasikan penggunaan sistem kapasitor bank otomatis dengan step control untuk menyesuaikan kapasitas secara real-time, memastikan faktor daya memenuhi standar PLN (≥0,85) sekaligus menghindari overcompensation. Pendekatan ini tidak hanya menghindari denda akibat faktor daya rendah, tetapi juga meningkatkan keandalan sistem.

Abstract

Solar-powered Public Street Lighting (PSL) is an environmentally friendly lighting solution that is widely implemented in remote areas as well as strategic locations. However, the reliability of solar-powered street lighting systems often faces challenges due to dependency on weather conditions and limited battery capacity, which can cause the lights to turn off before the end of the operational period. This study aims to design and evaluate an Automatic Transfer Switch (ATS) system as an automatic power source switching mechanism to improve the reliability of solar-powered street lighting. The proposed system utilizes a Solar Power Generation System (SPGS) as the primary power source and the utility grid (PLN) as a backup source. Testing was conducted using street lighting loads of 10 Watt and 20 Watt lamps, with observed parameters including battery voltage, charging current, load voltage and current, and ATS switching time. The test results show that the solar power system is capable of supplying street lighting for an average duration of approximately ±10 hours and 50 minutes per night. The ATS switches to the utility grid when the battery voltage drops to 11.6 VDC and switches back to the solar power system once the primary source becomes stable again. The switching process is characterized by a brief voltage drop, which is a normal characteristic of ATS operation designed to ensure system safety and prevent electrical disturbances. Based on the experimental results, it can be concluded that the implementation of an Automatic Transfer Switch (ATS) in solar-powered street lighting systems effectively enhances lighting continuity, system reliability, and component protection, making it suitable for application in airport environments and other areas requiring high lighting reliability.

Abstract

This study investigates the performance and energy efficiency of a three-phase induction motor controlled by a Variable Speed Drive (VSD) in a fatty acid pump system at the Permata Group processing plant. The research is motivated by the increasing need for energy savings and operational reliability in continuous industrial processes where pump load profiles are highly dynamic. The objective of this study is to evaluate the effectiveness of VSD implementation in reducing energy consumption and improving motor operating characteristics under real plant conditions. Data were collected during actual production cycles through direct measurement of electrical and mechanical parameters, including current, voltage, frequency, torque, flow rate, and power consumption. The analysis compares the performance of the pump system before and after the application of VSD, using descriptive statistical analysis and graphical evaluation of motor behavior under various load conditions. The results demonstrate that the application of VSD significantly reduces energy consumption at partial loads while maintaining stable pump output and minimizing mechanical stress. The motor also shows improved operating efficiency and lower thermal loading compared to constant-speed operation. These findings indicate that VSD-based control offers a practical and cost-effective solution for industrial pump systems, especially in fatty acid processing operations where flow demand fluctuates during production. The practical implications are substantial, highlighting opportunities for energy conservation, equipment longevity, and process optimization without compromising product quality or throughput, making the system suitable for broader adoption in similar industrial environments.
