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

Kegagalan daya atau kondisi power off yang tidak terencana pada mesin industri sering kali mengakibatkan kerugian finansial masif dan kerusakan peralatan yang serius. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem deteksi kegagalan daya secara real-time berbasis Internet of Things (IoT) dengan memanfaatkan ESP8266 sebagai Web Server mandiri. Metode penelitian yang digunakan adalah Research and Development (R&D), meliputi perancangan perangkat keras yang mengintegrasikan sensor tegangan, sensor arus ACS712, relay DC, dan motor stepper sebagai simulasi beban dinamis. Sistem ini menerapkan logika "Safe System" dengan ambang batas keamanan kritis sebesar 3,0V. Hasil pengujian membuktikan bahwa sistem mampu melakukan akuisisi data parameter listrik dengan tingkat akurasi mencapai 99% dan latensi rendah melalui protokol HTTP yang menjamin keandalan data 100%. Saat tegangan terdeteksi di bawah 3,0V, mikrokontroler secara instan memutus aliran relay dan menghentikan putaran motor untuk proteksi otomatis. Visualisasi data disajikan secara sinkron melalui LCD I2C dan dashboard web yang menampilkan nilai Voltase (V), Arus (mA), dan Daya (Watt) secara seketika. Kesimpulannya, sistem ini menyediakan solusi pemantauan mandiri yang efektif untuk meminimalkan waktu henti produksi (downtime) dan meningkatkan keandalan manajemen aset industri.

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.
