Abstract

Maximum Power Point Tracking (MPPT) merupakan teknik untuk memaksimalkan daya dari photovoltaic. MPPT algoritma perturb and observe adalah metode yang banyak digunakan dan cukup sederhana. Metode (P&O) memiliki keterbatasan meningatkan efisiensi dan memiliki masalah osilasi, kecepatan pelacakan titik daya maksimum, konvergensi terutama saat mengalami perubahan kondisi atau radiasi cepat. Penelitian ini dilakukan untuk melihat kinerja algoritma perturb and observe dan melakukan modifikasi untuk meningkatkan kinerjanya mengatasi osilasi, konvergensi, efesiensi pelacakan serta kecepatan pelacakan. Kinerja dari algoritma akan di lihat melalui simulasi dan dievalusi untuk melihat seberapa besar peningkatan kinerja yang dapat di capai dari menggunakan algoritma P&O yang di modifikasi. Simulasi mununjukkan algoritma P&O modifikasi memiliki keungulan dari P&O konvensional. Maximum Power Point Tracking (MPPT) is a technique to optimize the power from photovoltaic. The perturb and observe algorithm MPPT is a widely used and fairly simple method. P&O method has limitations to increase efficiency and has oscillation problems, maximum power point tracking speed, convergence especially when experiencing rapid changes in condition or radiation. This reserch is conducted to see the performance of the perturb and observe algorithm and make modifications to improve its performance to overcome oscillations, convergence, tracking efficiency and tracking speed. The performance of the algorithm will be seen through simulation and evaluated to see how much performance improvement can be achieved from using the modified P&O algorithm. Simulation show that the modified P&O algorithm has advantages over conventional P&O.

Abstract

Pada awal abad ke-20, ilmu pengetahuan dan teknologi berkembang pesat, terutama dalam teknologi informasi dan otomatisasi produksi. Mesin industri mulai dikendalikan oleh sistem otomatisasi seperti PLC dan komputer. Salah satu implementasi teknologi otomatisasi ini adalah mesin listrik, khususnya mesin arus searah (DC). Salah satu mesin arus searah yang paling sering digunakan diindustri adalah motor arus searah (DC) karena kemampuannya menghasilkan torsi awal besar dan pengendalian putaran yang mudah. Namun, perubahan beban sering menyebabkan kecepatan motor tidak stabil, sehingga diperlukan pengaturan tegangan menggunakan konverter daya seperti DC chopper. DC chopper empat kuadran dipilih karena dapat mengatur kecepatan motor dalam dua arah dan melakukan pengereman. Lalu dpat dimonitoring melalui interface Simulink, yang memungkinkan pengoperasian tanpa saklar langsung dari laptop atau komputer. In the early 20th century, science and technology developed rapidly, especially in information technology and production automation. Industrial machinery began to be controlled by automation systems such as PLCs and computers. One of the implementations of this automation technology is electrical machinery, especially direct current (DC) machines, direct current (DC) motors have become popular in industry due to their ability to produce large starting torque and easy rotation control. However, load changes often cause unstable motor speed, so voltage regulation using a power converter such as a DC chopper is required. The four-quadrant DC chopper was chosen because it can adjust the motor speed in two directions and perform braking. It can then be monitored through a Simulink interface, which allows switchless operation directly from a laptop or computer.

Abstract

Motor listrik, khususnya motor DC, mempunyai peran penting dalam proses produksi industri untuk mencapai hasil optimal. Motor DC digunakan dalam berbagai aplikasi industri seperti conveyor, elevator, dan peralatan tekstil karena kemudahan pengaplikasian dan skala pengaturan kecepatan yang lebih lebar dibandingkan motor arus bolak-balik. Namun, penurunan kecepatan akibat beban sering menjadi masalah sehingga diperlukan sistem pengendalian, seperti kendali konverter empat kuadran (DC chopper), untuk mengatur arah putaran dan pengereman serta kecepatan motor DC. DC chopper mengubah tegangan DC menjadi tegangan DC variabel yang dapat dikendalikan, dan DC chopper empat kuadran memungkinkan kontrol tegangan motor DC pada empat daerah (positif atau negatif). Dalam penelitian ini, DC chopper digunakan untuk mengendalikan tegangan motor DC yang diintegrasikan dengan interface GUI Matlab untuk monitoring sistem. GUI Matlab dapat pengoperasian alat menggunakan komputer tanpa perlu mengaktifkan saklar manual, sehingga proyek ini dapat dijalankan dengan dua metode. Pada penelitian ini, pengujian sistem kendali konverter empat kuadran untuk motor DC dilakukan dengan interface GUI Matlab. Electric motors, especially DC motors, play an important role in industrial production processes to achieve optimal results. DC motors are used in various industrial applications such as conveyors, elevators, and textile equipment due to their ease of application and wider speed regulation scale compared to alternating current motors. However, speed degradation due to load is often a problem so a control system, such as a four-quadrant converter control (DC chopper), is needed to regulate the rotation and braking direction and speed of DC motors. A DC chopper converts a DC voltage into a controllable variable DC voltage, and a four-quadrant DC chopper allows control of the DC motor voltage in four regions (positive or negative). In this research, a DC chopper is used to control the DC motor voltage integrated with a Matlab GUI interface for system monitoring. The Matlab GUI allows operation of the device using a computer without the need to activate a manual switch, so this project can be run using two methods. In this research, testing of the four-quadrant converter control system for DC motors was conducted with the Matlab GUI interface.

Abstract

Penelitian ini bertujuan untuk mengevaluasi kinerja algoritma MPPT dengan metode P&O konvensional dan modifikasi pada sistem photovoltaic. Pengujian dilakukan dengan variasi iradiasi 200-600 W/m². Hasil menunjukkan metode P&O modifikasi mengurangi osilasi dan meningkatkan waktu pelacakan. Pada iradiasi 600 W/m², metode modifikasi mencapai MPP dalam 325 ms dengan daya 9.85 W, sedangkan konvensional memerlukan 345 ms dengan daya 8.775 W. Peningkatan iradiasi berbanding lurus dengan daya output dan berbanding terbalik dengan waktu pelacakan MPP. Penelitian ini membuktikan efektivitas metode P&O modifikasi dalam meningkatkan efisiensi dan stabilitas sistem MPPT pada aplikasi photovoltaic. This study evaluates the performance of Maximum Power Point Tracking (MPPT) algorithms using conventional and modified Perturb and Observe (P&O) methods in photovoltaic systems. Tests were conducted across irradiance levels of 200-600 W/m². Results demonstrate that the modified P&O method significantly reduces oscillations and improves convergence speed compared to the conventional approach. At 600 W/m² irradiance, the modified method achieves MPP in 325 ms with 9.85 W power output, while the conventional method requires 345 ms, producing 8.775 W. Increased irradiance correlates positively with power output and negatively with MPP tracking time. This research validates the effectiveness of the modified P&O method in enhancing efficiency and stability of MPPT systems in photovoltaic applications.
