The comparison of dual axis photovoltaic tracking system using artificial intelligence techniques

Abstract

<span>In this paper, the efficiency of photovoltaic panels is improved by adding a sun tracking system. The solar tracking system is used for tracking the sun so that photovoltaic always faces the sun. This system uses a dual axis consisting of horizontal rotation axis and a vertical rotation axis. The horizontal rotational axis motion is to follow the azimuth angle of the sun from north to south. Then, to follow the sun's azimuth angle from east to west is the vertical axis motion. Both types of movements are controlled using a PID controller that is optimized with an artificial intelligence approach, namely particle swarm optimization (PID-PSO), firefly algorithm (PID-FA), imperialist competitive algorithm (PID-ICA), bat algorithm (PID-BA), and ant colony optimization (PID-ACO). Experiments of various approaches were carried out and the corresponding performance compared. The experimental results show that PID-BA performs best in terms of settling time and overshoot. The results also allow the comparison of different PID controller and the calculation of the fastest completion time.</span>

Maximum power point tracking of photovoltaic array using fuzzy logic control

“…A rule is applied to fuzzy input by the inference engine to determine the fuzzy output. Therefore, the real input value must be fuzzified, before the rule can be evaluated to obtain an appropriate linguistic value [15]− [28]. The rapid changes in the consumption of PV power can be determined by applying minimum perturbation in the output of photovoltaic voltage.…”

Komparasi PID, FLC, dan ANFIS sebagai Kontroller Dual Axis Tracking Photovoltaic berbasis Bat Algorithm

“…Kemampuan daya surya di Indonesia lumayan besar dengan keseriusan 4, 8 kWh atau m2 per hari dengan eksploitasi terkini sebesar 42,78 MW. Salah satu usaha buat tingkatkan kemampuan panel surya ialah dengan meningkatkan sistem kontrol tracking mentari [2]. Sistem kontrol tracking mentari merupakan sistem kontrol yang sering menjajaki posisi surya [3][4].…”

“…Penjejak matahari satu sumbu dibedakan jadi tiga, yaitu penjejak matahari sumbu horizontal, penjejak matahari sumbu vertikal, dan tilted-axis tracker. Sedangkan Penjejak matahari dua sumbu dibedakan menjadi dua, yaitu azimuth-elevation tracker dan tilt-roll (or polar) tracker [2]. Untuk mensimulasikan PV diperlukan transfer function sumbu harosontal dan sumbu vertical.…”

Hybrid Method for Optimization of Permanent Magnet Synchronous Machine (PMSM) Rotation using FA-ANFIS

“…In this method, the tuning is done in a closed loop where the reference input used is a step function. The controllers in this method include proportional (Kp), integral (Ki), and derivative (Kd) controllers [9].…”
