Abstract

Photovoltaic (PV) is a component for converting solar energy into electrical energy. On the other hand, the characteristics of PV performance are fluctuating, additional circuits are needed to maximize PV performance. This research discusses the maximum power point tracker (MPPT) in a solar charge controller system using PIC microcontroller as a solution to maximize PV performance. The MPPT algorithm used is perturb and observe (PO) with PV power parameters because this algorithm is often used and has good efficiency. This research system was tested using a voltage scale of 15 V, 16V, 17 V, 18.1 V, 19 V, 20 V, 21 V, 22 V, 23.1 V, 24.1 V, and 25 V with the lowest average error value of 3.01447379% and highest 4.312288%. Testing the working characteristics of the 120WP solar panel shows that the solar panel will work optimally when the conditions are sunny and the temperature is not high. The results of testing solar panels with the highest average output voltage of 22.1 V. From testing the system on solar panels shows the value of the ADC output voltage with an average of 12.603V in sunny conditions, 12.372V in sunny cloudy conditions, 12.23V in cloudy conditions, 12.5 V in an obstructed condition. In testing system efficiency using the PO algorithm with an average result of 80.4818%.

Abstract

Hydraulically, the flow behavior in straight and turning lines is different because it is influenced by geometric factors and other related hydraulic parameters. The hydraulic behavior of straight and turning lines has been widely studied by means of theoretical, experimental and numerical approaches. The theoretical approach is very limited and still leaves many questions, while the experimental approach requires large research costs, so that the numerical approach through computation can be used as a reliable alternative research as long as it is based on a theoretical basis and valid experimental data. The purpose of this research is to analyze and predict the flow behavior of channel bends using Particle Swarm Optimization (PSO).  optimization algorithm. The results obtained indicate that the PSO can be relied upon in modeling the fluid flow velocity at the channel bends with an average error percentage of 8% compared to the measured data.
