This paper presents the design and implementation of PWM boost converter using an 8-bit microcontroller that can be employed to achieve maximum power point tracking (MPPT) in photovoltaic systems (PV). In this paper, the used microcontroller is Arduino Uno that is based on microcontroller Atmega 328. Furthermore, the used PWM is governed using a Fast PWM Mode that is able to run at high frequency...
This paper presents a hybrid MPPT composed of two methods: incremental conductance (INC) and Fuzzy Logic (FL) control. This method is able to track maximum power point (MPP) under variable solar irradiance. In addition to that, it generates a modulation signal to adjust the duty cycle of boost converter to ensure fast MPPT process. In order to validate both of the effectiveness and the usefulness...
The excess photovoltaic produced energy goes to water electrolysis system during the daylight (surplus) hours to generate hydrogen to be stored in hydrogen tank for later use. The fuel cell generates electricity using the stored hydrogen as fuel to meet the load demand when the PV produced power is insufficient. A feasibility study and techno-economic evaluation of a stand-alone Photovoltaic/Fuel...
This paper presents Neural Network (NN) based A Two-Phase Interleaved Boost Converter (IBC) for Photovoltaic (PV) system. As known that this converter is the development of boost converter. In addition, it also functions to reduce output ripple current as well as to increase the output voltage of converter. This converter is driven by Pulse Width Modulation (PWM) which is governed by using controller...
This paper proposes a current-sensorless power-angle-based MPPT for single-stage grid-connected photovoltaic voltage-source inverters. The proposed tracker eliminates the use of the current sensor by using only the voltage sensor: The current sensor is substituted with a new quantity, which is the sine value of the power-angle (the phase angle between the inverter output voltage and the power grid...
This paper investigates PV panels' orientation strategies to achieve the maximum incident radiation over the surface of the solar cells at a reasonable cost. Conventionally, PV panels are tilted with the site's latitude angle or the difference between the latitude angle and the solar declination angle of the site. A monthly-based orientation strategy has been proposed and analyzed in this study. The...
Maximum power point tracking (MPPT) techniques are used in photovoltaic systems to maximize the PV array output power by tracking continuously the maximum power point (MPP) which depends on panel's temperature and irradiance conditions. The issue of MPPT techniques has been addressed in different literature. Among all these strategies, maximum power point tracker based on single variable are recently...
