[IEEE 2019 7th International Renewable and Sustainable Energy Conference (IRSEC) - Agadir, Morocco (2019.11.27-2019.11.30)] 2019 7th International Renewable and Sustainable Energy Conference (IRSEC) - Design and Performance Analysis of a Photovoltaic Water Pumping System based on DC-DC Boost Converter and BLDC Motor
摘要： This paper presents the modeling, control and optimization of a photovoltaic water pumping system. The system consists of a DC-DC Boost converter, which is used as a link between a Solar Photovoltaic (SPV) panels and the three-phase inverter (VSI) to feed the BLDC motor. A centrifugal pump is connected to this motor in order to use the water pumped afterwards to multiple applications. Maximum Power Point Tracking (MPPT) control techniques are an essential part of improving the efficiency of photovoltaic (PV) systems. It is principally used to extract maximum possible power of the PV modules under any condition of solar irradiation. For this reason, P&O algorithm is used due to its high performance and its simplicity of implementation. The DC-DC Boost converter, compared to the various common DC-DC converters (Buck, Buck-Boost, SEPIC, Cuk...) has many benefits in SPV based applications, such as limiting the starting current of the motors. Using a BLDC motor is found to be the best option because of its high efficiency and reliability, better performance, and requires low maintenance. The considered system as well as the control strategies has been implemented in MATLAB-Simulink environment. The results show the effectiveness of the studied photovoltaic water pumping system.

[IEEE 2019 International Conference on Power, Energy and Innovations (ICPEI) - Pattaya, Chonburi, Thailand (2019.10.16-2019.10.18)] 2019 International Conference on Power, Energy and Innovations (ICPEI) - The concept of ‘ePVScooter’ an electric scooter integrated with portable photovoltaic charger system
摘要： This paper proposes the design, development and implementation of ‘ePVScooter’, an electric scooter integrated with portable photovoltaic charger system and support electrical outlet charger system. This is to ensure and maximize the driving utilization performance of existing electric scooter. Hence, the ‘ePVScooter’ charger functions can divide into 2 main input, which are the portable photovoltaic charger system (maximum charging rated at 24V 2A) and the electrical outlet charger system (maximum charging rated at 36V 2A). The proposed scooter also develops and installs the main driving system at front wheel with Brushless DC electric (BLDC) motor rated at 36V 500W. The ‘folding-up’ concept of the scooter is proposed. In order to ensure its performance and operational safety, the proposed design concept is validated together with a prototype ‘ePVScooter’ and various designs. Lastly, this paper also discusses the design, development and implementation of the proposed scooter and explores the new features for the existing electric scooter.
