Integrating digital pedagogy in teaching and learning activities towards education 4.0


ABSTRACT

The development of digital technology focus on teaching and learning activities has led to a change in learners' approach; therefore, teachers need to change the method which integrate digital tools based on the pedagogical perspective. This article presents a method of integrating digital pedagogy in teaching and learning activities towards education 4.0 for online teaching and learning in the form of distance learning and blended training methods. From this research results, the teacher sets up a teaching and learning plan that appropriately the teacher's training objectives and different training methods in either a face to face and/or digital environment.

Embedded photovoltaic monitoring device, system and method

An embedded PV monitoring device comprises a data receiving unit, a processing unit, a simulating unit and an evaluating unit. An embedded PV monitor system comprises a PV unit, a sensing unit and an embedded PV monitoring device. An embedded PV monitor method mainly utilizes the monitoring device to receive voltage and current parameters of the PV module and an environment working parameter. An output current and an output power of the PV module can be actually calculated, while the output current and the output power of the PV module can be simulated and estimated according to the voltage parameter and the environment working parameter. Thus, the field test monitoring and evaluating on the PV module can be automatically performed and a warning message can be timely outputted. This is advantageous to the detection of the yield of the PV module and the increase of the production quality.

A wireless visualization monitoring, evaluation system for commercial photovoltaic modules solely in MATLAB/Simulink environment

This paper proposes a wireless photovoltaic (PV) visualization monitoring, evaluation, and fault detection system based on the STM32F4DISCOVERY board with Bluetooth data transmission in the MATLAB/Simulink platform. All of the irradiance, the cell temperature, voltage, and current of PV devices are acquired through the microcontroller-based DAQ board. These measurements data are transferred to a host computer by both Bluetooth slave module and Bluetooth master one built in a laptop. These measurement data are visually displayed in the form of dashboard in the MATLAB/Simulink environment and are simultaneously input to PV model for theoretical simulation. The functions of evaluation and fault detection for PV modules under practical working conditions are conducted and displayed at the same software platform.
The proposed system has been proved with sufficient accuracy and confidence in the functions of visualization monitoring, evaluation, and fault detection. As compared with the well-developed ones, the proposed system has the advantages such as: reduce both cable and hardware configuration and integrate the all visualization monitoring, evaluation, and fault detection solely in the MATLAB/Simulink environment.

Self-sufficient energy recycling of light emitter diode/thermoelectric generator module for its active-cooling application

This paper presents the energy recycling and self-sufficient application of a novel high-power light emitting diode integrating with a thermoelectric generator module. The proposed lighting module in which a thermoelectric generator device is sandwiched between light emitting diode device and heat sink autonomously recycles the waste heat to self-sufficiently support for its active cooling with an electrical fan. The start-up responses of illuminance, temperature, current and power for the proposed module were evaluated through experimental measurement. The corresponding mathematical model was derived and simulation model was built using MATLAB/Simulink for verification. The illuminance, electrical, and thermal performances have a close agreement between experiment and simulation results. The technological viability about both autonomous operation and self-sufficient energy recycling for the novel module with the active cooling was validated. Compared with passive-cooling devices, the proposed module declines the working temperature and improves illuminance simultaneously.

Techno-Economic Analysis of Solar Power Plant Project in Binh Thuan, Vietnam

Abstract:
This paper aims to determine the important parameters of the solar power plant project located in Binh Thuan such as energy production, the number of solar panels, the number of the inverters and economic analysis. In this study, the solar power plant project with 1MW capacity installed and the location has the solar radiation from 1800 kWh/m 2 to 1900 kWh/m 2 per year is used to analyze. The PVSyst software was used to determine the energy production, the number of inverters, and the number of the solar panels. Furthermore, an economic model was proposed and used to identify the Net Present Value (NPV) with the discount rate 8% and 10%, Internal Rate of Return (IRR), Levelized Cost of Energy (LCOE) and payback years. From the results, the energy produced was around 1631MW per year, and NPV with discount rate 8% were beneficial, and LCOE was 21 cents USD per kWh. In addition, with the price to sell of electricity production to EVN was 9.35 cents, the Payback years was within in the range 9-12 years.
