The Viet Nam policy tariff, either selling the total electricity generated or consuming of Photovoltaic project

The development policy of the photovoltaic power plant of government strongly impacts to NPV and LCOE. According to the policy tariff, either selling the total electricity generated or consuming (FiT). The values in different countries with a FiT rate is shown in Table 2, as well as the years supported. From Table 1, the country has the best FiT rate in Japan (0.297 USD/kWh) and the worst FIT rate in the UK (0.052 USD/kWh). However, the simulation...

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...

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,...

Active model for online activities

Students have a habit of completing assignments online instead of watching lectures and/or reading document. One of the solutions is to encourage students to complete lessons is to embed quiz scattered in videos or documents. In addition, from practical study at Lac Hong University proposed an active online model for teaching online as shown in Figure 1. Accordingly ...
