University of Scholars has started its journey in 2015 with five departments at the outset. The Trustee Board of the university aims to establish a research-intensive modern private university for Bangladeshi as well as international students which will produce world-class researchers and industry leading professionals. The university is working with the slogan- We Build Professionals, and following American curriculum with strong emphasis on the use of technology for teaching and learning process. Therefore, we are adopting the newest educational technologies (EdTech) to modernize our Learning Management System (LMS) for the best experience of learning as well as teaching. This is the first initiative of such kind in Bangladesh. Our congenial atmosphere and flexible policy inspire the faculty members who are highly qualified having academic degrees and professional training from home and abroad.
A Case Study on the Cost-effectiveness of Net Energy Metering of Residential Grid-Connected Photovoltaic in the Context of Bangladesh (1st Author) DOI 10.1109/ICEEICT53905.2021.9667846 Abstract: Increasing electricity generation without harming the environment is the foremost concern in recent times. The use of solar energy in the perspective of Bangladesh is very much appreciated due to environmental reasons. If a solar plant is implemented, problems arise such as the costing of the panel with battery and wastage of energy during daytime due to excess generation compared to battery capacity. Net Energy Metering (NEM) with grid-connected PV can resolve these problems. The research in this paper focuses on using PVsyst to design a grid-connected home solar system that takes into account meteorological, technical, and loss aspects. The net energy exchange, as well as the cost-effectiveness of the implemented scheme, is determined by the Sustainable and Renewable Energy Development Authority (SREDA) net metering calculator after implementation. In the proposed case, it was found that the total investment of 22,545.63 USD will give a profit of 26,881.78 USD to the investor with a payback period of 6.85 years. The paper concludes that residential grid-connected solar is a nouveau concept within the setting of Bangladesh, which will help to tackle the excess demand for electricity with a good economic outcome.
Design of a Bidirectional DC Microgrid Controlled with Energy Management System (1st Author) Abstract: Energy management integrating renewables and conventional grids might be viable for meeting current and future energy demands. The amount of energy generated from renewable sources varies from time to time. When a hybrid renewable-based unidirectional dc microgrid is linked to the utility grid, energy might be underutilized during periods of surplus generation. Bidirectional dc microgrid systems can help with energy management and address various environmental challenges. The architecture of a bidirectional dc microgrid, including solar photovoltaics (PV), wind turbines, battery storage and conventional utility grid has been designed in this work. An energy management system (EMS) is designed to supply the required energy to particular loads under various conditions. Maximum available power is extracted from PV using Maximum Power Point Tracking (MPPT), using the P&O algorithm. When the combined power of the PV panels and wind turbine exceeds the demand of the loads, the extra energy is used to charge the batteries. The remaining energy is supplied to the power grid through an inverter when the battery's state of charge (SOC) reaches 90%. When there is a dearth of generated electricity from renewable sources, and the battery's SOC is less than 30%, power is drawn from the utility grid and provided to loads. The system design is implemented in MATLAB/Simulink and the effects of altering the circumstances on the electrical parameters are observed. Variable load and generation circumstances are used to generate the simulation results. Details - (link)
Analyzing the Technical Constraints of Single Phase Residential Grid-Connected PV under Net Energy Metering Scheme (1 st Author) Abstract: Integrating clean and sustainable energy sources into the conventional utility grid benefits both the environmental concerns and the economy. The net energy metering (NEM) scheme is convenient in this situation. After meeting the energy requirements of its associated loads, it integrates excess photovoltaic (PV) generation into the main grid, lowering the cost of massive battery storage and increasing the supply of clean energy to the grid. From the perspective of single-phase residential grid-connected PV systems, this can have beneficial repercussions in addition to the aforementioned cause. Integration of a single-phase distributive generation system, such as solar PV with the utility grid, introduces various concerns with power quality issues, including overvoltage, an increase in fault level and harmonics effect. This paper evaluates the effects of technical parameters on residential single-phase grid-connected photovoltaic integration with the IEEE 14 bus system. Matlab/Simulink is used to develop the system, which includes an IEEE 14 bus and a single-phase grid-connected PV module connected to the following bus with its associated residential loads. The effects of varied PV module sizing and load variation on the technical parameters are observed. The research findings are compared to the current models of residential three- phase grid-connected PV under the NEM scheme. The proposed sizing and mitigation of the systems impact by technical concerns are discussed. Details - (link)
