Solar Radiation Estimation from the Measurement of Sunshine Hours over Southern Coastal Region, Bangladesh

Abstract: In this study,the global solar radiation over the southern coastal region of Bangladesh is estimated from the duration of relative sunshine hours. Five models are considered to estimate the solar irradiance. These models are modified form of classical Angstrom – Prescott regression equation. A quadratic logarithmic model, relating the relative solar radiation and the relative sunshine hours is proposed for southern coastal region of Bangladesh. NASA Surface Meteorology and Solar Energy (SSE)have record of solar radiation data all over the world, measured from satellite. As Bangladesh Meteorological Department or any other organization has no record of measured solar radiation data for the considered locations, the estimated solar irradiance from the proposed regression model is compared with the data recorded by NASA SSE. Also t – statistics is applied to the estimated results to determine whether or not they are statistically significant at a particular confidence level.

Hybrid Energy System for Upgrading the Rural Environment

Abstract: Off-grid hybrid energy systems are attractive options for supplying electricity to rural areas in all aspects like, reliability, sustainability and environmental protection. It is especially best option for communities living far in the interior areas, where grid extension is not appropriate. Ethiopia is also facing the same problem. Many villages are very far from the grid. Therefore, off grid hybrid systems will supply those villages. This work presents the photovoltaic, wind turbine, battery bank and diesel generator based off grid system, which is sized and simulated for the rural community of Addis Border village in the Southern Regional State of Ethiopia. Primary load demand of 142kWh/day, peak load of 26kW, deferrable energy requirement of about 27kWh/day, and deferrable peak load of 3.6kW are involved during modeling of the proposed stand alone power system.

Renewable Energy Sector in Bangladesh: The Current Scenario, Challenges and the Role of IoT in Building a Smart Distribution Grid

Abstract: Advancement in electricity is the key ingredient that can actively take part in alleviating poverty and drastically improve the socio-economic status of the people of Bangladesh. The incorporation of renewable energy sources would help the country meet the energy requirement as well as contribute positively towards building a sustainable planet. The paper has extensively discussed the potential aspects of renewable energy resources in Bangladesh and how the Internet of Things can facilitate the implementation of intermittent sources. The regulatory and socio-economic aspects of the renewable energy industry have been explored and sustainable solutions will be discussed to fast-track the process of integrating various renewable energy sources in the power grid to meet the energy demand. The paper discusses the challenges associated with the RE integration in Bangladesh’s power mix and tries to mitigate it through the IoT. Besides that, an RE map for Bangladesh along with prospective power network has also been discussed in this work.

Feasibility and Cost Analysis of Grid Connected Hybrid Solar Home System: A Case Study of Chattogram District in Bangladesh

Abstract: There has been a talk of solar home and its installation for a long time, but, feasibility and cost analysis are highly important point for a low-income country like Bangladesh. This paper focuses on a solar based home energy solution to reduce the consumption from grid in the residential sector in Chattogram district, Bangladesh. The proposed system will focus on a grid-connected solar system which will contribute to the consumption of a home as well as the grid. Large solar-based plants are not particularly a practical solution due to small and limited landmass. Hence, the ultimate plan is to focus on designing a system which will be efficient considering the specific facts of Chattogram, Bangladesh. The Global Horizontal Irradiation (GHI) and Diffuse Horizontal Irradiation (DHI) for Chattogram have been taken into consideration to come up with the daily energy potential. A detailed calculation of the energy consumption has also been shown in the paper as well. HOMER software has been used to validate the system. Finally, the annual cost and consumption analysis have been done to fill up the research gap in existing literature.

High Spatial Resolution Simulation of Sunshine Duration over the Complex Terrain of Ghana.

Abstract: In this paper, we propose a remote sensing model based on a 1 × 1 km spatial resolution to estimate the spatio-temporal distribution of sunshine percentage (SSP) and sunshine duration (SD), taking into account terrain features and atmospheric factors. To account for the influence of topography and atmospheric conditions in the model, a digital elevation model (DEM) and cloud products from the moderate-resolution imaging spectroradiometer (MODIS) for 2010 were incorporated into the model and subsequently validated against in situ observation data. The annual and monthly average daily total SSP and SD have been estimated based on the proposed model. The error analysis results indicate that the proposed modelled SD is in good agreement with ground-based observations. The model performance is evaluated against two classical interpolation techniques (kriging and inverse distance weighting (IDW)) based on the mean absolute error (MAE), the mean relative error (MRE) and the root-mean-square error (RMSE). The results reveal that the SD obtained from the proposed model performs better than those obtained from the two classical interpolators. This results indicate that the proposed model can reliably reflect the contribution of terrain and cloud cover in SD estimation in Ghana, and the model performance is expected to perform well in similar environmental conditions.
