Abstract
Access to electricity and supplying reliable energy are the key elements that support local economic development and contribute to reducing poverty. Moreover, the problem of environmental protection can be considered as a factor of sustainable development. In response to these many challenges, appropriate national and regional policies, as well as mechanisms, have been implemented. In Mali, strong dependence on the importation of oil, growth in demand, and the low rate of electrification have pushed the highest authorities to think of diversified technological solutions like renewable energy for the satisfaction of energy demands, especially photovoltaics, for which the country has significant potential. The hybrid systems used is a compromise, because the emission rate of carbon dioxide emitted by thermal power plants must be reduced and limited to preserve supernatural disasters. For this, hybrid photovoltaic systems coupled to the grid increased, but the management of the production of these photovoltaics poses a lot of problem due to its intermittent status. It is in this context that we conducted an optimization study of a hybrid system photovoltaic connected to the grid. We applied our approach to the most extensive distribution post of Mali capital. For the simulation, we used the modeling and simulation tool named HOMER.
Highlights
Dependence on fossil fuels as a primary energy source will lead to the depletion of fuels, environmental pollution, and negative impacts on human health [1]
Global horizontal irradiance (GHI): Total amount of direct and diffuse radiation received on a horizontal surface expressed in Wh/m2
Diffuse horizontal irradiance (DHI): Total solar radiation received in one hour on a surface directly exposed to solar radiation, in Wh/m2
Summary
The intense energy demand, as well as the instant consumptions, believe very quickly according to the seasons (winter and summer), the depletion and impact of fossil fuel deposits are becoming threatening [1]. Dependence on fossil fuels as a primary energy source will lead to the depletion of fuels, environmental pollution, and negative impacts on human health [1]. The implementation of photovoltaic-grid hybrid power plants for the production of electricity will reduce the level of CO2 emissions, and contribute to increasing revenues [4]. To achieve these objectives and mitigate global warming, the use of renewable energies, which is an abundant resource accessible to all, is a sustainable solution. Many countries have begun to include solar energy programs in their planning to support sustainable development and environmental
