Case Study: Adrar Site %J Energy and Power %@ 2163-1603 %D 2012 %I %R 10.5923/j.ep.20120204.03 %X Abstract This work is aimed to study the wind and photovoltaic power systems connected to the conventional grid. The main interest of such a system is in its own production within the place of consumption, hybridization, and the pooling of resources and the contribution to the environmental protection. To ensure a better management system energy models have been developed for determining the power that subsystems can deliver under given weather conditions Simulation of different subsystems is performed using MATLAB-SIMULINK. The economic and environmental study is developed using the HOMER software. From an economic standpoint, this allows to compare the financial constraints on each system on the Adrar site (27.59N, 0.11W) located in the North-South of Algeria. It also permits to size and select the most optimal system based on two parameters, namely the cost and effectiveness. From an environmental perspective, this study allows us to highlighting the role of renewable energy in reducing emissions of greenhouse gas emissions. %K Wind %K Photovoltaic %K Grid %K Economy %K Environment %K MATLAB %K HOMER %U http://article.sapub.org/10.5923.j.ep.20120204.03.html
