This paper studies the technical, economic, and environmental analysis of wind and photovoltaic power systems connected to a conventional grid. The main interest in such systems is on-site consumption of the produced energy, system hybridization, pooling of resources, and contribution to the environment protection. To ensure a better management of system energy, models have been used for determining the power that the constituting subsystems can deliver under specific weather conditions. Simulation is performed using MATLAB-SIMULINK. While, the economic and environmental study is performed using HOMER software. From an economic point of view, this allows to compare the financial constraints on each part of the system for the case of Adrar site which is located to the northern part of the south of Algeria. It also permits to optimally size and select the system presenting the best features on the basis of two parameters, that is, cost and effectiveness. From an environmental point of view, this study allows highlighting the role of renewable energy in reducing gas emissions related to greenhouse effects. In addition, through a set of sensitivity analysis, it is found that the wind speed has more effects on the environmental and economic performances of grid-connected hybrid (photovoltaic-wind) power systems.
本文研究了与传统电网相连的风力和光伏发电系统的技术、经济及环境分析。此类系统的主要关注点在于所产生能源的就地消耗、系统混合、资源集中以及对环境保护的贡献。为确保对系统能源进行更好的管理，已使用模型来确定构成子系统在特定天气条件下能够输送的功率。使用MATLAB - SIMULINK进行仿真。同时，使用HOMER软件进行经济和环境研究。从经济角度来看，这使得能够比较位于阿尔及利亚南部北部的阿德拉尔地区该系统各部分的财务限制。它还允许基于成本和有效性这两个参数，对具有最佳特性的系统进行优化规模确定和选择。从环境角度来看，本研究有助于突出可再生能源在减少与温室效应相关的气体排放方面的作用。此外，通过一系列敏感性分析发现，风速对并网混合（光伏 - 风力）发电系统的环境和经济性能有更大影响。
