摘要：Faced with the reality of limited fossil fuel reserves and the issue of greenhouse gases, agriculture, like other economic sectors, must develop efficient production systems in energy inputs. Within this context, this paper focuses on the problem is to optimize and size a power generation grid-connected system, resulting from the combination of renewable energy sources (RES), to supply power an agricultural farm of 37 hectares and a cold room for conservation of summer fruit, in the region of Sefrou-Morocco. In this article, economic study of hybrid electricity generation from the site was undertaken, with the aim of minimize the net present cost (NPC) which is the sum of the cost of the initial investment and the net present value of all costs of operation and maintenance over the estimate life of the project, which is 25 years. The environmental analysis was also carried out; emissions and renewable energy generation fraction (RF) are calculated as the main environmental indicator. Simulation results show that the hybrid energy system (HES) comprising one wind turbine of 100 kW, 15 kW of PV arrays and 40kW sized power converters connected to the grid, is the best option to meet the requirement of the load demand considered in this study, thereby producing 323,815kWh/yr, which 81% of electricity comes from RES and the remaining energy is provided by the grid, as well HES reduce about 51,000 Kg of emissions per year. In addition, a sensitivity analysis was performed considering four average values of wind speed
