The present work analyses the feasibility of a wind-diesel generator-battery hybrid system. The wind energy resource data are collected from the weather station at the Renewable Energy Development Center of Bouzareah in Algeria. The recorded values vary from 5.5？m/s to 7？m/s at 25？m. The hybrid system analysis has shown that for a household consuming 1,270？kWh/yr, the cost of energy is 1.205？USD/kWh and produces 2,493？kWh/yr in which 93% of electricity comes from wind energy. From this study, it is clear that the optimized hybrid system is more cost effective compared to the diesel generator system alone where the NPC and COE are equal, respectively, to 19,561？USD and 1.205？USD/kWh and 47,932？USD and 2.952？USD/kWh. The sensitivity analysis predicts that the grid extension distance varies from 1.25 to 1.85？km depending on wind speed and fuel price which indicate a positive result to implement a stand-alone hybrid power system as an alternative to grid extension. In addition to the feasibility of this system, it can reduce the emission of the CO2, SO2, and NOx, respectively, from 4758 to 147, from 9.45 to 0.294, and from 105 to 3.23？kg/yr. Investments in autonomous renewable energy systems should be considered particularly in remote areas. They can be financed in the framework of the National Energy Action Plan of Algeria. 1. Introduction An important challenge for Algeria to take up is the implementation of health care services in isolated coastal and mountainous regions of the north, high plains, and desert regions of the south. Communities living there lack electricity for water sterilization, domestic use, medical services, education, and irrigation. These remote areas are not supplied with power lines. The important infant and maternal mortality rate in these regions is due essentially to transmissible diseases, scorpion poisoning, and malnutrition. The sub-Saharan localities are also threatened by the extension of sexually transmissible diseases as discussed by Armini [1]. The constructions of health clinics electrified by local resources such as solar and wind energy become the most suitable alternative. In this context the aim of the present study is to control the feasibility, analyze, and simulate a wind-diesel generator-battery hybrid system. Many research works including feasibility, optimization, and simulation studies have been carried out on hybrid energy systems [2–4]. Khelif et al. [2] have undertaken a feasibility of a hybrid PV/Battery/Diesel power plant using real meteorological data equipment costs to show the possibility of modifying
