Renewable energybased microgrids are presently attracting significant consideration. The smart grid system is presently considered a reliable solution for the expected deficiency in the power required from future power systems. The purpose of this study is to determine the optimal components sizes of a microgrid, investigating technical and economic performance with the environmental impacts. The micro grid load is divided into two small factories with electricity, both ongrid and offgrid modes are considered. The microgrid includes photovoltaic cells, backup diesel generator wind turbines, and battery bank. The estimated load pattern is 76 kW peak. The system is modeled and simulated by MATLABSimulink tool to identify the technical issues based on renewable power generation units. To evaluate system economy, two criteria are used the net present cost and the cost of generated electricity. The most feasible system components for the selected application are obtained, based on required parameters, using HOMER simulation package. The results showed that a WindPhotovoltaic (WPV) ongrid system is more economical than a WindPhotovoltaicDieselBattery (WPVDB) offgrid system as the cost of generated electricity (COE) is 0.266 kWh and 0.316 kWh, respectively. Considering the cost of carbon dioxide emissions, the offgrid will be competitive to the ongrid system as COE is found to be (0.256 kWh, 0.266 kWh), for on and off grid systems.
