... Recently, HOMER ® software optimization tool, which is developed by National Renewable Energy Laboratory (NREL), USA [31] has been used in countless studies for optimization of different configurations of HRESs (e.g. PV/WT/Biomass/Battery/Converter [5],DG/PV/WT/Battery/ Converter [9], [32], WT/PV/Battery/Converter [4], [33], PV/Biomass gasifier/DG /Battery/Converter [16], PV/WT /DG/Battery/Converter [31] PV-battery [34], PV/DG/ battery/Converter [23], PV-WT [14], [35], [36], only PV [37], [38], PV/Hydro/DG/Battery/Converter [39], PV-WTbattery/FC [3], [40]- [42]) for electrification of rural [4], [16], [35], [40] and urban [5], [9], [32], [36] areas with countrybased study cases [4], [5], [38], [40], [9], [13], [14], [16], [32], [35]- [37] either for grid-connected [3], [13], [42]- [44], [16], [34]- [38], [40], [41], [45] or stand-alone [4], [5], [9], [13]- [16], [40] systems. HOMER fundamentally is a robust techno-economic optimization model [9]. ...
