As a result, the break-even point is obtained as 4817 m. It defines that after this distance using a hybrid
system is more economic than the grid line system. However,
since the cost difference between the two system is low, 15.66%,
and the hybrid energy system is renewable and environment
friendly, this system still can be used for energy supplier of the
GSM base station.
The methodology described in this study provides an important
and systematic approach for design, analysis of hybrid energy systems
and choosing the best energy system for the remote areas.
The optimization ability is especially helpful if the simulation of
a system is very large and costly, precluding exploration of all
but a few input-parameter combinations. The development of the
metamodel makes possible, so better understanding of the true
relationship between input variables such as the PV size, wind turbine
rotor swept area, and battery capacity, and output variables
