Figure 11.1 Solar–wind–battery hybrid of telecommunication.

The intent behind this study is to economic feasibility of different HSs such as
PV–wind–diesel–battery, wind–diesel–battery, PV–diesel–battery, PV–wind–diesel,
and wind–diesel and PV–diesel for a remote telecom station.

2 Methodology

2.1 Hybrid optimization model for electric renewable pro

Hybrid optimization model for electric renewable (HOMER) Pro is a renewable-
energy-based system optimization tool developed by National Renewable Energy
Laboratory (NREL), USA is used to model HS. It is freely downloadable soft-
ware [38]. HOMER perform optimization, simulation and sensitivity analysis [39]
(Fig. 11.2). This is a general-purpose system design tool that enables power system
design either for off-grid or grid-connected application. HOMER sizes up the sys-
tem specifications such as the load profile, wind resources, solar resources, die-
sel price, system control parameter, constraint parameter as well as components
technical and economics details. HOMER performs numbers of hourly simulation
for best possible matching between the load and the supply in order to design an
optimal system. Thereafter, it creates feasible system configurations categorized
according to cost effectiveness and presents the optimal configuration based on the
lowest NPC. HOMER also performs the sensitivity analysis to explore the effect of
