and gives the feasible configuration with least total NPC as optimum configuration.
The decision variable (size of the PV array, number of batteries, tilt angle, and size of
converter) is used for the optimization process.

2.2 Selected cities for modelling

Bihar has 40 districts and has industrial hub city Darbhanga (26.11°N, 85.89°E) is
selected for this study (Fig. 11.4). As per the existing tariff, the per unit charge is Rs.
5.75 for 1–100 slab, Rs. 6.50 for 101–200 slab, Rs. 7.25 for 201–300 slab, and Rs. 8
above 300 slab.

2.3 Telecom load
The Base Transceiver Station (BTS) consists a primary load of telecom. The Tele-
com infrastructure of BTS provides wireless communication facility between opera-
tor network of telecoms and subscriber devices. Increasing global development of
BTS is a delightful place in those regions. After that often power distribution of grid
is break down for long time or no access to the power distribution grid. This type of
regions required diesel generator with batteries is provided back-up to grid for sup-
plying electricity and network availability. But in this type of requirement has high
level maintenance and high amount of diesel fuel to low level output. The COE is
high due to diesel price increasing and also rising greenhouse emissions. The focus
