Abstract
This thesis presents the solar roof-top photo-voltaic generation capacity at Bishnumati
feeder of Balaju Distribution Control System (DCS) with its performance and voltage
profile analysis during grid connection by considering eleven potential commercial and
non-commercial buildings. The Building Foot-Print Area (BFA) obtained is 8915.13
m2 and the actual photo-voltaic area (PVA) is 4190.11 m2, which is used to install the
solar module in the roof of the selected buildings. PVsyst is used for performance
analysis, the energy generated by solar array (E_array) and energy supplied to the grid
(E_grid) is 1018.319 MWh and 982.039 MWh per year respectively. The performance
ratio over the year is 0.74. The average capacity factor of overall installation is obtained
as 17 %. ETAP is used for feeder modeling and load flow analysis. Form load flow
analysis the minimum grid voltage before solar PV injection is 10.32 kV at a nominal
bus voltage of 11 kV. After injection of solar PV into the grid, the minimum bus voltage
is improved to 10.53 kV.
