Abstract:
Continuous supply of electricity,
when there are supply constrains is a major
challenge. Environmental concerns and non availability of fossil fuels increases the demand
for the use of renewable energy sources such as
solar. A domestic or an institutional customer
can support the country by the proper usage of
solar Resources. Further the usage of a battery
storage combined with the solar panel can
improve this. This paper analyses the domestic/
institutional usage of solar panels, (i) with and
(ii) without a battery storage, for both cases of
(i) with grid and (ii) standalone operation,
depends on the availability of solar irradiation
in a day. Here a typical domestic/institutional
solar power system taken into the study and
suitable sizes of solar panel, battery storage
were selected to achieve a reliable and smooth
operation of the system. The whole system is
modeled using PSCAD simulation. The design
of the controllers ensured the proper operations
of grid connected and standalone mode of the
system. Further MPPT control also used in such
a way to ensure the optimum usage of solar
power. The simulation results shows that this
arrangement improves the power availability
for domestic/institutional customers even
during the power failure periods.
