“Blackouts”
are very common in Indian villages. It is the insufficient electricity supply.
Electrifying
villages is a rigorous task for the government primarily due to lack of
adequate infrastructure required.
Even in the presence of a Grid system, 24*7
provision of electricity cannot be guaranteed because of lack of resources to
do so!!
Solar Energy
run Microgrid systems have paved the path for the government to solve this
energy crisis.
A
microgrid is a Small-scale power grid system that can operate both
independently or in combination with the location’s main electric grid system.
There is
being done a lot on the government front for electrification of villages,
building transmissions, high tension lines and much more.
But power
scarcity has always been a major hiccup.
Here
renewable energy comes to rescue!!
Building up DC microgrid systems with the help
of solar energy can turn the tables. The major advantages of DC microgrids in the
villages are:
Ø Electricity for the household:
Solar power
rooftop DC microgrid system can provide electricity even to those communities
and homes where it was difficult to reach for the government.
These can be
set up without much need of infrastructure.
Ø Saving the loss of current on conversion:
The
conventional Solar energy systems work on by generating Alternate current (AC)
which is then converted into the Direct current (DC) and then used by home
appliances.
In this
whole process of conversion from one form to another 5-10% of energy get wasted.
While the DC
current produced in microgrid system is directly supplied to the households and
hence there is no wastage.
Ø Help in meeting the peak demand:
When the
supply is unable to meet the demands, the only way left out is “Power cut” to
regularize the peak energy demand.
But with the
solar Power DC microgrid system running in an area, there are rare chances of
facing power shortage.
Ø Surplus power generation by solar energy:
Rooftop
solar power DC microgrids help generate an additional source of electricity.
The somehow end the over dependency on the grid-tied electricity system.
It gives the
privilege to switch between the sources of electricity to choose from.
Ø Savings on costly conversion inverters:
The rooftop
solar energy systems installed earlier needed inverters, which would cost a lot
of transformation from AC to DC.
This made
the cost of installing the systems in villages expensive and hence less
feasible. But the invention of DC microgrid system had made the whole process
of setting up much cheaper.
Effects of power shortage
Power
shortage affects the lives in a much broader manner than expected. It takes a
toll on the economic, industrial and social growth.
Most of the
villages receive only up to 4-5 hours of daily energy supply. This hinders the
growth and progress of the community.
A quarter of
billion of Indian population still has no access to electricity.
Using
conventional sources of energy is not the ultimate measure for power shortage.
It drains down the economy and harms the environment badly.
Using solar DC microgrid systems or any other solar innovations is a complete win-win
situation on each front be it the economy, environment, sustainability and
availability.
Ø Cost Benefit:
The
government and the people would be in a comfortable position to invest in an
energy source that won’t cut holes in their pockets and has a promising future.
While the people living villages would now no
longer spend their lives in darkness.
Ø Balance in Demand and Supply:
The solar
power systems help bridge the gap between demand and supply well.
With solar
rooftop energy grid systems, there is no need to be dependent on the government
transmission.
And it
narrows down the need to invest in fossil fuel to generate electricity for
meeting demands.
An aggregated model of renewable wind and solar power generation forecast is proposed to support the quantification of the operational reserve.
