The increasing penetration of renewable energy generation
(REG)
in t
he
m
icrogrid paradigm
has brought with it larger uncertainty in the scheduled generation. This along with the inevitable variation
between actual load and for
ecasted load has further accentuated
the issue of real
-
time
power
balancing.
With
the advent of sm
art loads and meters supported by advanced communication technologies
,
several
new possibilities for demand side management
have opened up
.
In
this
paper
,
a real time optimization
strategy
for
load side energy management system
(EMS)
and for power
balance
is proposed.
The
proposed strategy achieves power
balance by optimizing load reduction
.
The objective is to ascertain
uninterrupted power to critical loads and reduce non
-
critical loads depending on the priorities for various
loads.
To further enhance the
flexibility of the system, the addition of a battery to the management model
is
also
discussed.
The proposed algorithm
also makes the system
tolerant
to possible generator failures
if
battery is added to the system. The effectiveness of the proposed online
power balancing strategy via
optimization is demonstrated through various
simulation
case studies
