Abstract
Control and operation of microgrid is about efficient control and monitoring. The control and
operation of microgrid involves the stability of voltage and frequency at generator bus bar. This
is achieved by maintaining the field excitation of synchronous generator to have 400V at the bus
bar. Likewise, frequency at the bus bar is maintained at 50Hz by controlling the speed of
generator. A DC shunt motor has been used, for this purpose, as a prime mover of synchronous
generator. Both the speed of DC motor and field of synchronous generator are varied from DC
drives. Both the drives are commanded by two Arduino separately. Emon Tx shield interfaced
with Arduino is used for metering purpose at the synchronous generator output. A small resistive
load box also attached at the output of generator.
