Pulsed power loads (PPLs) are highly non-linear and can cause significant stability and power quality issues in a microgrid. One way to mitigate many of these issues is by designing an Energy Storage System (ESS) to offset the PPL. This paper provides a baseline for ESS control and specifications to mitigate the effects of PPL''s. ESS will
