Future Naval mission systems will place much larger demands on ship power infrastructure than is supported by present generation and distribution systems. This gap creates the need for a much more capable and agile platform, such as the development of advanced components, controls and design concepts. Energy storage solutions, such as an Energy Magazine (EM), will play a vital role in enabling new technologies. This work utilizes Power Hardware-in-the-Loop (PHIL) simulation to de-risk the system integration of a multi-port EM by exposing the EM to realistic shipboard conditions at its interfaces. Testing demonstrated a variety of scenarios such as the characterization of interface impedances for analysis of PHIL interfaces, as well as for model validation purposes; the dynamic support of stiff and/or nonlinear loads that are grid-fed, battery-fed, or shared between the two (EM buffered load pulsations); and distribution bus support during the loss of a generator or an overloaded set. This paper will further discuss the test setup along with selected results to illustrate practical lessons learned from performing a multiple port PHIL simulation at scale and the implications on digital twin development.
