New　electronic　power　distribution　systems　built　for　airplanes,　ships,　electric　vehicles,　data-centers,　nano-and　microgrids　dominantly　comprise　a　variety　of　power　electronics　converters　with　very　different　dynamic　characteristics.　Other　than　the　information　from　datasheets,　system　integrators　have　no　deeper　insight　into　dynamic　behavior　and　interactions　between　system　components　before　they　integrate　particular　systems.　This　paper　presents　a　generalized　black-box　modeling　method　of　three-phase　inverters,　rectifiers,　motors,　and　generators　for　system-level　study　and　on-line　stability　assessment.　Especially　interesting　for　OEM,　this　methodology　allows　equipment　manufacturers　to　provide　behavioral　models　of　their　components　without　disclosing　proprietary　information　such　as　topology,　structure,　control　loops　parameters,　etc.,　while　system　integrator　can　truly　benefit　from　using　these　models　for　their　(better)　system-level　design.　©　2020　IEEE.
