microgrid installations in California. The mandates for
compliance to IEEE 2030.7 for microgrid specifications are
expanding to commercially funded projects. Taken together,
these two standards enable flexibility and the customization
of the components and control algorithms to be specified,
certified, and deployed in microgrids, without sacrificing
and limiting advanced functionality and c- ompatibility.
Protection is being addressed in IEEE P2030.12, Draft
Guide for the Design of Microgrid Protection Systems.
IEEE P2030.12 is being developed by the IEEE SA's Guide
for the Design of Microgrid Protection Systems Working
Group. The document is intended to be an IEEE guide for
" the design of microgrid protection. " It is sponsored by the

describe transitions involving EPSs, and those shifts affect
conditions such as the fault response, coordination, and the
trip response when interconnected with an EPS as well as
fault detection, clearing, voltage control, and frequency.
All are critical functions that support the ability to protect
microgrids and interconnected EPSs.
The approved standards are being adopted and referenced by regulators, utilities, microgrid developers, and
stakeholders. State regulators and utilities refer to them for
interconnection rulemaking and requirements as well as
for considering any microgrid-related tariffs for reliability
and resiliency. Compliance with the standards is now being
required in requests for proposals and final contracts for
