IEEE 1547 Uses A technical standard—functional requirements for theinterconnection itself and interconnection testing A single (whole) document of mandatory, uniform,universal, requirements that apply at the point ofcommon coupling (PCC) or point of DER connection(PoC) Technology neutral—i.e., it does not specify particularequipment or type Should be sufficient for most installations A design handbook An application guide (see IEEE 1547.2) An interconnection agreement Prescriptive—i.e., it does not prescribe other importantfunctions and requirements such as cyber-physicalsecurity, planning, designing, operating, or maintainingthe area EPS with DERIEEE 1547 is:IEEE 1547 isnot:4
Importance of IEEE 1547 Energy Policy Act (2005) Cites and requires consideration of IEEE 1547 Standards andBest Practices for Interconnection; all states use or cite 1547. Energy Independence and Security Act (2007) IEEE cited as a standards developmentorganization partner to NIST as Lead to coordinate framework and roadmap for Smart GridInteroperability standards and protocols {IEEE 1547 & 2030 series being expanded}; Adoption by the majority of jurisdictional entities across N. America that set DERinterconnection rules55
6IEEE 1547 Scope and PurposeTitle: Standard for Interconnection and Interoperability of Distributed Energy Resources with AssociatedElectric Power Systems InterfacesScope: This standard establishes criteria and requirements for interconnection of distributed energyresources (DER) with electric power systems (EPS), and associated interfaces.Interconnection SystemDistributedEnergyResource(DER)Communications interfacePower interfacePurpose: This document provides a uniform standard forthe interconnection and interoperability of distributed energyresources (DER) with electric power systems (EPS). Itprovides requirements relevant to the interconnection andinteroperability performance, operation, and testing, and,safety, maintenance and security considerations.Image based on IEEE 1547-2018ElectricPowerSystem(Area EPS)Interconnection system: The collection of allinterconnection equipment and functions, taken asa group, used to interconnect DERs to an areaEPS. Note: In addition to the power interface,DERs should have a communications interface.Interface: A logical interconnection from one entityto another that supports one or more data flowsimplemented with one or more data links.6

Improve Transmission Asset Utilizationby Lifting Stability Limit Constraint,with Synthetic InertiaConstraint:Loss of system inertia reduces theamount of power that can beimported into a stability-limited loadpocket.Solution:Add synthetic inertia functionality toBESS’s located in the load pocket toincrease total system stability.Comments:Project scale is 50-250 MW, buteffective capacity is multiples ofnameplate capacity.Appropriate BESS capacity withsynthetic inertia functionality can alsocontribute to meeting NERCFrequency Responsive Reservescompliance requirement.9- Load Center250 MW Nameplate1000 MW Effective- 250 MW Nameplate1000 MW EffectiveSiC with short term OL, used w/ ES,has 4X benefit per MVA installed.Leverages new FRR requirements!COPYRIGHT MITSUBISHI ELECTRIC CORPORATION.
