SCHEDULE 3—INTERCONNECTION PROCESS,TECHNICAL REQUIREMENTS,AND OPERATING PROCEDURES A) Definitions The definitions defined in the "IEEE Standard for Interconnecting Distributed Resources with Electric Power Systems" (1547 Draft Ver. 11) apply to this document as well. The following definitions are in addition to the ones defined in IEEE 1547, or are repeated from the IEEE 1547 standard. i) "Area EPS"an electric power system(EPS)that serves Local EPS's. Note.Typically,an Area EPS has primary access to public rights-of-way,priority crossing of property boundaries,etc. ii) "Generation" any device producing electrical energy, i.e., rotating generators driven by wind, steam turbines, internal combustion engines, hydraulic turbines, solar, fuel cells, etc.; or any other electric producing device,including energy storagetechnologies. iii)"Generation System"the interconnected Distributed Generation(s),controls, relays,switches,breakers, transformers,inverters and associated wiring and cables, up to the Point of Common Coupling. iv)"Interconnection Customer" the party or parties who are responsible for meeting the requirements of this standard.This could be the Generation System applicant,installer,designer,owner or operator. v) "Local EPS" an electric power system (EPS) contained entirely within a single premises or group of premises. vi) "Point of Common Coupling" the point where the Local EPS is connected to an Area EPS. vii) "Transmission System", are those facilities as defined by using the guidelines established by the Minnesota State Public Utilities Commission; "In the Matter of Developing Statewide Jurisdictional Boundary Guidelines for Functionally Separating Interstate Transmission from Generation and Local Distribution Functions" Docket No.E-015/M-99-1002. viii) "Type-Certified" Generation paralleling equipment that is listed by an OSHA listed national testing laboratory as having met the applicable type testing requirement of UL 1741.At the time is document was prepared this was the only national standard available for certification of generation transfer switch equipment. This definition does not preclude other forms of type- certification if agreeable to the Area EPSoperator. B) Interconnection Requirements Goals This standard defines the minimum technical requirements for the implementation of the electrical interconnection between the Generation System and the Area EPS. It does not define the overall requirements for the Generation System. The requirements in this standard are intended to achieve the following: i) Ensure the safety of utility personnel and contractors working on the electrical power system. ii) Ensure the safety of utility customers and the general public. iii)Protect and minimize the possible damage to the electrical power system and other customer's property. iv) Ensure proper operation to minimize adverse operating conditions on the electrical power Interconnection Process for Distributed Generate Systems
