Appendix 1:RARF Rules Update

Resource Asset Registration Form – Business Rule updates

Site Information Tab– CMZ now a required field– If Generation load Split is 'Y', then Fixed Load Splitting % (for each ESIID's) must

total 100

Unit Information Tab– ALL: Unit Commercial date must be >= Site-In-Service Date– WIND: Latitude of Farm & Tower must be >=25 and <=37 decimal degrees– WIND: Longitude of Farm & Tower must be >=92 and <= 107 decimal degrees

Parameters Tab– ALL: HRL should be <= Real Power Rating (WARNING only)– ALL: LRL must be zero for Private Use Network Sites

Reactive Capability Tab– ALL: Lagging MVAR must be >= MVAR

Resource Asset Registration Form – Business Rule updates

Operational Parameters Tab– ALL: Minimum On Line Time (Warning! If decimal value is submitted then

Downstream System may round it UP)– ALL: Minimum Off Line Time (Warning! If decimal value is submitted then

Downstream System may round it UP)– ALL: Hot Start Time - (Warning! If decimal value is submitted then Downstream

System may round it DOWN)– ALL: Intermediate Start Time - (Warning! If decimal value is submitted then

Downstream System may round it DOWN)– ALL: Cold Start Time - (Warning! If decimal value is submitted then Downstream

System may round it DOWN)– ALL: Max Weekly Starts - Min value 1, Max value is 85 (WARNING)– ALL: Max Daily Starts - Min value 1, Max value 13 (WARNING)– ALL: Hot-to-Intermediate Time - (Warning! If decimal value is submitted then

Downstream System may round it DOWN)– ALL: Intermediate-to-Cold Time - (Warning! If decimal value is submitted then

Downstream System may round it DOWN)

Resource Asset Registration Form – Business Rule updates

CC Transitions Tabs– CC: Transitions From Offline required– CC: Transitions To Offline required– CC: Transitions must not skip configurations (eg: Offline to CC1_2)– CC: Should have a Transition for each Configuration (WARNING)

Line Data Tab– Zero impedance lines within same substation must be modeled on the

breaker/switch tab– Line Ratings for zero impedance lines must be valid (eg: 9999 not allowed)

Capacitor and Reactor Data Tab– Connected Device must also be defined either in the Breaker/Switch or in the

Transformer Tab– This field should be unique (No two capacitors should have the same controlling

breaker or switch)– Warning if Desired, Minimum, and Maximum voltage fields values have a range

not within 10% of the Voltage level of the Bus Bar being Regulated

Resource Asset Registration Form – Business Rule updates

Transformer Data Tab– Transformer High Side Manufactured Nominal Voltage must equal Voltage at

Highest Tap - Step Size voltage to reach Nominal Tap voltage– Error if the Transformer Resistance is less than 3 decimals, Warning if the

Transformer Resistance is greater than 2 but less than 5 decimals– Load Tap Changer must be 'Y' when AVR is ‘Y’– Error if Transformer Resistance to Reactance ratio >1, Warning if R/X >3

Load Data Tab– Connected Device must also be defined either in the Breaker/Switch or in the

Transformer Tab

GENMAP Packet Defined

Unit and Associated Resource Nodes: The GENMAP’s first page contains the mapping of generating units to Resource Nodes, or Settlement Points. Information such as the Unit’s and Resource Node’s substation, as well as the Resource Node’s voltage level and Connected Devices are listed. The Connected Devices are of all of the devices at a connectivity node where the Resource Node is located. Note that the Resource Node may not be located at the same connectivity node as the generating unit.

Unit-Associated EPS Meters: The Unit-Associated EPS Meters page shows the mapping of each generating unit to one or multiple EPS Meters. Information such as the Unit and EPS Meter’s substation, as well as the EPS Meter’s Meter ID, RID and Connected Devices are given. The Connected Devices consist of the devices at the connectivity node(s) where the EPS Meter is located. Note that a Unit-Associated EPS Meter may be located at a different substation than its mapped generating unit.

Unit-Associated EPS Flow-Calculation Modeling: The Unit-Associated EPS Meter Flow-Calculation Modeling page shows the mapping between a Unit-Associated EPS Meter and its associated conducting equipment used in the Flow-Calculation. Information such as the Unit and EPS Meter’s substation, Meter ID, RID and Connected Devices are given. The Flow-Calculation’s direction at the connected device is also given. See Explanation Verifying EPS Meter Flow-Calculation Modeling below.

•The one-lines are provided for two reasons – one to verify the accuracy of the meter and unit location on the one-line; the second as a tool to verify the mapping.•Each node and meter will have reference “Connections”. Each item listed in the connection column will refer to all equipment electrically connected to the node or meter point. These connections are represented as [CB]1234 or [XFMR]U1 and are shown on the one-line screenshots. •The connections column identifies the equipment type by offsetting the type in brackets, such as [CB]1234, where [CB] refers to the equipment type Circuit Breaker. The list below identifies the common equipment types:

o[XFMR] Transformer o[CB] Circuit breaker o[DSC] Disconnect (switch) o[UN] Generation Unit o[LN] Line o[LD] Loado[SERIES] Series Deviceo[SVC] Static-Var

Note: Transformer naming convention in GENMAP pkg is power transformer concatenation and may not match names provided in the RARF.

•The one-line screenshot uses several colors to define the operating voltage of the equipment and buses represented. The list below identifies the voltages associated with each color:

oPurple: 345kV oGreen: 138kV oBlue: 69kV oPink: Other voltages
