P5MIN_INTERCONNECTORSOLN

The five-minute predispatch (P5Min) is a MMS system providing projected dispatch for 12 Dispatch cycles (one hour). The 5-minute Predispatch cycle runs every 5-minutes to produce a dispatch and pricing schedule to a 5-minute resolution covering the next hour, a total of twelve periods. P5MIN_INTERCONNECTORSOLN sets out the results of the capacity evaluation for Interconnectors, including the calculated limits for the interval.

Column Official MMS Datatype GR-MMS Datatype Comment
RUN_DATETIME datetime(3) 🔑 datetime2(0) 🔑 Unique Timestamp Identifier for this study
INTERCONNECTORID varchar(10) 🔑 varchar(10) 🔑 Interconnector identifier
INTERVAL_DATETIME datetime(3) 🔑 datetime2(0) 🔑 The unique identifier for the interval within this study
INTERVENTION numeric(2, 0) tinyint 🔑 Flag to indicate if this result set was sourced from the pricing run (INTERVENTION=0) or the physical run (INTERVENTION=1). In the event there is not intervention in the market, both pricing and physical runs correspond to INTERVENTION=0)
METEREDMWFLOW numeric(15, 5) numeric(15, 5) SCADA MW Flow measured at Run start. For periods subsequent to the first period of a P5MIN run, this value represents the cleared target for the previous period of that P5MIN run.
MWFLOW numeric(15, 5) numeric(15, 5) Cleared Interconnector loading level (MW)
MWLOSSES numeric(15, 5) numeric(15, 5) Interconnector Losses at cleared flow
MARGINALVALUE numeric(15, 5) numeric(15, 5) Marginal cost of Interconnector standing data limits (if binding)
VIOLATIONDEGREE numeric(15, 5) numeric(15, 5) Violation of Interconnector standing data limits
MNSP numeric(1, 0) tinyint Flag indicating MNSP registration
EXPORTLIMIT numeric(15, 5) numeric(15, 5) Calculated Interconnector limit of exporting energy on the basis of invoked constraints and static interconnector export limit
IMPORTLIMIT numeric(15, 5) numeric(15, 5) Calculated Interconnector limit of importing energy on the basis of invoked constraints and static interconnector import limit. Note unlike the input interconnector import limit this is a directional quantity and should be defined with respect to the interconnector flow.
MARGINALLOSS numeric(15, 5) numeric(15, 5) Marginal loss factor at the cleared flow
EXPORTGENCONID varchar(20) varchar(20) Generic Constraint setting the export limit
IMPORTGENCONID varchar(20) varchar(20) Generic Constraint setting the import limit
FCASEXPORTLIMIT numeric(15, 5) numeric(15, 5) Calculated export limit applying to energy + Frequency Controlled Ancillary Services.
FCASIMPORTLIMIT numeric(15, 5) numeric(15, 5) Calculated import limit applying to energy + Frequency Controlled Ancillary Services.
LASTCHANGED datetime(3) datetime2(0) Last changed date of this record
LOCAL_PRICE_ADJUSTMENT_EXPORT numeric(10, 2) numeric(10, 2) Aggregate Constraint contribution cost of this Interconnector: Sum(MarginalValue x Factor) for all relevant Constraints, for Export (Factor >= 0)
LOCALLY_CONSTRAINED_EXPORT numeric(1, 0) tinyint Key for Local_Price_Adjustment_Export: 2 = at least one Outage Constraint; 1 = at least 1 System Normal Constraint (and no Outage Constraint); 0 = No System Normal or Outage Constraints
LOCAL_PRICE_ADJUSTMENT_IMPORT numeric(10, 2) numeric(10, 2) Aggregate Constraint contribution cost of this Interconnector: Sum(MarginalValue x Factor) for all relevant Constraints, for Import (Factor >= 0)
LOCALLY_CONSTRAINED_IMPORT numeric(1, 0) tinyint Key for Local_Price_Adjustment_Import: 2 = at least one Outage Constraint; 1 = at least 1 System Normal Constraint (and no Outage Constraint); 0 = No System Normal or Outage Constraints
