P5MIN_UNITSOLUTION

Comment

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_UNITSOLUTION shows the Unit results from the capacity evaluations for each period of the study.


Description

P5MIN_UNITSOLUTION data is confidential, so shows own details for participant.

Source

P5MIN_UNITSOLUTION updates every 5 minutes for all units, even zero targets.

Volume

Rows per day: 57600

Based on 200 units per Interval

Note

A bitwise flag exists for each ancillary service type such that a unit trapped or stranded in one or more service type can be immediately identified. The SPD Formulation document details the logic determining whether a unit is "trapped" or "stranded". The flag is defined as follows:

Flagged Condition

Bit

Description

Field value

FCAS profile active

0

The bid profile for this service has been activated such that the unit is available to be cleared to provide this ancillary service type.

1 or 3

Trapped

1

The unit is enabled to provide this ancillary service type, however the profile for this service type is causing the unit to be trapped in the energy market.

3

Stranded

2

The unit is bid available to provide this ancillary service type, however, the unit is operating in the energy market outside of the profile for this service type and is stranded from providing this service.

SEMIDISPATCHCAP

NUMBER(3,0)

 

Boolean representation flagging if the Target is Capped

INTERVENTION

Number(2,0)

 

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
