PDPASA
The PDPASA package provides a 30-minute solving process to the Market systemsThe current methodology for calculating reserves in the PreDispatch timeframe is determined in a post processing step using a heuristic calculation based the results and Interconnector limits from the PreDispatch run.The calculation is a reserve assessment based on the PASA solver similar to existing ST and MT PASA business processesThe process reflects all intra-regional and inter-regional network constraints as an input to the process
Tables
This package contains the following tables:
| Name | Description |
|---|---|
PDPASA_CASESOLUTION |
The top-level table identifying a PDPASA case, reporting options applied in the case and summary results |
PDPASA_CONSTRAINTSOLUTION |
PDPASA_CONSTRAINTSOLUTION shows binding and violated constraint results from the capacity evaluation, including the RHS value. |
PDPASA_DUIDAVAILABILITY |
This report delivers available capacity, PASA availability and given recall period for all scheduled resources. Note that for an MNSP, DUID = LINKID in the MNSP_INTERCONNECTOR table. |
PDPASA_FNM_CASESOLUTION |
PDPASA_FNM_CASESOLUTION shows the case run details, including the available run types, LOR and Deficit condition for each case. |
PDPASA_FNM_CONSTRAINTSOLUTION |
PDPASA_FNM_CONSTRAINTSOLUTION shows manual or thermal constraint (created by PASA), including marginal value, violation degree, LHS and RHS. |
PDPASA_FNM_DUIDAVAILABILITY |
PDPASA_FNM_DUIDAVAILABILITY shows Available Capacity, PASA Availability and Recall Period for all scheduled resources |
PDPASA_FNM_INTERCONNECTORSOLN |
PDPASA_FNM_INTERCONNECTORSOLN shows cleared Interconnector flow for the interval. |
PDPASA_FNM_INTERZONALSOLUTION |
PDPASA_FNM_INTERZONALSOLUTION shows cleared inter zonal flow for the interval and run type. |
PDPASA_FNM_REGIONSOLUTION |
PDPASA_FNM_REGIONSOLUTION shows region demand, cleared values of resources, spare capacity, losses for each run type and intervals. |
PDPASA_FNM_REGIONSUMMARY |
PDPASA_FNM_REGIONSUMMARY shows the summary of PDPASA outcome for each region. |
PDPASA_FNM_ZONESOLUTION |
PDPASA_FNM_ZONESOLUTION shows zone demand, cleared values of resources, spare capacity, losses for each run type and intervals. |
PDPASA_FNM_ZONESUMMARY |
PDPASA_FNM_ZONESUMMARY shows the summary of PDPASA outcome for each zone. |
PDPASA_INTERCONNECTORSOLN |
PDPASA_INTERCONNECTORSOLN shows the results of the capacity evaluation for Interconnectors, including the calculated limits for the interval. |
PDPASA_REGIONSOLUTION |
The PDPASA region solution data.Note that the OUTAGE_LRC Run Type is no longer reported from 31 July 2025. |
