DISPATCHCASESOLUTION_BNC was discontinued on 30 September 2009. In accordance with the "Arrangements for Managing Risks Associated with Transmission Network Congestion" set of rule changes the Dispatch Binding Network Constraints re-run was discontinued on September 30, 2009. Source The occurrences of Over-constrained dispatch (OCD) or binding intra-regional network constraints (BNC) re-runs are ad hoc, with significant dependencies on the configuration or events in the physical power system. Potentially updated every 5 minutes. Volume Rows per day: ~72 Mb per month: 25% of DISPATCHCASESOLUTION The estimates on the number of rows are based on a 25% occurrence rate for BNC runs. Note Due to the close dependency with the dispatch process, the OCD and BNC data models use a “CaseSolution” key table in the same manner as DISPATCHCASESOLUTION. |
