EDS 2 – Scope of Transition Plan Tasks

Tasks Transition Plan Task Descriptions

5.4.1 (2a) Verify all data and telemetry submittals meet Protocol 3.10 (NOMCR)

5.4.1 (2b) Verify accuracy of all transmission element constraints

5.4.1 (2c) Verify TSP calculations for transmission constraints likely to be binding in SCED

5.4.2 (1) Verify SE performance meets Protocol 3.10.9

5.4.2 (2) Verify trial of SE test based on live SCADA, resolving errors to meet performance criteria, and to verify bus load forecast functionality

5.4.2 (4) Begin continuous operation of SCADA and post information to TSPs and QSEs meeting Protocol 6.3.2

5.4.3 (1) Begin NSA verification, testing major transmission elements

5.4.3 (2) Compare NSA to Zonal and add contingencies and screening

5.4.3 (3) Continuously monitor Mon-Fri meeting Protocol 6.5.7.1.11



EDS 2 – Approach– Release 3

• Verify Telemetry and SE performance

• Provide performance reports to TSPs and QSEs

• Verify Network Security Analysis (NSA)

• Develop Maintenance Procedures

– Release 4• Verify Network Model Management System (NMMS)

• Verify Network Operations Model Change Request (NOMCR)

• Develop Network Model Maintenance Procedures



EDS 2 Release 3 - Approach– Telemetry Verification

• Accumulate and calculate monthly and quarterly availability data• Generate reporting per Telemetry Standards

– Highlight and verify availability issues– Provide on MIS for market participants

• Develop ERCOT Operations Procedures to address and resolve issues

– State Estimator Verification • Topology build• Forecast bus load• Nodal SE solution and compares to Zonal• Accumulate and calculate monthly performance data• Generate reporting per SE Standards

– Highlight and verify data issues– Provide on MIS for market participants

• Develop ERCOT Operations Procedures to address and resolve issues



EDS 2 Release 3 - Approach– Topology Consistency Analyzer

• Identify and report on status errors

– Forced Outage Detection• Identify and report on unplanned outages• EDS 3 integrates with the outage scheduler

– Network Security Analysis• Verify dynamic ratings are correctly calculated• Verify overload notification• Verify constraints and contingency list• Verify Special Protection Schemes (SPS) / Remedial Action Plans (RAP):

– Triggering conditions are defined and can be executed– Post-SPS and post-RAP results are correct and can be reported

• Verify load rollover modeling• Verify transmission constraint management (calculate shift factors)• Develop Nodal NSA operating procedures• Benchmark results against Zonal real time operations

EDS 2 Release 4 - Approach– Network Model Management System (NMMS):

• Network model, ICCP database and with ownership / operatorship information

• Nodal Network Model is under change control

– Network Operations Model Change Request (NOMCR)• TSPs and QSEs electronically submit model changes and receive

acknowledgement

• Network model has been correctly updated

• TSP and QSE updates are confirmed

• TSPs may export network model for review

– Single Entry Model– Network Model Export



EDS 2 Release 4 - Systems– Release 4 configuration

• Early releases of software packages

– Network Model Management System (NMMS)

» Database for network model, ICCP mapping, Ownership/Operatorship

– EMS 2.3 (COTS+)

» Integration with NMMS
