WECC Survey: Implementation of Planning Standards 1.D.” Reactive Reserve Working Group August 15-17 TSS Meeting
Outline • Background • Survey Overview • Results • Recommendations
Background “…..(RRWG) will resurrect the reactive survey, and investigate if the standards on reactive studies should be applied to individual entities, to the balancing authority, or applied based on other criteria “ Section 14, Meeting #142 Minutes (March 29th, 2006 TSS Meeting)
Background • Planning Standards 1.D. - System Adequacy and Security/ Voltage Support and Reactive Power • Survey Request sent out Oct. 17, 2006 to PCC – only 15 respondents • Follow-up request sent only to Transmission Providers (TP1 and TP2) represented at TSS – Feb 16, 2007 • New Deadline March 8, 2007
Survey Overview • 23 out of 71 eligible entities responded = 33% (There may have been a few late responses which are not included in the results) • 16/23 of those responded (70%) assessed their transmission system against Planning Standard 1.D. • 3/23 indicated other planning authorities (CAISO, WAPA and SCE) that undertake these on their behalf • 4/23 indicated that they didn’t assess their transmission system at all
Results • 16/23 of those responded (70%) assessed their transmission system against Planning Standard 1.D. • 3/23 indicated other planning authorities (CAISO, WAPA and SCE) that undertake these on their behalf • 4/23 indicated that they didn’t assess their transmission system at all
Results • Reasons for not assessing transmission system against Standard 1.D. Given: • Manpower constraints • Minimal system growth – does not require a study • Two respondents did not give reasons
Results • PV Methodology Followed by 10 / 16 (63%). Reasons for not following PV Methodology: • Entities have their own methodology • Waiting to Install software to conduct PV analysis • PV not required – VQ adequate (2/7 indicated this)
Results • V-Q Methodology Followed by 8 / 16 (50%). Reasons for not following V-Q Methodology: • PV adequate (5/8 felt this way) • Entities with own methodology • One respondent indicated that they operate to 0 reactive margin (i.e., no reactive margins)
Results “…..(RRWG) will resurrect the reactive survey, and investigate if the standards on reactive studies should be applied to individual entities, to the balancing authority, or applied based on other criteria “ Section 14, Meeting #142 Minutes (March 29th, 2006 TSS Meeting)
Recommendation • The voltage stability standard should not apply to the Balancing Authority as defined by the NERC Functional Model Version 3
