ADSTF ISSUE LIST - PF2 Problem Statement - What data (specifically) from the 2028 HS1 power flow case will be used to populate the PCM ADS dataset? The WECC Reliability Assessment Committee’s (RAC’s) Anchor Data Set Task Force (ADSTF) formed a task group comprised of Jamie Austin, Andrew Christensen, Radha Soorya and Ron Schellberg to respond to question PF 2 on the Anchor Data Set Implementation Questions, dated November 1, 2017. Discussion: The Western Planning Regions (WPRs) developed the flow and 2026 2026 “power seed case,” “Production Cost Model (PCM) seed from 2026 PCM Common Case and their individual case” derived WECC’s planning region data. As indicated by WPRs these power flow and PCM seed cases represent their regional plans as developed through their Order 1000 regional processes. To create the 2028 Anchor Data Set (ADS), WECC issued a data request to its Data Submitters for submission of data for 10 year case consistent with WECC data collection procedures and the WECC Data Preparation Manual (DPM). WECC and WPRs recommended that the 2026 flow seed should “power case” serve as the starting point or reference for the Data Submitters when developing the 2028 Heavy Summer Case where the additional resources, loads and topology for next two years should be added to each of their area. WECC is in the process of developing and finalizing 2028 Heavy Summer power flow case based on the data submissions through their MOD 32 and base case development process. The extent to which the 2028 Heavy Summer power flow case changes the resources and transmission topology included in the 2026 seed cases is currently unknown. The purpose of this paper is to conduct difference analysis between the 2028 Heavy Summer power flow case and 2026 Powerflow Seed Case to determine the case differences. Analysis and Observations: Initial analysis by the task group indicated that there are no significant topological differences between the 2028 HS1 and 2026 Seed Case. Following table summarizes the high-level equipment differences in both the cases. The major difference of significance to synchronizing the two data sets is the generation data therefore the following analysis is focused in this area. Note, other topological changes will be implemented from the 2028 HS1 case in the production cost model, using the “Round trip”.
