2018 Base Case Compilation Schedule1

Introduction

The Data Subcommitteecompiles eleven steady state and dynamic base cases (base cases) to meet WECC’s requirements to compile interconnection-wide base cases.The 2018Base Case Compilation Schedule provides base case descriptions and a schedule for base cases to be compiled during the 2018calendar year.

Objectives

The objectives of the 2018Base Case Compilation Schedule are:

Provide a detailed schedule, to appropriate stakeholders, identifying necessary data submittals and data review milestones to compile eleven bases cases.
Identify bases cases to be compiled.A typical annual base case compilation schedule includes the following base cases:
Five operating cases
Two scenario cases
One 5-year summer planning case
One 5-year winter planning case
One 10-year summer planning case
One 10-year winter planning case

Supporting Information

Timely submittal of steady state and dynamics data is necessary forthe 2018Base Case Compilation Schedule to be maintained. In the event of delayed steady state and dynamic data submittals, the Data Subcommittee will follow the Late Data Procedure provided in the WECCData Preparation Manual.

Typical base cases are intended to model anticipated load levels, but in some instances may model slightly heavier or slightly lighter than anticipated load levels to achieve desired stressed transfer levels on designated paths.Typical base cases usually include operating cases, five-year cases, ten-year cases, and additional cases as requested by the RAC membership.Scenario base cases are intended to represent critical operating conditions such as severe weather events, equipment out of service (transmission lines, reactive devices, or static var compensators), unusual generation patterns due to forced outages, and insecure voltage conditions.Some cases may represent extreme load conditions (up to 105 percent of forecasted peak) in a particular sub-region. Data submitters should not be reluctant to model a condition due to lack of historical record of the scenario actually occurring.

The 2018Base Case Compilation Schedule includes the following base cases:

Typical base cases
Operating base cases
2018-19Heavy Winter
2018-19Light Winter
2019Heavy Spring
2019Heavy Summer
2019Light Summer
Five-year base cases
2024Heavy Summer
2023-24Heavy Winter
Ten-year base cases
2028-29Heavy Winter
2029Heavy Summer
Scenario base cases
2029 Heavy Spring with mid-day load and high renewable generation
2019 Light Spring with 50-60% of peak load and high renewable generation

Generation and load levels referred to in the base case description sheets refer to the season being studied.For example, if a case description sheet for a winter base case calls for high hydro in a specific area, this means high levels of hydro generation for a winter condition.In some areas, a high level of hydro generation in the winter may be less than median hydro generation levels in the spring or summer. Also, light loads may be increased in the importing areas or heavy loads may be decreased in exporting areas to represent the desired interchange schedules.Renewable generation, when specified, should be based on individual entities’ Renewable Portfolio Standard. Specific information on the desired load levels is contained in the base case description sheets and should be used as a guide in preparing cases. All loads are coincident unless indicated otherwise. Specified time supersedes specified percentage of load.

Interchange Schedules in the base case description sheets refer to the target flows that should be reached to represent anticipated flow levels and direction for the season being studied.Targets may be altered as anticipated operating conditions become more clearly known. Where no target flows are specified actual scheduled transfers should be based on each area’s load and generation (deficiency/surplus) balance and economical generation dispatch. The purpose of the case should be kept in mind and schedules should be coordinated between areas prior to data submittal.

Only corrections to the Master Dynamics File (MDF) or new data for the MDF need be submitted for each case build.

During the process of compiling each base case, WECC staff and the appropriate functional entities participating in base case compilation process should follow the data requirements and procedures outlined in the WECCData Preparation Manual.Following the documented requirements and procedures will contribute to developing base cases with compatible steady state and dynamic data, help to ensure the Interconnection-wide Model is adequately modeled, and aid in continual improvement in the accuracy of the data submitted.
