Base Case Process Discussion and Review

3. What is BCCS? WECC’s tool to create base cases
BCCS is a database with a few extras
Starts from “Master Base Case”
Existing system (Topology)
Holds various load and generation patterns
System additions or corrections
Has the ability to solve a case
SAT Testing
Interactive training
Identify any issues
If we need more time please ask and keep this going
Siemens support

How to Create a Project File
Select the Project Function
Create Project – Select a name
Project Header
Open Base Case – Does not Include project
Open New Case – Includes changes
Compare all or by Criteria
Area
Owner
Zone
DMP Checks
Review

8. Creating a Project file
Download Base Case out of BCCS
Import and solve case in the desired Powerflow program
Export solved case and save for comparison
Add project to case
Solve and Save case (save with different name)
Export raw file and save file
With these two raw files you can make a project file in File Builder

9. Profiles Files What is a Profile File? Naming Convention
Rating Profile
Bus Load and Generation Profile

Editing data on web
Building Cases

11. Web Interface: Administrative Overview
Login
User settings and options
from BCCS
Downloading

12. Web Interface: User Administrative Functions
Login
Login on the web at
Internet Explorer is only supported browser
Other browsers work but layout looks wrong
My Account
Preferences
Able to see type of data you can change, assigned areas, assigned project types, and adjust user profile

13. Web Interface: User Administrative Functions continued
My Account Continued
Suppress or allow s
“Send me notifications” check box
See group name and role assigned as user
The actions you can perform are listed under the role
If you can’t perform an action this is the first place to look

14. Web Interface: User Administrative Functions continued
Groups
Decide what data can be modified
Based on Bus Number Range
Owner Numbers
Zone Numbers
Area Numbers
Roles
Decides what actions you are allowed to perform
Modify, View, Approve…

15. Web Interface: Email Notifications
Several categories
Data Submittal Requests
Data requests are assigned to user groups
Initial Data Submittal Request
Type of data requested (projects or profiles)
Reminder (request creator can designate how often)
Past Due Date (daily notifications)
Project and Profile Approval
Multiple layers of approval (Submit, Approve, and Accept)

16. Uploading/Downloading
How to upload
Project
Profiles
Alternate cases
Net Scheduled Interchange
Applying to data request
Downloading

17. Uploading a Project Create project using MOD FileBuilder
Select import on the project page or on the tree menu
Browse to project location on local machine
Click Send
Must verify project type and status are completed fields

18. Uploading a Project Cont.
Make sure any validation issues are addressed
If the change is legitimate but results in a warning
Comments can be used to help any approval so contact is not needed
Ensure the effective date is correct for each phase
Once all validation issues are addressed submit the project

19. Uploading a Profile Create profile using MOD FileBuilder
Type of profile decides how it should be handled.
WECC Staff will create a “base profile”
Data submission will apply to the specific “base profile”
May need specific types for profiles to identify
Have not been developed yet

20. Uploading a Profile Cont.
Select import on the profile page or on the tree menu
Browse to project location on local machine
Click Send
Validation
Examine that profile changes are made only in assigned area

21. Uploading Alternate Base Cases
What is a Alternate Base Case?
Optional tool for case creation
Used only in case definition
May require different set of projects
Primarily used by users, not likely to be used for WECC approved case creation
Can be uploaded with PSLF .SEQ data
Negative and zero sequence data for fault analysis

22. Uploading a Alternate Base Case Cont.
Select import on the Alternate Base Cases page or on the tree menu
Browse to project location on local machine
Click Send
Alternate base case has basic table views just as the base case does to be discussed next

23. Viewing Base Case Main page of BCCS provides Equipment summary
Tree menu can be expanded to show list of tables
Bus, branch, load, generator,…
The list includes both data common between PSFL and PSS/E as well as tables found only in each program.

24. Viewing Base Case Continued
Useful for anyone without access to a power flow program
Others unlikely to use the viewing capabilities extensively
Tables navigated through tree menu or list menu at the bottom of each table
Limited number of records per page
Filtering is provided
Base case not directly edited

25. Viewing Projects Navigate to the projects page from the tree menu
Select project you would like to view and select the view button at bottom of list of projects
This takes you to the high level project page
To view specifics of a project choose the phase and view

26. Viewing Projects Continued
Projects are broken into the tables they change
For example: to view bus changes select Bus from the menu at base of screen
Changes are on the phase level, entire project changes are not seen in web interface
Useful to verify that the project was read in correctly

27. Viewing Profiles Navigate to the profiles page from the tree menu
Select profile you would like to view and select the view button at bottom of list of profiles
Specific profiles show specific data
For example: BLG profiles
Bus, load, and generation data listed in tables

28. Viewing Alternate Base Case
Select alternate base case from the tree menu on left
Select the alternate base case you wish to view
Select view on the bottom of the screen
Very similar to viewing the base case
No tree menu on the side of the screen

29. Downloading Base Case Download the base case for project file creation
On home screen below equipment list
Select Download Base Case
Alternate Option:
Build a case with no projects or profiles

30. Downloading a Project Select Projects from the tree menu
Select the project you want to download from the list
This will highlight the line
Select download (it has been observed that this does not work)
Can also be done for each phase of the project

31. Building Cases Project selection Profile selection
When WECC builds a case we will include all the approved projects up to the date of the case being build
Users will have the option to build cases
Can include other projects or exclude some approved projects depending on the use of the case
Profile selection
Only one profile may be used for each case build

32. Building Cases Case build order Ratings applied to case
This is handled outside of the online application
If not being applied as expected we can adjust
Ratings applied to case
8 Ratings for PSLF users (Want all 8 populated)
PSS/E 3 Rating selected
PSS/E users will need different ratings profiles for each year and season based on the case description

33. Approval Process Why have an approval process
Catch data errors
Data quality
Verify that data (projects) should be in base cases
Who performs the approval
Initial Submitter (Data Owner, sub-coordinator)
Approve Data (Area Coordinator)
Accept Data for Case (Staff)

34. Approved Project What happens after approved
Project will included in WECC case builds
Considered “good data”
Editing projects after they have been approved
Will restart the approval process
Committing a project
Added to the master base case
No longer a “project”

35. Profiles WECC base case profile process
Changes to Base Profile must go through approval process
Different profiles will have different approvals
Example: Net Scheduled Interchange profiles will be different than the BLG profile
Independent case/Profile creation
Can build profiles for own use and case builds
Will not go through the approval process

36. Profiles continued Profile approval process
After creation in MOD FileBuilder
Submit to BCCS
Validation will be run
Verify only changing “your” data
Based on Group that responsible for
Base Profile creation and Modification
WECC Staff will create a base profile for each base case
Will be modified by data owners

37. Deleting Data (Projects or Profiles)
Deleting data has an approval process
A request is created when delete is selected by a user with permission to delete
If confirmed it will proceed to the next step
A request is sent to the approver
If approved sent to next step
A request is sent to the accepter
If accepted the data is removed from the active list
Deleted data is not eliminated and can still be viewed

38. Data request from BCCS Data requests can specify type of data request
Profiles
Projects
Data submission
Apply data provided through uploading to various data requests
Done through web interface
Manual process

39. Data Submission Select Data Submission Request from the tree menu
Will list the data requests applicable to your group
When data is applied to the request it will show the submission
Allows tracking for data
Will create the late data log
Automatic reminders are sent daily after due date passes

40. Support WECC staff administrative support Area Coordinators
User names requests
Forgotten passwords
Website issues
Area Coordinators
Received Training from Siemens
Primary support on MOD FileBuilder
Primary approval, Data Checking

41. Parallel Process for Building Cases
Verify that we can build the “same” case in both processes
This will require extra time
Likely two data requests
One for data to be sent to Area Coordinator and Sub Coordinators as usual
One for data to be submitted to BCCS
Will do as many cases as it takes to build confidence in and improve the process

42. BCCS Process Should be two update processes
Normally static data* (e.g., impedances, dynamics data)
Operationally variant data (e.g., generator dispatch for a specific scenario)
Two processes have different update cycles
*Note: This process will change after initial population of the BCCS

43. Normally Static Data Collection Process (Implementation Phase)
Primarily:
“Project” Files
Ratings Files
Dynamics Data

44. Normally Static Data Collection Process (Ongoing Process)
Data provided “as needed”
No official data request – similar to current process for Generator Testing Program

45. Operationally Variant Data Collection Process
“Profile” information (loads, generation, reactive devices, interchange, etc.)
Data request for each base case data set
Similar to current base case development schedule
Data provided from a solved case
Includes initial submittal and data review periods

46. Operationally Variant Data Collection Process

47. BCCS Process As we use the tool the process will evolve
What works
What is more difficult
Changes that would make the process better
To the BCCS
To the process
SRWG and the Data Preparation Manual
Will be updated with the process
Maintained at SRWG
