• WECC’s tool to create base cases• BCCS is a database with a few extraso Starts from “Master Base Case”

Existing system (Topology)

o Holds various load and generation patternso System additions or correctionso Has the ability to solve a case

What is BCCS?

Steady-State Dynamics (not used at this time in the BCCS) WECC

o Generation and Transmission/Load Planned Proposed Exploratory

Project Files (cont.)

8

• Download Base Case out of BCCSo Import and solve case in the desired Powerflow

program o Export solved case and save for comparison

• Add project to caseo Solve and Save case (save with different

name)o Export raw file and save file

• With these two raw files you can make a project file in File Builder

Creating a Project file

• Administrative Functions• Uploading• Downloading • Viewing data on the web• Editing data on web• Building Cases

BCCS Web Interface

11

• Login• User settings and options• Email from BCCS• Downloading

Web Interface: Administrative Overview

12

• Logino Login on the web at https://bccs.wecc.biz o Internet Explorer is only supported browser

Other browsers work but layout looks wrong

• My Accounto Preferences

Able to see type of data you can change, assigned areas, assigned project types, and adjust user profile

Web Interface: User Administrative Functions

13

• My Account Continuedo Suppress or allow emails

“Send me email notifications” check box

o 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

Web Interface: User Administrative Functions continued

14

• Groupso Decide what data can be modified

Based on Bus Number Range Owner Numbers Zone Numbers Area Numbers

• Roleso Decides what actions you are allowed to

perform Modify, View, Approve…

Web Interface: User Administrative Functions continued

15

• Several email categories (ptimod.admin@siemens.com) o 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)

o Project and Profile Approval Multiple layers of approval (Submit, Approve, and

Accept)

Web Interface: Email Notifications

16

• How to uploado Projecto Profileso Alternate caseso Net Scheduled Interchangeo Applying to data request

• Downloading

Uploading/Downloading

17

• Create project using MOD FileBuilder• Select import on the project page or on the

tree menuo Browse to project location on local machineo Click Send

• Must verify project type and status are completed fields

Uploading a Project

18

• Make sure any validation issues are addressedo 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

Uploading a Project Cont.

19

• Create profile using MOD FileBuildero Type of profile decides how it should be

handled. o WECC Staff will create a “base profile”

Data submission will apply to the specific “base profile”

o May need specific types for profiles to identify Have not been developed yet

Uploading a Profile

20

• Select import on the profile page or on the tree menuo Browse to project location on local machineo Click Send

• Validationo Examine that profile changes are made only in

assigned area

Uploading a Profile Cont.

21

• What is a Alternate Base Case?o Optional tool for case creationo Used only in case definitiono May require different set of projectso Primarily used by users, not likely to be used

for WECC approved case creationo Can be uploaded with PSLF .SEQ data

Negative and zero sequence data for fault analysis

Uploading Alternate Base Cases

22

• Select import on the Alternate Base Cases page or on the tree menuo Browse to project location on local machineo Click Send

• Alternate base case has basic table views just as the base case does to be discussed next

Uploading a Alternate Base Case Cont.

23

• Main page of BCCS provides Equipment summary

• Tree menu can be expanded to show list of tableso Bus, branch, load, generator,… o The list includes both data common between

PSFL and PSS/E as well as tables found only in each program.

Viewing Base Case

24

• Useful for anyone without access to a power flow programo Others unlikely to use the viewing capabilities

extensively

• Tables navigated through tree menu or list menu at the bottom of each tableo Limited number of records per pageo Filtering is provided

• Base case not directly edited

Viewing Base Case Continued

25

• 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 projectso This takes you to the high level project page

• To view specifics of a project choose the phase and view

Viewing Projects

26

• Projects are broken into the tables they changeo For example: to view bus changes select Bus

from the menu at base of screeno 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

Viewing Projects Continued

27

• 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 datao For example: BLG profiles

Bus, load, and generation data listed in tables

Viewing Profiles

28

• Select alternate base case from the tree menu on left

• Select the alternate base case you wish to viewo Select view on the bottom of the screen

• Very similar to viewing the base caseo No tree menu on the side of the screen

Viewing Alternate Base Case

29

• Download the base case for project file creation

• On home screen below equipment listo Select Download Base Case

• Alternate Option:o Build a case with no projects or profiles

Downloading Base Case

30

• Select Projects from the tree menu• Select the project you want to download

from the listo This will highlight the line

• Select download (it has been observed that this does not work) o Can also be done for each phase of the project

Downloading a Project

31

• Project selectiono When WECC builds a case we will include all

the approved projects up to the date of the case being build

o 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 selectiono Only one profile may be used for each case

build

Building Cases

32

• Case build ordero This is handled outside of the online applicationo If not being applied as expected we can adjust

• Ratings applied to caseo 8 Ratings for PSLF users (Want all 8

populated)o PSS/E 3 Rating selected

PSS/E users will need different ratings profiles for each year and season based on the case description

Building Cases

33

• Why have an approval processo Catch data errorso Data qualityo Verify that data (projects) should be in base

cases

• Who performs the approvalo Initial Submitter (Data Owner, sub-coordinator)o Approve Data (Area Coordinator)o Accept Data for Case (Staff)

Approval Process

34

• What happens after approvedo Project will included in WECC case buildso Considered “good data”

• Editing projects after they have been approvedo Will restart the approval process

• Committing a projecto Added to the master base caseo No longer a “project”

Approved Project

35

• WECC base case profile processo Changes to Base Profile must go through

approval processo Different profiles will have different approvals

Example: Net Scheduled Interchange profiles will be different than the BLG profile

• Independent case/Profile creationo Can build profiles for own use and case builds

Will not go through the approval process

Profiles

36

• Profile approval processo After creation in MOD FileBuildero Submit to BCCSo Validation will be run

Verify only changing “your” data Based on Group that responsible for

• Base Profile creation and Modificationo WECC Staff will create a base profile for each

base caseo Will be modified by data owners

Profiles continued

37

• Deleting data has an approval processo A request is created when delete is selected by

a user with permission to delete If confirmed it will proceed to the next step

o A request is sent to the approver If approved sent to next step

o 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

Deleting Data (Projects or Profiles)

38

• Data requests can specify type of data requesto Profileso Projects

• Data submissiono Apply data provided through uploading to

various data requestso Done through web interfaceo Manual process

Data request from BCCS

39

• Select Data Submission Request from the tree menuo Will list the data requests applicable to your

groupo When data is applied to the request it will show

the submission Allows tracking for data Will create the late data log Automatic email reminders are sent daily after due

date passes

Data Submission

40

• WECC staff administrative supporto User names requestso Forgotten passwordso Website issues

• Area Coordinatorso Received Training from Siemenso Primary support on MOD FileBuildero Primary approval, Data Checking

Support

41

• Verify that we can build the “same” case in both processeso This will require extra timeo 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

o Will do as many cases as it takes to build confidence in and improve the process

Parallel Process for Building Cases

42

• Should be two update processeso Normally static data* (e.g., impedances,

dynamics data)o 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

BCCS Process

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

• “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

Operationally Variant Data Collection Process

46

Operationally Variant Data Collection Process

47

• As we use the tool the process will evolveo What workso What is more difficulto Changes that would make the process better

To the BCCS To the process

• SRWG and the Data Preparation Manualo Will be updated with the processo Maintained at SRWG
