Mark Laufenberg, Ph.D.

ext. 10

2. Project Tasks
Software Modifications
User Workshops

3. Software Modifications
Some new features
Opening substation contingency actions
Injection group load dropping actions
Adding “time delay” to contingency elements and defining order to occurrence of actions
Modifying injection group “open” actions to specify whether or not to exceed the requested flow
Adding contingency action to change resistance of DC line
Total fixed cost of all these together: $19,440

4. Software Documentation
Updating RAS specification document to include all software enhancements.
Document on our public website, continually updated
Also – “If PowerWorld identifies the need for additional software enhancements, PowerWorld shall notify WECC of the need and provide an estimate of the cost needed to implement the specified additional features.”
Software Features are added on a cost-sharing basis at a reduced fee based on $135/hr

5. Implementation of RAS Models: WECC Utility Staff
The only folks fully qualified to describe a utility’s RAS are the engineers who maintain and design the RAS for their system.
There must be engagement by WECC utility staff on this project
PowerWorld Corporation staff is here to help jump start the process, but utility staff needs to participate because they have the knowledge

6. Implementation of RAS Models: User Workshops
Initial two hour webinar
April 2, 2015, 9 am – 11 am MDT.
Goal is to motivate interest in folks to sit down and start modeling their RAS
First 2-day workshop at WECC Office
May 27, pm through May 29, Noon MDT
First day will be classroom training on what these RAS models can do
Second day will be break-out sessions with WECC members implementing their actual RAS together
At the discretion (and scheduling) of WECC, possibility of second in person workshop and a follow up webinar will occur

7. Contractual Flexibility for WECC– Ability to Cancel
Go back to earlier presentations by PowerWorld over the past several years on how effective software development projects work
Small projects with short time-frames
Small means very small:
Features so far have been between 4 hours and 60 hours
Don’t think of this as one big project
It’s really a bunch of small projects all under one contractual framework
Give WECC staff flexibility in assigning tasks
This can be cancelled at WECC’s sole discretion at any time
