OpenSG Sim WG: 
3/8/2011 - Face2Face meeting at OpenSG in San Francisco (along with phone conference)

Admin
  - there were phone issues so Craig used the chat window for 
    addressing questions/comments from members on the phone conference
  - expect sharepoint site available in 1 - 2 weeks

  - Aaron mentioned the ability to record the audio portion of meetings

5) With Mack MacKenzie's resignation as co-chair nominations are open until 3-15-2001

6) Survey of Models/Tools by Steffen, ...
   - initial sketch posted to reflector
   - quick and highlights by Craig
     - typology of models/tools
     - survey to be developed by OFFIS

   - presentation by Jason
     - Power System Reliability Models
       ( see slides )

     question about customer interaction?
     J: highly dependent on the time scale of action
        system reliability & economics are tied

     Craig cites Mack's inspiration in approaching modeling & simulation
           and   the co-simulation work done by Roger, Jason, and Tim (in attendance)
           and   the rise of new edge device

     Tim mentions both the simulated voltage drop and subsequent rise in distribution feeders
     with high PV penetration rates and cloud covering behavior 

     Q: about distributed decision making? time frame? scope?

     Craig:
        are API's too specific for our charter
        Agent-based modeling? ... aggregate behaviors

        what's the right architecture

        considerations when incorporating distributed storage

        combinability of models
          STAT-VAR compensators

        how to advise vendors?

     mention of Models & Simulations in other industries

     Jason: Controls behavior necessitates modeling/simulation of communications

     Craig: Extending the utility range of technology/product trials beyond 'hard' trials

     Martin: How are Geographic Considerations incorporated?
             - Jason: typically be choosing the realm of interest and thus the scope of interaction

     Craig/Jason: Analytic models - require run to completion analysis
                  which is a mismatch in event timestep analysis

                  - don't know what happened where & when

     Suggestion/response for a Glossary - terms and concepts
       - Power Systems "Security"
         - ability to continue delivery of electricity (system stability in the face of failures)
         - physical/ICT security

     Aaron: Any specific meaning to the Encapsulation of Distribution within Transmission within Generation?
     Jason: Not modeling specific , represents the historical constaints ...
            ... without Generation then no transmission; without Transmission then no Distribution

            Renewed change vectors: increasing reliability in Distribution: distributed generation/storage
                                    Transmission/Distribution - IEEE 1547: (Anti)Islanding

     Jason: Agent-based modeling: a common approach in assessing aggregate behavior

     Q: underlying mathematical characterstics?
     A: example of EVs as Quasi-static loads and integrating probabilistic approaches
          (driving habits/state of charge/charging time & durations)

     Craig: reminder from Erich in his email about the importance of the empirical 
           
          : sensitiviy of models (eg. climate change models)
            (vs. 100 years of historical, accretive practice)

          : the new new of adaptive, distributed control

            - eg. from cell phone modeling/simulation/design points
               - statistically most calls are intersite not intrasite (callers not on same cell tower)
               - sized for 256/512 concurrent calls
               - mismatch when applying to communication traffic pattern of cellular based 'smart' meters/AMI
                 - 1000s intrasite


Deliverables:

  Craig: Rev2A
         Model Decomposition (Mack)
         need to review, revisit this

  Aaron: SRS (System Requirements Specification)

         view Paper on Model Decomposition as complimentary with SRS (sets context of/for SRS)

  Martin: perhaps we (Craig) can convince Mack to give a presentation

  Craig: yet another call to recruit colleagues into our efforts

9) next F2F (Vancouver: 7/18-21)
