Meeting Report WP1.2 ‘Modelica library for MPC’

1. MEETING SUBJECT, DATE

Subject: WP1.2

Date: 01-06-2020

Location: Skype for Business

Minutes taken by: Lieve Helsen (KU Leuven)

2. PARTICIPANTS

3. AGENDA and REPORT

3.1. Approval/Modification Agenda

Approved

3.2. Status & further discussion where needed

a. Emulators:

4 models selected to start MPC testing

i. BESTEST Air (LBNL/KU Leuven):

merged to the master – READY! (Dave)

ii. BESTEST Hydronic (KU Leuven /LBNL):

ready for merging – ALMOST READY! (Filip)

iii. 8-Zone Residential Hydronic (Engie/SDU):

In pull request, update needed for zone identifiers (Javier).

iv. Multi-Zone Office Hybrid Simple (KU Leuven/Engie):

Managed to compile the model with JModelica, simulation with JModelica does not run (action Iago/Javier). Have a look at the solvers used.

However further progress has been made in other models too!

v. Single-Zone Commercial Building (SDU/LBNL):

Tao is processing the feedback from Dave.

vi. Multi-Zone Air-Based Prototype Complex (PNNL/KU Leuven):

Iago gave feedback, occupancy profile is missing. To be processed by Sen. No update.

vii. Flexible Research Platform (ORNL/SDU):

Yeonjin is working on the control part now 10 zones office with VAV system.

Emulators need to be put on BOP-TEST repository in the directory `testcases`.

Emulators overview:

b. KPIs - scenarios

Choice between TMYx (1946-2018) and TMY3 (1973-2005) weather files. We have a data reader for TMY3 in IBPSA. Both will be compared in the representative days/weeks selection (action PNNL). Sen No update.

c. BOPTEST:

i. Test case peer review document:

Update sent by Dave on May 20. No remarks.

ii. Upgrade to Python 3:

Dave is working on new version in Docker container that uses Python 3 and PyFMI (which can be installed easily), no JModelica-compiled image needed anymore; unit tests are going on now. We do not see the need to support Python 2 nor to provide backwards compatibility for it.

iii. Generation of new weather files based on historical data:

to be used for grey and black box model identification (training data that differ from test data). No further progress (Dave).

iv. Working group on weather prediction uncertainties (Aritz):

Autoregressive model based on measurements and Q-Q mapping have been tried. Behaviour of the standard deviation is being studied now to judge whether the method is appropriate, to be continued.

v. BS2021 Conference:

1. Contest? Target control or AI community rather than BS community (Jan will connect and make a first proposal for paper/presentation/workshop to make BOPTEST visible, https://www.climatechange.ai).

2. Workshop? Introducing BOPTEST in Summer 2021 (follow-up of paper at BS2019 in Rome), inspiration towards use cases such as: training building operators, assist teaching ... to be discussed in break-out session (all)

3. Paper? Rather go for a journal paper before BS2021.

d. MPC Library (IbpsaMpc):

i. Unit testing framework (Dave):

No update.

e. Dissemination:

Broaden the user space (e.g. to Machine Learning people). How to reach these people? Jan: make a first suggestion. Cfr OpenAIGym, to be combined with first proposal for paper/presentation/workshop (see 2.c.v.1).

3.3. Initiatives joint papers

a. MPC Review paper: submitted.

3.4. Next phase

a. Finalize first set of emulators!

b. Start testing your controller(s) on the emulators and share your comments, remarks, suggestions for improvement.

c. In the meantime the development of the remaining emulators can continue.

3.5. Miscellaneous

a. Break-out sessions definition for next IBPSA Project 1 meeting (Lieve)

i. Spreadsheet for internal reporting of BOPTEST test cases

ii. Public reporting (limited information, end-user agreement)

iii. MPC competition: how to set up?

iv. How to deal with uncertainties: forecast of weather, loads, occupants?

v. Workshop introducing BOP-TEST at BS2021 (September 2021), as a follow-up of paper at BS2019 in Rome, incl. inspiration towards use cases such as: training building operators, assist teaching ...
