[empty2d.zip](https://github.com/Pyomo/pyomo/files/1486275/empty2d.zip) The attached files have an example of an AMPL-format dat file with an empty 2 dimensional set that results in an error. A potential fix that seems like it...

[2dDat.zip](https://github.com/Pyomo/pyomo/files/1486067/2dDat.zip) The attached example has a 2d set with the correct syntax for AMPL in the dat file, but this is the result (at a minimum the message should indicate...

There are number of hours in RTS_Data/timeseries_data_files/WIND/DAY_AHEAD_WIND.csv that have unreasonably high forecast errors. The worst two hours are Date, Time, Forecast, Observed total (from REAL_TIME_wind.csv) 2020-02-27, 19:00:00, 0.1, 1918.03333333333 2020-03-05,...

It would be a nice feature if Egret supported matpower bus type 4, which is an isolated bus.

The path in the file name construction line in acopy.py main should be: matpower_file = os.path.join(path, 'tests/transmission_test_instances/pglib-o pf-master/', filename)

If the nonant Vars differ by scenario we should issue an error
