Examples

Sample scripts are distributed with the pyaeso source in the examples directory. These show how pyaeso might be used to build useful utilities and publication quality postscript, pdf, or raster graphs that could be used for books or for automated web applications.

Currently distributed sample scripts are:

• list_participants.py - prints a list of market participants.
• simple.py - prints market equilibrium points for previous day.
• marginal_prices.py - prints marginal price points for present and previous day.
• print_gen_output.py - prints current output of Alberta power generators.
• print_aieslog.py - prints snapshots of the Alberta Interconnected Electric Sysem (AIES) Event Log.
