Pythonic access to the Alberta (Canada) Electric System Operator (AESO) Energy Trading System (ETS).
pyaeso is a python package that makes access to the Alberta, Canada, Electric System Operator’s (AESO) Energy Trading System (ETS) easier.
The Alberta Electric Systems Operator (AESO) <http://www.aeso.ca> operates Alberta’s deregulated electricity market. AESO provides price, demand, and other valuable information through the publically accessible Energy Trading System (ETS) website <http://ets.aeso.ca>. This information is useful for economic analysis, power trading, electric system study, and electric system forecasting. The first step in using such information is to download it and parse it into useful data structures - a task performed by this library. Typically the data will feed statistical methods, heuristics, and system models to provide useful analysis of the Alberta electric system.
The pyaeso project is hosted at <http://bitbucket.org/kc/pyaeso> and releases are made via the Python Package Index at <http://pypi.python.org/pypi/pyaeso>. Online documentation is available at <http://packages.python.org/pyaeso>.
A basic knowledge of the Python programming language is required to use this library. Python is an easy to learn, powerful language. An excellent introductory tutorial is available at <http://docs.python.org/tutorial/>.
Extract the archive, enter the recovered directory and type:
python setup.py install
Some code samples that use pyaeso are availble in the examples directory. One sample is listed here:
>>> # Standard Library imports >>> import sys >>> import datetime >>> try: ... # Python 3.x style ... from io import BytesIO ... except ImportError: ... # Python 2.x ... from StringIO import StringIO as BytesIO ... >>> # 3rd Party Module imports >>> import aeso >>> from aeso import equilibrium >>> >>> # Program >>> end_date = datetime.date.today() >>> start_date = end_dt - datetime.timedelta(1) >>> f = BytesIO() >>> try: ... equilibrium.dump_equilibrium(f, start_dt, end_dt) ... ofs = f.seek(0) ... data = list(equilibrium.parse_equilibrium_file(f)) ... finally: ... f.close() ... >>> for d in data: ... print d.t.astimezone(aeso.AB_TZ), '$' + str(d.price), str(d.demand) + 'MW' ...
- Python <= 2.3 - Fails because pyaeso uses several standard library modules that were introduced in Python 2.4.
pyaeso 0.7 (2011-12-26)
- Support for Python 2.7, 3.0, 3.1, and 3.2 added and tested.
- Added timeout parameters to most urlopen and dump functions.
- Simplified test infrastructure.
- Fixed date handling in ATC to match AESO’s new format.
- Removed all ATC functions from pyaeso.ets module. These functions have been marked as deprecated since 0.5 and have been replaced by the aeso.atc module.
- Updated aeso.csd parser to convert total net generation values of ‘-’ to ‘None’ rather than throwing a ValueError.
- Updated examples to use aeso package.
