Wonderful windpowerlib release v0.2.0

We are happy to present to you a new major release and therewith freshly revised windpowerlib!

The windpowerlib is a library that provides a set of functions and classes to calculate the power output of wind turbines and farms. It was founded to build a community concentrating on wind power models. Have a look at the what’s new for more information on what has changed and the examples for a quick start into the windpowerlib.

We are also happy to see that the number of users of the windpowerlib is steadily increasing. We therefore find it important to keep the API changes to a minimum from now on and announce changes well in advance. We also decided to support v0.1.3 for some more time in case you don’t want to upgrade your code to v0.2.0.

v0.3.1 – Buggy Battery

With v0.3, the API of the GenericStorage has changed. Due to the open structure of solph, the old parameter names were still accepted, but practically ignored. Therefore users may not notice that a default value is used instead of the value they wanted. Especially after an update from v0.2.x to v0.3.0, code often still runs but produces different results. With the new v0.3.1 release, an error is raised when legacy parameter names are used. We work on a structure to avoid such problems in the future. To update, just:

pip install oemof --upgrade

Comment on recently published book about oemof

Recently a book about oemof [1] has been published. As explicitly stated by the author, this book is not written by the oemof community. Generally, books about software can be a good source to give newcomers a comprehensive view of a field and show how the software can be used to approach problems in that field. In this sense, they can fulfill a purpose that goes beyond what can be reached by the documentation written by the programmers.

However, this book stays rather close to the code and much of the information provided is outdated or not presented correctly. Continue reading “Comment on recently published book about oemof”

TESPy version 0.1.0 published

With the first release of a minor version, TESPy takes an important step for future development: We have added software tests and a first benchmark case testing results of TESPy vs. results of a different commercial software. On top, the API-documentation has been revised and improved in many places. Examples for every component as well as all major modules and classes (network, network_reader, connection, bus) provide support for the users! Continue reading “TESPy version 0.1.0 published”
