2021.4.0

Highlights

• Implementation of Advanced Battery Protection algorithms (#1376)
  • The "Battery-Protection" implementation serves as an addition to low-level battery management systems (BMS). It allows a fine grained definition of battery protection parameters and handles logics that are shared between different BMS implementations.
• Implementation of a new Prediction architecture (#1327)
  • This new Predictor architecture uses modular Predictors, e.g. implementation of the Predictor24Hours. These Predictors can announce for which channels they allow a prediction and provide a Prediction24Hours result.
  • The entire process of getting a prediction is handled by the PredictorManager. It knows which actual Predictors to ask for their prediction, post-processes these predictions and returns them either directly in code via the Predictor::get24HoursPrediction() method or via a get24HoursPrediction JSON-RPC request to the _predictorManager component.

Bug Fixes and Other Changes

• Simulator: BatteryDummy - add missing StartStoppable channels (#1392) Thanks @clehne
• Migrate from Travis CI to GitHub Actions (#1397)
  • This fixes our continuous integration. On every push the entire source code gets built automatically and checked for JUnit test errors.
  • On push to develop the OpenEMS docs and Javadoc get rebuilt: https://openems.github.io/openems.io/openems/latest/introduction.html
• Improve OpenEMS documentation (#1399)
  • Integrate some documentation that was created within the EASY-RES research project: https://openems.github.io/openems.io/openems/latest/randd.html#_easy_res
