2025.1.0

Release Highlights

• Implement Long Short-Term Memory (LSTM) predictor by awesome @Bishalghimire1997 in #2721

  • The Long Short-Term Memory (LSTM) model is a type of recurrent neural network (RNN) that is particularly well-suited for time series prediction tasks, including consumption and production power predictions, due to its ability to capture dependencies and patterns over time. https://en.wikipedia.org/wiki/Long_short-term_memory[More details on LSTM]
  • This application is used for predicting consumption power values.

OpenEMS Edge

• FEMS Backports 2024-12-10 in #2916
  • ENTSO-E: added preferred resolution config
  • ModbusTcpApi: fix updating ModbusRecordTable
    • Clears ModbusList on initializing => components, that are removed in the modbus component_ids cant be accessed by qmodmaster anymore.
    • Fixed ModbusComponents getting actually removed out of array => resulted in write commands not being executed after esscluster change
    • High Prio because this bug could lead to serious problems on our systems, especially on Industrial systems.

    • Added resolution property to be able to be configurable through APP.
    • Fixed the ENTSO-E Bug where prices are mismatched by 15 mins.
  • Prediction ValueRange: fix possible NPE if value is null
    • In my refactoring of the Prediction class I missed handling of a situation where a NullPointerException could happen.
    • This leads to the problem that - if no local historic values are existing, e.g. after system outage or at IBN, the prediction fails with a NullPointerException.
  • Time-of-Use-Tariff: apply ESS_MAX_SOC in Run-State
    • Unfortunately this had been lost during splitting of Optimizer and ToU-Controller
    • Also increasing the value to 94 % to take into account larger storage systems
