2021.18.0

Highlights/New implementations

• Time-of-use-Tariff Discharge Controller
  • Schedules the discharging of an AC or DC energy storage system in the night based on time-of-use prices, predicted production and consumption. Thanks @venu-sagar
• ESS Cycle Controller: executes charge/discharge cycles on an ESS. Thanks @huseyinsaht
• Generic Off-Grid ESS Implementation
  • Similar to the existing Generic-ESS, this Off-Grid variant takes any off-gridable battery inverter (like Sinexcel), any battery and an external device that manages grid-switching and off-grid detection to seamlessly transfer between public- and micro-grid. Thanks @huseyinsaht

Bug Fixes and Other Changes

these improvements are mainly backports from FENECON Energy Management System (FEMS) #1637

• Generic/Build/...

  • Extract wrapper for OK HTTP library so that it can be used easier by other Components
  • Improve Modbus Communication errorhandling
    • In case of a modbus communication error there used to be a Fault state on the Modbus Bridge. This improvement moves the Fault state to the actual Modbus device instead.
    • New Fault state ModbusCommunicationFailed inside the ModbusComponent Nature
    • Properly implement ModbusComponent Nature in all Modbus device implementations
    • In Modbus Bridge: use global Cycle-Time
    • Add JUnit tests for Modbus-Bridge
  • Channel: refactor handling of initial value
  • Ramp-Filter: refactor
  • State-Machine: store the previous state and make it available via getPreviousState() method
  • Add feature to ignore Component Warnings and Faults in Sum
    • If you are aware that certain Components currently have an error (e.g. a Modbus-Device is not connected, KEBA charging station is turned off, etc.) you can add the Component-ID to Sum, so that it does not appear in the overall system State (_sum/State)
    • Example without ignore: [ctrlDebugLog0] _sum[State:Fault] ctrlApiRest1[State:FAULT: Unable to start REST-Api Server]
    • Example with ignore configured: [ctrlDebugLog0] _sum[State:Info|State:INFO: Component Warnings or Faults are being ignored] ctrlApiRest1[State:FAULT: Unable to start REST-Api Server]
  • TypeUtils: improve logic in case of null
  • DebugLogController: add config setting to print Component Alias and implement @Modified to apply changed configuration faster
  • Improve process of restarting defective Components via OsgiValidateWorker
  • ESS Power-Constraints: improve log messages and avoid unnecessary tests

• UI:

  • Continue refactoring of Widgets
  • many bug fixes

• Batteries/Energy Storage Systems

  • Battery-Protection: increase force-charge to 2 A by default
  • FENECON Home: add startup procedure to Battery
  • Soltaro Cluster B: Set StateChannels only if the corresponding racks are used
  • Grid-Optimized-Charge: improve logic
  • Implement Sinexcel as Battery-Inverter; drop ESS implementation
  • GoodWe:
    • implement smart-mode also for GoodWe ESS
    • implement meter that measures emergency power
  • Remove Predictive Delay Charge Controller (#1643)
    • It was replaced by the more advanced "ESS Grid Optimized Charge" Controller (io.openems.edge.controller.ess.gridoptimizedcharge).

• Input/Output

  • IO Single Channel Threshold: refactor + allow multiple outputs
  • JSON/REST-Api: improve permission handling

• Dependencies

  • Bump org.osgi.util.function from 1.1.0 to 1.2.0 in /cnf (#1642)
  • Bump org.osgi.util.promise from 1.1.1 to 1.2.0 in /cnf (#1641)
  • Bump postgresql from 42.2.23 to 42.3.0 in /cnf (#1640)
  • Bump jsoup from 1.14.2 to 1.14.3 in /cnf (#1633)
  • Bump guava from 30.1.1-jre to 31.0.1-jre in /cnf (#1630)
