OpenEMS Edge

• FEMS Backports 2024-10-11 in #2835
  • FFR: Fast Frequency Response Controller
    • Includes:
    • 1. Fast Frequency request controller.
    • 2. Junit test cases.
    • 3. Step Response Tester changes in the simulated meter. To test FFR with the simulator meter's frequency.
  • EVCS HardyBarth: set "No meter values available" as WARN + translate
    • Changed StateChannel "METER_NOT_AVAILABE" of the HardyBarth component to level WARNING
    • Added translation files for bundle and channel
  • Batteries/Battery-Inverters: downgrade FAULT states to WARNING
    • Downgrade of all possible FAULT states to WARNING states
    • Whenever one of these states would be true, the EssGeneric will stop the battery and the inverter. If this is necessary, it must be specifically mentioned and the state should have a proper description of the fault.
  • EVCS KEBA: downgrade fault for Dip Switch 2.6, because it is now used for §14a
  • ModbusBridge: invalidate Elements on removeProtocol()
    • Invalidate (i.e. set UNDEFINED/null) Elements on removeProtocol()
    • JUnit test shows behaviour. REGISTER_100 is null after removeProtocol()
  • ModbusTcpApi: improvements
    • Fixes error taking alias (of ess) instead of Component ID. This will fix dynamically generating channel addresses.
    • ActivePowerLimit and ReactivePowerLimit result in NaN if null
    • Improved reusability of code through methods
    • Removed constant strings
  • KACO Battery Inverter: fix state transition ERROR to UNDEFINED, Frequency channel
    • Return from Error Handling to Undefined
    • Fix Hz channel name
  • Updates for FENECON Home battery
    • Adjust modbus task priority level
    • Reduce number of tasks
    • Improve stopping process
    • Improve contains task check in Modbus Bridge
  • EVCS: Hystereses with info in UI
    • Hystereses for Charging stations two config values are now shown in the ui for the evcs controller
  • Generic-ESS state machine improvement
    • The main approach is to have a statemachine which can be run all our current systems and avoiding retry start process.
    • Related to any 'Error Handling' topic should be improved or implemented seperately and required a defined generic 'Error handling' concept, which can be applied for all systems.
    • Instead of maximum start or stop time attempts, starting or stopping timeouts are taken care of and shown in UI as an failure. By doing this, its aimed to let the service or engineers to analyze the failure, and forbid to harm the battery by taking an action without know-how knowledge.
  • KACO BatteryInverter: component activate improvements + ModbusSlave
    • Removed second activate annotation
    • always set configuration in activate
  • EssPower: handle Exceptions in handleEvent()
  • Fix critical race condition in Modbus Bridge
    • Modbus-Bridge: fix criticial race condition! If ON_EXECUTE_WRITE was called before ON_BEFORE_PROCESS_IMAGE, the forever()-loop could get stuck forever, because cycleTasks was never initialized.
    • A usual cycle looks like this: ON_BEFORE_PROCESS_IMAGE -> other events -> ON_EXEUCTE_WRITE -> long wait -> ON_BEFORE_PROCESS_IMAGE -> ...
    • The time between ON_BEFORE_PROCESS_IMAGE and ON_EXEUCTE_WRITE is typically very short, especially before all Controllers are activated. This applies for the time when usually a Modbus Bridge gets activated, because this happens before all Devices and Controllers. As a result it was very unlikely, that Modbus-Bridge would receive ON_EXEUCTE_WRITE before ON_BEFORE_PROCESS_IMAGE. During activating and modifying of many components at the same time after initial setup (IBN via App Center) it seems it was much more likely for this race condition to happen.
    • In this very unlikely case, unfortunately the CycleTasksManager would get stuck, as can be seen in this log:

[modbus1] State: FINISHED -> WRITE (onExecuteWrite)
[modbus1] WRITE -> WRITE (onExecuteWrite)
[modbus1] WRITE unchanged (in onBeforeProcessImage) Delay [0] (time is invalid)
[modbus1] WRITE -> WRITE (onExecuteWrite)
[modbus1] WRITE unchanged (in onBeforeProcessImage) Delay [0] (time is invalid)
...

- This problem was solved by initializing `this.cycleTasks` from `tasksSupplier`.
- New behaviour is proven to work in `CycleTasksManagerTest.java`, `testExecuteWriteBeforeNextProcessImage()` which would fail with previous code.

• Modbus-Bridge:
  • ignore events before activate
  • renew logging to show Component-ID everywhere
• RRD4j: reduce log warnings; remove stacktrace; add channelAddress
• EnergyScheduler:
  • remove unnecessary log message
  • add log verbosity
  • cleanup config
• AbstractWorker:
  • synchronized activate/modified code
  • before calling activate twice would result in an error
  • it's still not possible to stop and restart a worker (e.g. when enabling/disabling a component that uses a worker)
• AbstractOpenemsModbusComponent:
  • combine common code of activate() and modified()
  • removeProtocol and retryModbusCommunication are handled internally by ModbusBridge
  • fix modbusReference in modified()
• Home Battery:
  • wait for activate to set hardware type default
  • ComponentManager is required; otherwise ClockProvider is null during init
• Ess.Power:
  • fix ArrayIndexOutOfBoundsException
  • fix ConcurrentModificationException when ESS are added/removed
• GoodWe Battery-Inverter: fix handleEvent called before activate. Possible NPE.
• GridOptimized charge requires a production power to run properly

  • Introduce new implementation of EnergyFlow that uses linear constraint validation and optimization

OpenEMS Backend

• FEMS Backports 2023-04 in #2623
  • Add API for Simulation-Engine Component
    • In future this should be used for scenario simulations, like what would have been the benefit of using an additional battery module

OpenEMS Edge

  • Modbus-Bridge:

    • Improve SunSpec handling for SMA PV-Inverter: certain versions do not provide END_OF_MAP but throw ILLEGAL_ADDRESS_EXCEPTION instead, causing the previous SunSpec implementation to get stuck while parsing
    • Remove unnecessary throws OpenemsException and try...catch in certain places (defineModbusProtocol(), new ModbusProtocol(), addTask(),...)
    • Optionally provide ExecuteState of an entire ModbusTask; this allows for more fine-grained evaluation of read errors

  • Switch to updated readElementOnce and/or improve brevity of CompletableFuture by using thenCompose instead of thenAccept in...

  • RRD4j: correctly postprocess queried data

    • fix querying data with different resolution than 5 Minutes

  • GoodWe

    • Optionally show values per MPPT; not per String
      • GoodWeChargerTwoStringImpl was used to represent one string from a GoodWe MPPT tracker that is responsible for two strings (GoodWe ET-Systems).
      • Possible values given by GoodWe are: MPPT Current, MPPT Power, String Current, String Voltage
      • As the current values of one string are incorrect (so far DSP-Version 12, ARM-Version 27) the power cannot be calculated as expected.
      • A new Component GoodWeChargerMpptTwoStringImpl is mirroring the GoodWe values to get the important values from: MPPT Current, MPPT Power, String Voltage (One of the two strings)
    • Update BMS Registers ChargeMaxVoltage & DischargeMinVoltage
      • Set ChargeMaxVoltage & DischargeMinVoltage
      • Handle inverter specific behaviour on empty/full battery

  • Settings|Channels: fix Persistence Priority warning
    • Warning for persistencePriority lower than backends global priority, was also shown for equals
  • Hide FooterComponent for history Children due to overlapping on different heights
    • Footercomponent overlapping content.
    • Chartjs -> responsive charts approach of setting fixed height is causing the problem, onZoom event doesnt resize the charts canvas and chart canvas gets moved down into the footer
  • Footer: fix esLint autofix mistake; hide for history detail views
  • Revert adding detail navigation to production history (this is a planned feature that was accidentially merged)
  • Fix Page count of edges pagination on initial search
