v0.19.0

Release Notes

Summary

Upgrading

• Remove _soc formula from the LogicalMeter. This feature has been moved to the BatteryPool.
• Upgrade PowerDistributingActor to handle components with the NaN metrics (#247):
  • if power bounds are NaN, then it tries to replace them with corresponding power bounds from adjacent component. If these components are also NaN, then it ignores battery.
  • if other metrics metrics are NaN then it ignores battery.
• BatteryStatus to track that a component stopped sending messages. If the battery or its adjacent inverter stopped sending messages, then the battery would be considered as not working. (#207)
• PowerDistributing to send battery status to subscribed users (#205)
• Rename microgrid.Microgrid to microgrid.ConnectionManager (#208)
• Change few resampler logs from info to debug, because they were polluting startup logs (#238)

New Features

• A new class SerializableRingbuffer is now available, extending the OrderedRingBuffer class with the ability to load & dump the data to disk.
• Add the run(*actors) function for running and synchronizing the execution of actors. This new function simplifies the way actors are managed on the client side, allowing for a cleaner and more streamlined approach. Users/apps can now run actors simply by calling run(actor1, actor2, actor3...) without the need to manually call join() and deal with linting errors.
• The datasourcing actor now automatically closes all sending channels when the input channel closes.
• BatteryPool implementation for aggregating battery-inverter metrics into higher level metrics. (#205)
• Add EV power and current streams to EVChargerPool (#201)

Bug Fixes

• The resampler now correctly produces resampling windows of exact resampling period size, which only include samples emitted during the resampling window (see #170)

Removing

• Deprecated code (#232):
  • frequenz.sdk._data_ingestion
  • frequenz.sdk._data_handling
• The pandas(-stubs) and pytz dependencies are no longer needed (#261).
