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 (Change PowerDistributor to ignore components with 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. (Change battery status when component stopped sending data #207)
• PowerDistributing to send battery status to subscribed users (Add BatteryPool implementation for aggregating battery-inverter data #205)
• Rename microgrid.Microgrid to microgrid.ConnectionManager (Rename microgrid.Microgrid to microgrid.ConnectionManager and its Insecure-companion #208)
• Change few resampler logs from info to debug, because they were polluting startup logs (Change few resampler logs from info to debug #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. (Add BatteryPool implementation for aggregating battery-inverter data #205)
• Add EV power and current streams to EVChargerPool (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 Resampled timestamps don't have constant interval #170)

Removing

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