2020.24.0

The OpenEMS Conference 2020 was held this week. The videos will soon be available on https://openems.io/

Highlights

• Implement Asymmetric Active Power Voltage Characteristic and Symmetric Reactive Power Voltage Characteristic Controllers (#1258) Thanks @huseyinsaht and @venu-sagar
  • These Controllers actively help to support grid stability with an energy storage system. Tested in research projects like EASY-RES and actual customer projects with European grid operators
  • This pull-request also adds a generic PolyLine implementation
• Improve GoodWe ET + BT battery inverters implementation (#1201) Thanks @venu-sagar
  • This pull-request brings full control for the GoodWe ET and BT battery inverters
  • ATTENTION: Renaming bundle to GoodWe instead of GoodWe.ET; this will break existing configurations!
• Implement Controller for a SG-Ready Heat Pump (#1289) Thanks @sebastianasen
  • Controls a heat pump that implements the SG-Ready standard via two Relay contacts, depending on surplus power and battery state-of-charge.
• Improve Debug-Log-Controller 47cbae5
  • This adds useful features to the Debug-Log-Controller for developers and technical users
  • add configuration options:
    • additionalChannels: add additional Channels to the log
    • ignoreComponents: ignore the output of certain Components
• Implement Virtual Subtract Meter (#1290)
  • _This adds a virtual meter. Example use-case: create a virtual Grid-Meter from Production-Meter, Consumption-Meter and Energy Storage System (ESS):
    • by definition Consumption is defined as `Consumption = ESS + Grid + Production (AC)
    • or: `Grid = Consumption - ESS - Production (AC)
    • this can be achieved by configuring the Consumption-Meter as Minuend and Production-Meter and ESS as Subtrahends.
• Add support for Socomec e27 e28 meters (#1303) Thanks @greemo
• Further development and rework of the EVCS (Electric Vehicle Charging Station) components (#1263) Thanks @sebastianasen

Bug Fixes and Other Changes

• Socomec: fix detection of threephase meter db61532
• OsgiValidateWorker: Delay announcement of defective Components; this hides non-critical errors due to time delay on activate 32ca90a
• Core.Host: persist configuration of network and USB devices in EdgeConfig (#1292)
• Avoid resolve errors in EdgeApp and BackendApp.bndrun (#1297), Fix #1296
  • Let Travis fail if resolving changes the existing bndrun files
  • Always update EdgeApp + BackendApp bndrun files in prepare-commit script
  • Fix existing resolve error in BackendApp.bndrun
• FENECON DESS: fix calculation of State-of-Charge value c3cb0c1
• PredictiveDelayCharge-Controller: fix class variables bug (#1299)
• Improve WAGO Fieldbus implementation (#1301)
• DebugLog-Controller: sort Components also by Component-ID number
  • Before it would sort: _sum[foo:bar|EssSoc:50 %] dummy1[def:uvw] dummy10[jkl:opq] dummy2[ghi:rst]
  • Now it sorts: _sum[foo:bar|EssSoc:50 %] dummy1[def:uvw] dummy2[ghi:rst] dummy10[jkl:opq]
• Add invert configuration for Schneider smartlink (#1302) Thanks @greemo
• Fix typos #1288 #1287 #1307 #1308 Thanks @luzpaz
