OpenEMS/openems: 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
