2020.4.0

Common

• Add information about R&D project MEMAP #1044 https://openems.github.io/openems.io/openems/latest/randd.html#_memap
• Fix readme for REST-Api Controller 71a05b9 https://openems.github.io/openems.io/openems/latest/edge/controller.html#_rest_api_controller
• Update UI and Java dependencies 9c283ab

Edge

• Improvements to Simulation capabilities
  • Improve CSV datasource 5443338
    • Move existing CSV Datasource with predefined CSV files to "Simulator DataSource: CSV Predefined"
    • Add new "Simulator.Datasource.CSV.Direct". It allows configuring the CSV content directly in Apache Felix
    • Allow CSV without titles
  • Fix NRC (non-regulated-consumption) meter and Reacting GridMeter: this allows simulating Loads using a simulated NRC Meter 9de12ea
  • Full documentation on this feature is still missing, but it alread proved to be helpful in a university lecture about energy flows. To create a simple, static enery flow with grid, pv production, storage and loads that can be visualized in OpenEMS UI, configure:
    • to simulate a consumption of 5000 W, resulting in buy-from-grid 5000 W
      • Simulator DataSource: CSV Direct
        • Component-ID: "datasource1"
        • Source: "5000"
      • Simulator NRCMeter Acting
        • Component-ID: "meter1"
        • Datasource-ID: "datasource1"
    • Simulator GridMeter Reacting
      • Component-ID: "meter0"
    • to add a production of 10000 W to the simulation, resulting in sell-to-grid 5000 W
      • Simulator DataSource: CSV Direct
        • Component-ID: "datasource2"
        • Source: "10000"
      • Simulator ProductionMeter Acting
        • Component-ID: "meter2"
        • Datasource-ID: "datasource2"
    • to add a battery in self-consumption optimization mode to the simulation, resulting in 0 W grid exchange and battery charging of 5000 W
      • Simulator EssSymmetricReacting
        • Component-ID: "ess0"
      • Controller Balancing Symmetric
        • Component-ID: "ctrlBalancing0"
        • Ess-ID: "ess0"
        • Meter-ID: "meter0"
• Fix bug in RRD4j Timedata 586460c; thanks to @ahummelsberger
• Split API Controllers in Read-Only and Read-Write variants: This allows deploying an energy management system by default with a read-only apis
  • JSON/REST-Api 05e26dc
  • Modbus/TCP-Slave Api 2faa57e
• ComponentManager: fix OsgiValidateWorker for defective components that get removed. Before OsgiValidateWorker would throw an exception, when a component configuration was removed, but the Component-ID was still considered 'defective' b5759b2
• Add UUID-helper: add helper function to provide a 'Nil' UUID. See https://en.wikipedia.org/wiki/Universally_unique_identifier#Nil_UUID ca0150a

UI

• UI: Fix refresh config from Edge: do not refresh simultaneously ea86ef6 7dbe4c4
