10. Core services for OpenEMS Edge

10.1. ComponentManager

A service that provides easy access to OpenEMS-Components and Channels. It also provides some sub-services:

DefaultConfigurationWorker

Applies a default configuration, i.e. activates certain OpenEMS Components that are to be enabled by default on deployment, like Modbus-TCP-Slave Api and JSON/REST Api.

OsgiValidateWorker

Checks if configured Components are actually enabled.

OutOfMemoryHeapDumpWorker

Checks for heap-dump files which get created if OpenEMS Edge crashed because of an OutOfMemory-Error in a previous run.

10.2. Cycle

Provides the core runtime Cycle of OpenEMS Edge

10.3. Host

A service that provides host and operating system specific commands like configuration of TCP/IP network.

10.4. Meta

A service that provides 'OpenemsConstants' as Channels so that they are available via Apis; example: _meta/Version for the current version of OpenEMS Edge.

10.5. Sum

A service that holds summed up information on the power and energy flows, like aggregated production, consumption and energy storage charge/discharge.

10.6. AppManager

A service for managing Apps. It creates, deletes and updates Components, Network configuration and the execute order of the Components in the scheduler.

10.7. App

The predefined Apps for the AppManager.

11. Edge-2-Edge

Enables Edge-to-Edge connection of devices from a slave OpenEMS Edge via Modbus. This requires Controller Api Modbus/TCP Read-Write to be active on the slave system, e.g. via the FEMS App Modbus/TCP Schreibzugriff for a FENECON Energy Storage System.

11.1. Implementations:

  • Edge2Edge.Ess

11.2. Example application

  • Setup a 'Slave' OpenEMS Edge instance, that controls one or more energy storage systems

    • Component-ID of the energy storage system or the ESS-Cluster is ess0

    • Activate Controller Api Modbus/TCP Read-Write and add ess0 to the configured component_ids

At this point you can open OpenEMS UI and check the system profile under settings. Click on the ctrlApiModbusTcp0 component and download the generated Modbus/TCP register table. You should find ess0 listed there. An example Excel file can be found here: https://github.com/OpenEMS/openems/tree/develop/io.openems.edge.controller.api.modbus/doc
This is the setup you will find after purchasing a "FEMS App Modbus/TCP Schreibzugriff" for a FENECON Energy Storage System

  • Setup a 'Master' OpenEMS Edge instance.

    • Configure Bridge Modbus/TCP:

      • id: modbus0

      • ip: IP-Address of the Slave instance

    • Configure Edge-2-Edge ESS:

      • id: ess0

      • remoteAccessMode: AccessMode.READ_WRITE (for default Read-Only access this would be AccessMode.READ_ONLY)

      • remoteComponentId: ess0

      • modbus_id: modbus0

    • Now you are able to access the remote energy storage system as if it was connected locally, e.g. configure a Controller Ess Fix Active Power on ess0 to set a fixed charge or discharge command.

20.2. Additional application notes

The charging station comes with up to four physical connectors. This implementation is designed in a way, that each connector is represented by an individual OpenEMS Component. So if you have a Alpitronic with two connectors, please configure two "EVCS Alpitronic Hypercharger" with the connector configuration property set to SLOT_0 and SLOT_1 respectively.

Supported Firmware versions: 1.7.2 and higher.

Source Code

21. EVCS Cluster

Distributes the charging power (Depending on the implementation) to the prioritized charging stations. The implementations calculate the maximum power that can be used by all charging stations.

Possible Cluster implementations:

Cluster for peak shaving
The peak shaving cluster is calculating the power depending on the grid power that can be used per phase, the maximum allowed storage power and the current values of grid, storage and EVCS consumption.

Cluster for self consumption
The self consumption cluster is calculating the power depending on the excess power.

22. EVCS Core

22.1. Core

Core services for electric vehicle charging.

22.2. Implementing an Electric Vehicle Charging Station

These are a couple of steps that should be helpful in your implementation of a new evcs component. Note that some parts may still be missing.

  1. Gather all the important information about your Electric Vehicle Charging Station (EVCS)

    1. Communication Protocol

    2. Possible Read/Write values (Important for used Natures and their values)

    3. IP address, URL, Modbus Unit ID, or any other relevant parameters required for the communication

  2. Select Natures depending on the Read/Write values provided by the evcs (In many cases more than one)

    • Evcs (Basic reading functionality)

    • ManagedEvcs (Additional Channels and functions for writing charge power limits)

    • SocEvcs (Additional Channels for the State of Charge information)

  3. Use already existing Bridge (e.g. Hypercharger using AbstractOpenemsModbusComponent) or create a new bridge (Not every protocol is/can be generalized in a separate bundle)

    • Note that AbstractManagedEvcsComponent cannot be used if the component is a modbus component (Some functions must be called manually)

  4. Create Component based on the evcs related natures. Example HyperchargerImpl:

    @Designate(ocd = Config.class, factory = true)
@Component(//
		name = "Evcs.AlpitronicHypercharger", //
		immediate = true, //
		configurationPolicy = ConfigurationPolicy.REQUIRE //
)
@EventTopics({ //
		EdgeEventConstants.TOPIC_CYCLE_BEFORE_PROCESS_IMAGE, //
		EdgeEventConstants.TOPIC_CYCLE_EXECUTE_WRITE //
})
public class HyperchargerImpl extends AbstractOpenemsModbusComponent
		implements Evcs, ManagedEvcs, OpenemsComponent, ModbusComponent, EventHandler, Hypercharger, TimedataProvider {

    • @Designate: Standard

    • @Component: Standard

    • @EventTopics: Handle this events in the handleEvent method

    • AbstractOpenemsModbusComponent: Ease the communication with a modbus device

    • Evcs: See above

    • ManagedEvcs: See above

    • OpenemsComponent: Identifies an OpenemsComponent

    • ModbusComponent: Specific for modbus component

    • EventHandler: Used to act in a specific Event in an Openems Cycle

    • Hypercharger: Individual "Nature" for additional Channels besides the evcs natures

    • TimedataProvider: Needed for this evcs to calculate the total energy charged

  5. Create Properties needed. Most important for components not using AbstractManagedEvcsComponent:

    /**
* Handles charge states.
*/
private final ChargeStateHandler chargeStateHandler = new ChargeStateHandler(this);

/**
* Processes the controller's writes to this evcs component.
*/
private final WriteHandler writeHandler = new WriteHandler(this);

  6. Constructor using ChannelIds of implementing Natures:

    public HyperchargerImpl() {
		super(//
				OpenemsComponent.ChannelId.values(), //
				ModbusComponent.ChannelId.values(), //
				Evcs.ChannelId.values(), //
				ManagedEvcs.ChannelId.values(), //
				Hypercharger.ChannelId.values());
	}

    If it is not listed here, the component is not aware of the channels in that nature.

  7. Add Activate, Deactivate & Modified

    @Activate
private void activate(ComponentContext context, Config config) throws OpenemsNamedException {
	this.config = config;
	if (super.activate(context, config.id(), config.alias(), config.enabled(), config.modbusUnitId(), this.cm,
			"Modbus", config.modbus_id())) {
		return;
	}

	/*
	 * Calculates the maximum and minimum hardware power dynamically by listening on
	 * the fixed hardware limit and the phases used for charging
	 */
	Evcs.addCalculatePowerLimitListeners(this);

	this.applyConfig(config);
}

@Modified
private void modified(ComponentContext context, Config config) throws OpenemsNamedException {
	if (super.modified(context, config.id(), config.alias(), config.enabled(), config.modbusUnitId(), this.cm,
			"Modbus", config.modbus_id())) {
		return;
	}
	this.applyConfig(config);
}

private void applyConfig(Config config) {
	this.config = config;
	this.calculateTotalEnergy = new CalculateEnergyFromPower(this, Evcs.ChannelId.ACTIVE_CONSUMPTION_ENERGY);
	this._setFixedMinimumHardwarePower(config.minHwPower());
	this._setFixedMaximumHardwarePower(config.maxHwPower());
	this._setPowerPrecision(1);
	this._setPhases(3);
}

@Override
@Deactivate
protected void deactivate() {
	super.deactivate();
}

    The Channel values set in the applyConfig are given by the config or by default.

    The Fixed Minimum/Maximum HardwarePower and the Phases Channel are used to calculate the minimum and maximum power for the user interface. (Automatically handled by calling Evcs.addCalculatePowerLimitListeners(this) or the AbstractManagedEvcsComponent)

    Maximum Charge power selected: 17000 W

    4140 W -----------------------x------------ 22080 W (charging 6 - 32 amps on 3 phases)

    Maximum Charge power selected: 1600 W

    1380 W --x--------------------------------- 7360 W (charging 6 - 32 amps on 1 phase)

  8. Modbus specific methods

    1. Reference to the modbus bridge

      @Override
@Reference(policy = ReferencePolicy.STATIC, policyOption = ReferencePolicyOption.GREEDY, cardinality = ReferenceCardinality.MANDATORY)
protected void setModbus(BridgeModbus modbus) {
	super.setModbus(modbus);
}

    2. Modbus-Register mapping

      @Override
	protected ModbusProtocol defineModbusProtocol() throws OpenemsException {
		var modbusProtocol = new ModbusProtocol(this,

				new FC3ReadRegistersTask(this.offset.apply(0), Priority.LOW,
						m(Hypercharger.ChannelId.RAW_CHARGE_POWER_SET,
								new UnsignedDoublewordElement(this.offset.apply(0)))),

				new FC16WriteRegistersTask(this.offset.apply(0),
						m(Hypercharger.ChannelId.APPLY_CHARGE_POWER_LIMIT,
								new UnsignedDoublewordElement(this.offset.apply(0))),
						m(Hypercharger.ChannelId.SETPOINT_REACTIVE_POWER,
								new UnsignedDoublewordElement(this.offset.apply(2)))),
								...

      Most mistakes: - Wrong function code, offset, or any other information provided by the Modbus protocol or manual - Wrong AbstractModbusRegisterElement for a register - Missing register (Unimportant register could be skipped with new DummyRegisterElement(xxx),) - Important tasks with Priority HIGH are blocked by other unimportant tasks with Priority HIGH - Read/Write register must be read and write in different tasks with different function codes - Scale factor overlooked. The scale factor can be easily adjusted using, for example, SCALE_FACTOR_MINUS_2

  9. Check if every Channel is set correctly

    To do this, you could add the component in the controller 'DebugDetailedLog', or download the information of a component using the 'Excel Export' feature in the system profile."

46. KACO Blueplanet Hybrid 10

46.1. Implemented Components:

  • Kaco.BlueplanetHybrid10.Core

    • This component is always required to establish the communication to the hardware device.

  • Kaco.BlueplanetHybrid10.Ess

    • This implements the Energy Storage System part (i.e. ManagedSymmetricEss) for read-only (fast internal control) or read-write (slow external control)

  • Kaco.BlueplanetHybrid10.Charger

    • This implements the DC Charger/MPP tracker for the photovoltaics system (i.e. EssDcCharger). Note that there is only one instance for both MPP trackers, because the inverter does not provide separated power values.

  • Kaco.BlueplanetHybrid10.PvInverter

    • This implements the inverter as a pure photovoltaics inverter (i.e. ManagedSymmetricPvInverter). Use this instead of Ess+Charger, if you are using the inverter purely as PV inverter without a battery.

  • Kaco.BlueplanetHybrid10.GridMeter

    • This implements the grid meter (product name "VECTIS" or "blueplanet hy-switch") connected to the inverter (i.e. ElectricityMeter)

46.2. License/Dependencies

The configuration of the Kaco.BlueplanetHybrid10.Core Component requires an identkey. This relates to the "Partner ID" that has to be acquired from Katek Memmingen GmbH. Without the identkey it is not possible to establish a communication with the hardware device.*

67. Virtual Meter

67.1. Virtual Subtract Meter

This is a virtual meter built from subtracting other meters or energy storage systems.

The logic calculates Minuend - Subtrahend1 - Subtrahend2 - …​.

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.

67.2. Virtual Add Meter

This is a virtual meter which is used to sum up the values from multiple symmetric meters. The use case for this feature is, Usually when there are multiple meters reading values from different systems, The average values from the systems make more sense for calculation and statistics.

Implemented Natures - ElectricityMeter

67.2.1. Example Configuration

  • Component-ID : meter0

  • Alias : virtualMeter

  • Meter-Type : PRODUCTION

  • Meter IDs : [meter1, meter2, meter3]

Meter IDs is a list of the meters which needs summing of the values.

The above example configuration describes, The values from the three meters configured (meter1, meter2, meter3) are summed up and average values is set to the corresponding channel address.

71. Persistence-Model Predictor

Predicts values using the 'same-as-last-day' approach.

Source Code

72. Similarday-Model Predictor

This predictor uses "Similar day technique" for prediction. This particular implementation requires mainly two inputs, which are * Num of past weeks (n) * The channels address data, which needs to predicted.

The similar-day models predicts by calculating the average of a 'n' number of previous period values.

example: the next monday predictions values is equal to average of past n = 4 monday values.

This predictor is mainly used for predicting the Consumption power and energy. And the Accuracy of the model is scientifically verified within EMSIG project.

75.2. Additional application notes

Experiences from testing this plugin with a KACO Blueplanet NX3 M2:

  • Modbus Unit-ID was 3, for both Modbus TCP and RTU. Modbus TCP also worked with Unit-ID 1, but RTU only worked with 3.

  • When using the Wlan module to connect via Modbus TCP, make sure no cable is plugged into the RJ45 socket used for Modbus RTU. If there is a cable plugged in, it will still work, but you will get a lot of connection errors.

  • Similar situation when using Modbus RTU - unplug the Wlan module. Modbus RTU still works with the Wlan module plugged in, but you will get a lot of connection errors.

  • The Wlan module that handles the Modbus TCP connection does not automatically reconnect to the configured Wlan router if it looses the connection (for example, when the router is restarted), or if the router is not reachable when the inverter starts up.

  • To reconnect, the inverter needs to restart. Since the NX3 usually shuts down over night and restarts in the morning, this is not too much of a problem.

80. Simulated OpenEMS Components

This bundle provides simulated OpenEMS Components for the Natures. They are useful for testing and demoing without real hardware.

80.1. Simulator-App

The Simulator-App is a very specific component that needs to be handled with care. It provides a full simulation environment to run an OpenEMS Edge instance in simulated realtime environment. After you ran a Simulation, you will receive the simulation result as a JSON. Also the simulation result can be viewed in OpenEMS UI.

Be aware that the SimulatorApp Component takes control over the complete OpenEMS Edge Application, i.e. if you enable it, it is going to delete all existing Component configurations!

To run a simulation:

  1. Run OpenEMS Edge using the EdgeApp.bndrun

  2. Open up Apache Felix Web Console and

    1. activate a "Controller Api REST/JSON Read-Write"

    2. activate a "Simulator App"

  3. Send a JSON-RPC Request like the following, providing full configurations for all required OpenEMS Edge Components
