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.

50. Virtual Symmetric Add

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 - SymmetricMeter

50.1. 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.

Source Code

54. 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.

62. Simulated OpenEMS Components

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

62.1. 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
