Question about data displayed in the Getting Started Simulation

[JimsterCoder]

I am running the simulation, as you can see in the graphic above. I don’t understand where some of the data comes from.

Grid = meter0 = a meter measuring the power to/from the grid, this is simulating a physical meter

ess0 L: is a power reading provided by the ess, simulating data from an actually ess.

Consumption = this I don’t understand. How is this measured? The only meter we have is measuring the power to/from the grid. What device is measuring the power consumed by the house?

That is my question: What device is measuring the power consumed by the house?

(aside, I have no UI as the one in the tutorial doesn’t work and I have been unable to install node.js on my Ubuntu machine to build the UI. Any tips on this would also be appreciated)

Your help apprecieated.

Hi James,

The consumption power is not measured, but calculated from the grid power, the production power and the ess power.

Unfortunately, I can’t help you with your second question.

Best regards,

you started a websocket?
and this is not working?

perhaps i have to update the ui and upload it again. didnt test it for 3 Months.

best regards

Please take a look at this post I did about the UI.

Help with UI Section of Getting Started Tutorial

After a few issues I have gotten to Step 4. of Getting Started. When I start my UI, I see this. [image] The lower image is what it is supposed to look like. Mine is missing the Grid on the Energy Monitor and the Grid display. Also it’s in German. I would very much appreciate help getting the right display, with Grid display and how to get the display in English. Please.

Thanks

Ok, this seems too simple which is perhaps how I overlooked it.
With no ESS power, Grid = Consumption.
With ESS power supplied, which I presume IS measured and provided by the ESS…
Consumption = ESS + Grid
Consumption is calculated… not measured.

BUT, how is the CSV file data being used in the simulation after you start the Controller ESS Balancing?
I don’t see how this reflects a real system? If you push power in from the ESS, the meter reading goes down… so how is the data from the CSV file being used if it’s not the meter reading?

Ok… I guess the Simulator Grid Meter Acting not like a real meter, but using the data from the ESS and CSV, to produce the Grid result.

the ui should work again. sorry for that.

perhaps this topic helps you to understand the simulation better.

The system is not meant to make SIMULATIONS, it is just for testing propose. The simulations should be improved, but cause everybody is fokused on real Systems, there is no time. But feel free and build a good fitting simulation.

and perhaps that post helps

Simulate house energy consume

Hi Zaohon, you have to think more like an “EnergySystem” and not like a consumer. For the System is just the Grid relevant, so all the stearing/controlling is coming from that point of view. In a “normal” house you will never measure the Consumption. You always have a meter at the grid so you always just get the information of the grid (yes you can set up additional measurments, coming to this later). The simulation just simulates some parts of the energysystem BUT does not really interact l…

Exactly. You can use the Grid Meter Reacting to calculate the Grid power from consumption, production and ess power, and the NRC Meter Acting to simulate consumption from the datasource.
