In this article, you will learn how to use the Demand Load Widget.
This widget allows you to see your power excess in your Dashboards, with all the benefits that the Dashboards have, such as customisation and shareability.
You will find the following information:
Demand load preset allows users to see the demanded power for a device with Active Energy data, and compare it to the contracted load over a given period.
This is done based on the Excess Power structure applied to the device studied.
Right now, there are four available and current excess load strategies in DEXMA. For now, three of them are available in the Demand Load widget:
Circular 3/2020 Fórmula Simple
Circular 3/2020 Fórmula Compleja
Peak hours power - Portugal
You can learn more about EXcess power concept and other price's concepts in this article.
Before you create a Demand Load widget you need to make sure that you have:
- A device with quarter-hourly or hourly data, depending on the Excess power strategy that you are choosing.
- A price with one of the Excess power strategies mentioned above. You can learn about the Price concepts and their configuration in this article.
- A Supply (and valid contract) with the mentioned price assigned to the mentioned device.
1. Go to the Dashboards section
2. Create a new Dashboard with the + sign or edit an existing one
3. Add a new Demand Load widget
4. Choose the Device and period that you want to see, and press Save.
The resolution is applied automatically depending on the Excess power strategy configured for the price linked to the device.
For now, the options for the visible periods are limited.
The widget plots the demand load in a coloured bar chart following the same pattern:
Green: There is no excess
Red: There is excess demand
The contracted load is shown as a blue line.
The resolution, as said before, depends on the excess strategy associated. That is why, if there is a contract change in the device that you select, the chart will adapt the resolution to each of the strategies in these two contracts
The chart will display the data in different resolutions as an exception to usual behaviour in the platform. In the following example, there is a contract change happening in the 17/04/2023:
The first contract is using Circ 3/2020 Complex formula strategy, with quarter-hourly data, and the second contract uses Circ 3/2020 simple formula strategy, with hourly data. The readings are correct, considering that each contract has its own resolution.
If the excess power cannot be calculated for a given timestamp (ie Portugal Peak hours outside of P1), the demand load will be shown in grey, and the contracted load will not be shown:
*For the Peak hours (Portugal) strategy, only the excess power for period P1 is calculated, so the rest of the periods appear in gray. The platform does not have excess power data for P2-P4.
You can also see an error message in the following situations:
No Excess demand strategy configured for in the price assigned to the selected device:
You should configure a price that has an excess demand strategy.
No valid contracts configured for the selected device:
You should configure a valid contract (with power excess)for that device.
Excess power strategy is not enabled:
If this appears, it means that the load excess strategy configured in the price assigned to this device is not one of the 3 mentioned above as available.
- Remember that you also have the same options that with other Dashboard's widgets: change the title and the layout in the Dashboard easily!
- We are working on a table to complement this widget to see more detailed information about your power excess.
- You might remember our former Demand load tool, the Demand Load app. This widget and the upcoming updates are the improved version of it.
