Baselines

1. Supported Devices

2. Setup

This guide will help you configure Baselining Predictions on your SmartgridOne Controller.

What you need

1. SmartgridOne Controller with internet connectivity.
2. MQTT setup. Please refer to the main MQTT page for more information:

1. Add your devices

and make sure the to the SmartgridOne Controller.

2. Add the Baseline External Signal

3. Fill in the parameters

The following parameters are customisable:

3.1 Interval Length

Type: integer

The length of the interval indicates the frequency of a new prediction point. This is generally set to 15 minutes or one hour, depending on the energy market.

3.2 Number of intervals

Type: integer

The number of intervals of the length set above. E.g. If 96 intervals of 15 minutes are created, we have predictions for the next 24 hours.

3.3 Creation format

The baselines can be created daily or at a fixed interval. These two formats have different use cases.

3.3.1 Daily

The baselines are created once a day, at a specific hour. This format allows you to select an activation hour- which is how long after creation the baseline becomes active.

E.g. A baseline is created at 9AM but only active on the next day, so the activation hour is set to 15h.

3.3.1.1 Creation Hour

Type: integer

The hour at which the baseline is created every day.

3.3.1.2 Activation Hour

Type: integer

The numer of hours after the creation hour the baseline is activated.

3.3.2 Fixed Interval

Baselines are generated at a fixed interval. Baselines are generated shortly before their activation time, and activated immediately. E.g. The baseline for the next hour is generated at :59.

3.3.2.1 Refresh Interval Type: integer

How often the baseline is regenerated. This is commonly set to 15 minutes, or one hour.

3.4 Refresh Parameter

Type: integer

A constant which specifies how long before the activation time we generate the baseline. Generally set to one or two minutes.

3.5 Follow Baselines

Type: boolean

If set to true, the devices follow the baseline that is generated. If set to false, the baselines are not followed directly. The baselines are instead used as a prediction, and followed as closely as possible. The device actions can deviate from the generated baseline, depending on uncontrollable realtime variables, such as PV prediction, uncontrollable loads and EV charging periods.

3.6 Custom Predictors (W.I.P.)

Customised prediction algorithms are used to create the baselines.

4. Enable the Baseline signal

Select all devices that you'd wish to include in MQTT Remote Control.

5. Baseline signal is added

The Baseline interface has now been activated on the SmartgridOne Controller.

We are now ready to continue. The Status column will raise any potential errors during setup.

3. Baseline Collection

Baselines can be fetched from the controller using MQTT.

The following topic is used to send a request to fetch the baselines:

standard1/rp_one_s/remoteBaselineMetrics/'controller SN'

where <Controller SN> should be replaced with the serial number of the SmartgridOne Controller that is sending the feedback.

The following message format should be used to fetch baselines:

{
    "extraTags": {
        "nodeId": <Controller SN>_site_0>
    },
    "time": <Unix Timestamp>,
    "fields": {}
}

The following topic is used to receive baseline data:

standard1/outbound/remoteBaselineMetrics/feedback/<Controller SN>

where <Controller SN> should be replaced with the serial number of the SmartgridOne Controller that is sending the feedback.

Baseline feedback is sent in the following format:

{
    "time": <Unix Timestamp>,
    "data": {
        "baseline": {
            "<Device Node ID>": [
                {
                    "endTimeUnix": "",
                    "power_W": ""
                },
            ],
        },
        "nextBaseline": {
            "<Device Node ID>": [
                {
