Due to their intermittent (temporally varying) availability, On-site Resources are dealt with in a dedicated step in the scenario setup workflow.   

 

Add New

Add a New On-site Resource to your scenario.  In the box that appears, you must select an Energy Carrier corresponding to the resource and a Hub (or multiple Hubs) to which the resource should be applied.  After selecting the Energy Carrier and Hubs, you can specify the Available Resource Type:

Available Resource Area (m2): If this is selected the Hourly Resource Profile -explained below- should be in [kW/m2].

Available Peak Load (kWp): This kW-peak (kWp) refers to the nominal capacity of a technology. For example a solar PV panel of 15kWp. If this type is selected, the Hourly Resource Profile -explained below- should be in [kW/kWp].

An hourly profile with 8760 values must be provided for every resource/hub(s) combination.  These profiles can be prepared in 3 ways:

→ Generate Profile: (For now only availabe with Solar Irradiation profiles) This allows you to draw from Sympheny's databases to generate an hourly solar irradiance profile.  You must select:

  1. Location (or a representative location) for which the profile will be generated

  2. Type of profile to be generated (e.g. Façade or Roof)

  3. Slope & Orientation of the solar panels that will be used to capture the corresponding solar energy. 

After selecting the necessary parameters, a statistical summary of the profile appears below, including a note on the data source used for generating the profile.  By clicking Next, the profile is generated and you are given the possibility to add it to your scenario.

 

→ Upload Profile: A resource profile may be specified in a XLSX file and uploaded.  The profile should be specified in [kW/m2] or [kW/kWp] and for every hour of the year from the 1st of January to the 31st of December. The maximum size of the XLSX file is 2 MB. The file should consist of a single sheet, containing 2 columns, no header, and exactly 8760 rows. The 1st column should contain incrementing integers (from 1 to 8760).  The 2nd column should contain the values corresponding to the hourly energy demand in kW, as shown below.

→ Select Saved Profile: Always when uploading or generating a profile, you are given the option to Save the profile for future use.  Using Select Saved, you can load a resource profile you have saved in the past.

Tip: Downloading your irradiation profiles using external databases. Irradiation profiles can be easily generated and downloaded from webpages like PVGIS (https://re.jrc.ec.europa.eu/pvg_tools/en/#MR ), just make sure that the profile you generate has 8760 hours and that the units are specified in kWh/m2.

Add From Map (With GIS Add-on)

Automatically assign the On-site Resource profile for Solar Resources and for Wind resources from the GIS data:

→ Solar Resources:

→ Wind Resources:

By default the Available Resource Area (m2) for the Wind Resource is the area drawn for the selected Hub in the map.

AI Clustered profiles

When executing the optimization by Sympheny engine, AI clustered On-site Resource profiles by typical days are created to improve the performance of the optimization. These profiles have similar load duration curve as the original profile included by the user. The peak of each of the Energy Carrier per Hub, the peak of each of the Energy Carriers (in all Hubs) and the peak of all the Energy Carriers aggregated is also included.

Energy Demand profiles profiles are also transformed to AI Clustered profiles.
