Understanding the DERMS Summary Tab
The DERMS Summary tab displays high level information related to the system, weather zones, and large scale utility DERs. All of the information is based on real-time conditions and current output of all resources. It is meant to provide as a quick reference overview broken down by technology types that are currently having an impact on the system. This tab contains three tables that display the following information:
• The System Summary table contains the current output (MW and MVAr) for each technology type of DER, the current total DER output, the total generation capacity (MVA), and the current total load for the entire distribution system.
• The Weather Zone Summary table displays the current output (kW and kVAr) of each weather affected DER technology type for each weather zone. It also has a column for the total output and generation capacity (kVA) for the weather zone that sums the various technology types present.
• The Utility DER Summary table displays the current output (kW and kVAr) of the individual DER units that do not belong to a weather zone (for example, utility scale gas generators or batteries). This table will also show the generation capacity (kVA) of the unit.
System Summary Table
• Wind (MW/MVAr): The total wind generation on the system in MW and MVAr.
• PV (MW/MVAr): The total photovoltaic (PV) generation on the system in MW and MVAr.
• Fuel (MW/MVAr): The total fuel generation on the system in MW and MVAr.
• Battery (MW/MVAr): The total battery generation on the system in MW and MVAr.
• Total Generation (MW/MVAr): The total generation of all DER technology types summed together in MW and MVAr for the system.
• Generation Capacity (MVA): The total generation capacity of all DER technology types summed together in MVA for the system.
• Total Load (MW/MVAr): The total demand on the system from loads.
Weather Zone Summary Table
• Weather Zone: The name of the weather zone.
• Wind (kW/kVAr): The total wind generation in kW and kVAr for the weather zone.
• PV (kW/kVAr): The total Photovoltaic (PV) generation in kW and kVAr for the weather zone.
• Fuel (kW/kVAr): The total fuel generation in kW and kVAr for the weather zone.
• Battery (kW/kVAr): The total battery generation in kW and kVAr for the weather zone.
• Total Generation (kW/kVAr): The total generation of DER technology types summed together in kW and kVAr for the weather zone.
• Generation Capacity (MVA): The total generation capacity of all DER technology types summed together in MVA for the weather zone.
Utility DER Summary Table
• Resource Name: The name of the utility scale DER (for example, Large Battery or Diesel Generator).
• Substation: The substation the DER is a part of.
• Feeder: The feeder the DER is connected to.
• Power Source: The technology type associated to the unit (for example, Battery, Fuel, Hydro, and so on).
• Islandable: Indicates if the DER is capable of islanding an area of de-energized network.
• Capacity (kVA): The generation capacity of the unit in kVA.
• Output (kW/kVAr): The total output of the resource in kW and kVAr.
• Availability Price ($/MWH): The availability pricing in $/MWH for the DER unit.
• Utilization Price ($/MWH): The utilization pricing in $/MWH for the DER unit.
• Solution Time: The time the solution was last solved for this particular DER.
• NCA Status: Displays the Network Capacity Allocation Status if the DER is setup as a market participant. This will specify if the bid is accepted, denied, or curtailed.
Understanding the Weather Zone Forecasts Tab
The Weather Zone Forecasts tab allows you to see weather zone forecast information for a selected zone. With this information, you can see the forecast data (provided via an external weather service and/or the DERMS system via an adapter to NMS), and the current and forecasted output (kW, kVAr) for each DER technology type. The following information is available in the Weather Zone Forecasts tab:
• Date/Time
• Temp (F)
• Wind Speed (mph)
• Cloud Cover
• Wind Output (kW/kVAr)
• PV Output (kW/kVAr)
• Fuel Output (kW/kVAr)
• Battery Output (kW/kVAr)
• Total Generation (kW/kVAr)
The Weather Zone Forecasts tab shows information related to a specific weather zone. The forecast information displayed is for the real time output and configured forecast range. It is meant to show how DER output can change based on upcoming weather trends and forecasted conditions. For example, if the current day is supposed to transition to a cloudy day with no wind, you will be able to see how the forecasted PV and wind output begin to decrease as conditions start to change.
You can navigate to the Weather Zone Forecast tab in two ways:
• Select the Weather Zone Forecasts tab. Once the tab has opened, you need to select the zone you are interested in from the Weather Zone drop-down list.
• Select a weather zone row in the DERMS Summary tab's Weather Zone Summary table, right-click, and select View Forecast... from the context menu. The Weather Zone Forecasts tab will open with the selected zone forecast displayed.
