The DER Adoption Analysis application (aka. PHEV Analysis) is used to predict impacts to system resulting from the projected additions of special resource or load classes to the current Customer-Class loading.
See PHEV Analysis Setup for details on user input options for this application.
For general details on running an application, selecting and displaying output variables, see Running DEW Applications.
The Available Output Variables for the application are described in the last section of this topic.
DER Adoption Analysis enables users to simulate the impacts of various Distributed Energy Resource (or load) adoption scenarios on the system model.
User may choose multiple adoption assignment scenarios, varying by customer-class, load class, start-up patterns, etc.
The application is primarily used to model the effects that the emerging Plug-in Hybrid Electric Vehicles market introduction may have on an existing power-grid system, but can also be used to model the results of customer generation (i.e. negative loading) via solar, wind, storage devices, etc.
Based on user input, the application randomly assigns targeted load adoptions to candidate Customer-Classes over a defined project period.
System impacts are then analyzed in terms of induced component overloads and low-voltage conditions, generating a detailed report comparing states before and after adopted load implementation.
Running the application initially opens the setup menu (with setup defined
from previous run's settings when applicable), allowing user to define
the adoption scenarios to be considered for the current run. (See PHEV Analysis Setup for details)
The application incorporates standard charge profiles (defined by EPRI)
into the defining characteristics for various load classes of Plug-in
Hybrid Electric Vehicles. See PHEV Charge Profiles
for more information.
Once the user has completed defining the desired setup (i.e. adoption
assignments, projection period, etc), the application run generates before
and after output variables, as well as the detailed report (when applicable).
For this application, the PHEV Analysis Report is generally the best way
to review the output for a system run, as it conveniently displays all
details of the analysis setup and results, providing intermediate data
not available from the before and after outputs.
If the user prefers to review a run's output graphically on the drawing, i.e. for a picked component data or characteristic plots (see PHEV Percent Loading sample plot), the following application variables are available.
For general details on running an application, selecting and displaying output variables, see Running DEW Applications. The output variables available for display from the application are described in the following table.
