Package: volttron-openadr-ven
OpenADRVen AgentOpenADR (Automated Demand Response) is a standard for alerting and responding to the need to adjust electric power consumption in response to fluctuations in grid demand.PrerequisitesPython 3.8InstallationCreate and activate a virtual environment.python-mvenvenvsourceenv/bin/activateInstall volttron and start the platform.pipinstallvolttron# Start platform with output going to volttron.logvolttron-vv-lvolttron.log&Install and start the Volttron OpenADRVen Agent.vctlinstallvolttron-openadr-ven--agent-config<pathtoagentconfig>\--vip-identityopenadr.ven\--startView the status of the installed agentvctlstatusObserve DataThe OpenADR publishes events on the message bus. To see these events in the Volttron log file, install aListener Agent:vctl install volttron-listener --startOnce installed, you should see the data being published by viewing the Volttron logs file that was created in step 2.To watch the logs, open a separate terminal and run the following command:tail -f <path to folder containing volttron.log>/volttron.logAgent ConfigurationThe required parameters for this agent are "ven_name" and "vtn_url". Below is an example of a correct configuration with optional parameters added.{"ven_name":"PNNLVEN","vtn_url":"https://eiss2demo.ipkeys.com/oadr2/OpenADR2/Simple/2.0b","cert_path":"~/.ssh/secret/TEST_RSA_VEN_210923215148_cert.pem","key_path":"~/.ssh/secret/TEST_RSA_VEN_210923215148_privkey.pem","debug":true,"disable_signature":true}Save this configuration in a JSON file in your preferred location. An example of such a configuration is saved in the
root of this repository; the file is namedconfig_example1.jsonTestingIf you don't have a dedicated VTN to test the VolttronOpenADR against, you can setup a local VTN instead. This VTN will be hosted at localhost on port 8080 (i.e. 127.0.0.1:8080). This VTN will accept registrations from a VEN named 'ven123', requests all reports that the VEN offers, and create an Event for the VEN. After setting up a local VTN, configure an VolttronOpenADRVen Agent against that local VTN and then install the agent on your VOLTTRON instance. Ensure that the VOLTTRON instance is running on the same host that the VTN is running on.To setup a local VTN, we have provided a script and a custom agent configuration for convenience. Follow the steps below to setup a local VTN and corresponding Volttron OpenADRVen Agent:Setup VTNSetup a dedicated environment for the VTN.Clone this repo.Create a dedicated virtual environment for the VTN:python-mvenvenvsourceenv/bin/activateInstallopenleadr:pipinstallopenleadrAt the top level of this repo, run the VTN server in the foreground so that we can observe logs:pythonutils/vtn.pyThis VTN uses port 8080 by default. If you want to use a custom port, set the environment variable "VTN_PORT" to your desired port and start the VTN. For example:VTN_PORT=8081pythonutils/vtn.pyAfter you start the VTN, you should see the following logs:Ifyouprovidea'ven_lookup'toyourOpenADRServer()init,OpenLEADRcanautomaticallyissueReregistrationRequestsforVENsthatdon'texistinyoursystem.
