 The following script is a sample of what an administrator may want to publish a specific project using  PowerShell. The script reads the list of existing projects in Project Server and publishes project based on the project name. Set the $url variable to point to the desired instance of Project Server, and then run the script.

$path = "c:\program files (x86)\Microsoft\Powershell PSI Cmdlets for Project Server 2010\ProjectPSICmdlets.dll"
$assem = [System.Reflection.Assembly]::LoadFile($path)
import-module -assembly $assem


$url = "http://pwaurl/pwa";

$dataset = New-Object System.Data.DataSet
$dataset = psi-ReadProjectList $url;
foreach ($p $projName in $projectList)
{

             if ($p.PROJ_NAME -eq "MyTestProject")
       {
             $projectUid = $p.PROJ_UID;
              "Publishing project guid = " + $projectUid
              $sessionUid = [System.Guid]::NewGuid();
              psi-CheckOutProject $url $projectUid $sessionUid "PS Check out"
              $jobUid = [System.Guid]::NewGuid()
              psi-QueuePublish $url $jobUid $projectUid $true
              $jobUid = [System.Guid]::NewGuid()
              psi-QueueCheckInProject $url $jobUid $projectUid $true $sessionUid "PS Check In"
       }
