Powershell RunAs Administrator in a SSIS Package - powershell

Question

Am trying to remote connect to a server and run a powershell script to open ports in windows firewall in a SSIS Execute Process task
Here is the Powershell code:
$computername = hostname
$script = {
$FireWallRule_1 = Get-NetFirewallRule
$par1 = #{
DisplayName = "DAC"
LocalPort = 1434
Direction="Inbound"
Protocol ="TCP"
Action = "Allow"
}
$FireWallRule_2 = Get-NetFirewallRule
$par2 = #{
DisplayName = "MSSQLSERVER"
LocalPort = 1433
Direction="Inbound"
Protocol ="TCP"
Action = "Allow"
}
$par1.Localport = 1434
$par1.DisplayName = "DAC"
if (-not $FireWallRule_1.DisplayName.Contains($par1.DisplayName)) {New-NetFirewallRule #par1}
$par2.LocalPort = 1433
$par2.DisplayName = "MSSQLSERVER"
if (-not $FireWallRule_2.DisplayName.Contains($par2.DisplayName)) {New-NetFirewallRule #par2}
}
Invoke-Command -ScriptBlock $script -ComputerName $computername
Here is the error i got:
Connecting to remote server [SERVERNAME] failed with the following error message: Access is denied. For more information, see the
aboute_Remote_Troubleshooting Helptopic.
+ CategoryInfo : OpenError: (SERVERNAME:String) [], PSRemotingTransportException
+ FullyQualifiederrorId : AccessDenied, PSSessionStateBroken
I have tried to run the PS script locally and its working, the account that run ssis is local administrator on the target server. Is it possible to RunAs Administrator in a SSIS Package?
Thanks Håkan
