(
    [Parameter(Position=1,Mandatory=$True,HelpMessage="Source UserName")]
    [string]$srcUsername,
    [Parameter(Position=2,Mandatory=$True,HelpMessage="Source Password")]
    [SecureString]$strsrcPassword,

change this line

$password = '$locpassword' | ConvertTo-SecureString -asPlainText -Force

with this:

$password = ($locpassword | ConvertTo-SecureString -asPlainText -Force)

As already mentioned by @Swonkie in the comments

There is no need to quote the parameter. Just use the parameter as provided.

param([String]$Server, [String]$locusername, [String]$locpassword)
process {
    #NOTE: no quotes on parameter $locpassword
    $secure_password = ConvertTo-SecureString -String $locpassword -AsPlainText -Force
    $credential = New-Object System.Management.Automation.PSCredential($locusername, $secure_password)
    #...other code
}

If you are still getting that error then review the value stored in $locpassword as it may have been assigned a $null value.

instead of using single quotes use double quotes , for string expansion

$password = "$locpassword" | ConvertTo-SecureString -asPlainText -Force

full code:

param([string]$Server,[string]$locusername,[string]$locpassword)

$password = "$locpassword" | ConvertTo-SecureString -asPlainText -Force 
$username = $locusername 
$cred = New-Object System.Management.Automation.PSCredential($username,$password)
