Create A Taxonomy Group In SharePoint 2013 Using PowerShell

Steps

1. Open your SharePoint Management Shell.
2. Copy the code given below and paste it there.
3. Run the code given below to delete the SharePoint search component.

Code

$taxonomySession=Get-SPTaxonomySession -Site "https://gowtham.sharepoint.com/tutorials"
$termStore=$taxonomySession.TermStores["MMS"]
$group=$termStore.CreateGroup("MMSGroup")
$termStore.CommitAll()

Another Reusable code

function DeleteTermGroup
{
param([string]$site,[string]$termstoreName,[string]$groupName)


    $session = new-object Microsoft.SharePoint.Taxonomy.TaxonomySession($site)
    $termstore = $session.TermStores[$termstoreName]
    $group=$termStore.CreateGroup($groupName)
    $termstore.CommitAll()

    Write-Output "Create $groupName"

Delete Term Group 

function DeleteTermGroup
{param([string]$centralAdmin,[string]$termstoreName,[string]$groupName)

    $site = Get-SPSite $centralAdmin
    $session = new-object Microsoft.SharePoint.Taxonomy.TaxonomySession($site)
    $termstore = $session.TermStores[$termstoreName]
    $group=$termStore.Groups[$groupName]
    $group.TermSets|foreach{
        $_.Delete()
        $termstore.CommitAll()
    }
    $group.Delete()
    $termstore.CommitAll()

    Write-Output "Deleted $groupName"

}
