To add single element:

var $previousElements = $();
$previousElements.add($element); 

to convert array to jQuery set of elements:

var myjQueryElementArray = [$element1, $element2, $elementN];
$(myjQueryElementArray ).map (function () {return this.toArray(); } );

to add array of elements to existing elements:

var $previousElements = $(),
     myjQueryElementArray = [$element1, $element2, $elementN];

$previousElements.add($(myjQueryElementArray).map (function () {return this.toArray(); } ));
