Smart Grid (SG) integration from utility’s prospective

The listed functional systems below (and others that are not listed) need to be integrated into one SG system. Today, the functional systems provide very limited exchange of information between them, often with conflicting outcomes. Integration of these functional systems needs to be prioritised from utility prospective and written in “Utility’s SG roadmap”.
