In this paper discussed the advanced distribution management system for smart grid. With smart grids, confidence and expectations are high. To various degrees, utilities are putting smart grid initiatives in place, and many of the technologies paraded under the smart-grid banner are currently implemented in utilities. The smart-grid initiative uses these building blocks to work toward a more integrated and long-term infrastructure. If all goes as expected, smart grids will provide tremendous operational benefits to power utilities around the world because they provide a platform for enterprise-wide solutions that deliver far-reaching benefits to both utilities and their end customers.
