Development of innovative systems for operation and control of electric power distribution networks: Management and optimal use of distributed generation and of nenewable energy resources

The integration of distributed energy resources for the production of electrical energy is related to the evolution of future power distribution networks in order to achieve: flexibility (meeting final user's requirements); accessibility (allowing access to local generation and particularly to renewables); reliability (ensuring the highest possible security and power quality levels); economy (allowing an adequate management of energy in an efficient and competitive way).In this framework, the paper presents some results of a joint research project involving five Italian universities. The focus is on the proposition and development of the main functionalities implemented into a centralized Distribution Management System (DMS) for the operation and control of the energy resources connected to distribution networks (generation, storage and loads) and of the network itself (automation systems, protection, etc.). Architecture, hierarchical structure and relevant functions for the control, operation and management of the active distribution network, are illustrated.
