Advanced operation and control of active distribution networks: management and optimal use of distributed generation and of renewable Energy resources

The paper presents some of the result of a joint research project involving five Italian universities: Bologna, Cagliari, Cassino, Genova and Padova. 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 – developed at the Authors’ laboratories – for the control, operation and management of the active distribution network, are illustrated. The interface of the DMS with remote monitoring systems (of both network and dispersed resources) suitably developed by means of innovative technologies represents a key feature: in this respect the use of advanced Phasor Measurement Unit devices, developed at one of the laboratories involved in the research project, is illustrated in the paper along with the main features of the developed units. As the development of the DMS functions is related to the regulatory scenarios and as, at the same time, the evolution of future distribution networks is influenced – for a fixed scenario –by the DMS itself, the paper also addresses the issue of the definition of a framework of regulatory scenarios in which the DMS, its control and operation functions are expected to be tested and assessed.
