Advanced functions for DSOs control center

The development of the Dispersed Generation (DG) in Distribution Networks (DN) requires new planning and operational tools. The Distribution Company takes the role of the Distribution System Operator (DSO) that has to manage the network from many points of view; in particular, DSOs need advanced tools to manage DNs with respect to security, reliability and quality constraints, and to improve the Hosting Capacity (HC) of the system. To fulfill these goals, it is necessary to estimate the state of the network in different operating conditions, also considering the DG. Moreover, the new standard framework requires that the DG provides, among others, reactive support. The paper presents the preliminary results of the INGRID 2 project, which is the product of the collaboration among Politecnico di Milano, SIEMENS SpA and Universita degli Studi di Milano and represents a tool developed to answer the above mention needs of the DSO.
