Integrazione delle Fonti Rinnovabili nelle SMART-GRID

Energy market liberalization processes and incentive programs by various National governmwnts are driving an increasing diffusion of a wide variety of Distributed Generation (DG) powe plants, causing huge changes and challenges in Electrical Power Systems (EPS). in fact, while in the past the power generation was mainly concentrated in a small number of large power plants directly connected to the high voltage Transmission Networks (TNs), DG units can be connected directly to Disribution Networks (DNs), causing both DNs planning and management issues. Thus, innovative planning and management approaches of these new active networks are necessary to ensure the best integration of Distributed Energy Resources (DERs) within EPSs as well as TNs and DNs optimal use. The thesis work addresses these aspects by investigating DERs integration issues and their impact on voltage profiles within DNs. The work proposes a technique for DERs decentralized control at the Point of Commom Coupling (PCC) with the DN, designed to contain voltage variations within regulatory limits and to maximize active power delivery to the grid...
