The integration of renewable energy systems (RESs) in smart grids (SGs) is a challenging task, mainly due to the in- termittent and unpredictable nature of the sources, typically wind or sun. Another issue concerns the way to support the consumers’ participation in the electricity market aiming at minimizing the costs of the global energy consumption. This paper proposes an energy management system (EMS) aiming at optimizing the SG’s operation. The EMS behaves as a sort of aggregator of distributed energy resources allowing the SG to participate in the open market. By integrating demand side management (DSM) and active man-agement schemes (AMS), it allows a better exploitation of renewable energy sources and a reduction of the customers’ energy con- sumption costs with both economic and environmental benefits. It can also improve the grid resilience and flexibility through the active participation of distribution system operators (DSOs) and electricity supply/demand that, according to their preferences and costs, respond to real-time price signals using market processes.

Abstract
The integration of renewable energy systems (RESs) in smart grids (SGs) is a challenging task, mainly due to the in- termittent and unpredictable nature of the sources, typically wind or sun. Another issue concerns the way to support the consumers’ participation in the electricity market aiming at minimizing the costs of the global energy consumption. This paper proposes an energy management system (EMS) aiming at optimizing the SG’s operation. The EMS behaves as a sort of aggregator of distributed energy resources allowing the SG to participate in the open market. By integrating demand side management (DSM) and active man-agement schemes (AMS), it allows a better exploitation of renewable energy sources and a reduction of the customers’ energy con- sumption costs with both economic and environmental benefits. It can also improve the grid resilience and flexibility through the active participation of distribution system operators (DSOs) and electricity supply/demand that, according to their preferences and costs, respond to real-time price signals using market processes. The efficiency of the proposed EMS is verified on a 23-bus 11-kV distribution network.Pubblicazioni consigliate
