Cooperative Centralised and Decentralised Energy Management Systems for Active Networks

The paper proposes a hierarchical control for active networks that integrates both centralized and decentralized EMS. One day-ahead, the centralized EMS schedules the dispatching of the active resources for the next day. In real-time operation, the intraday optimization adjusts the day-ahead scheduling for technical (e.g., to relieve voltage contingencies or resolve current congestions) or economical (e.g. losses reduction) reasons with a decentralized EMS. The effectiveness of the proposed procedure has been tested on the Italian representative networks produced by the research project ATLANTIDE.
