A Multilevel Approach for the Optimal Control of Energy Systems Distributed over the Territory

An approach to deal with distributed power flows and micro grids with renewable and storage is here proposed. Specifically, a multilevel architecture is defined for different main purposes: to reduce the computational complexity at a centralized approach, to deal with different micro grids, different decision makers and multiple objectives. The micro grids decision problem is LQ (or LQ tracking) and its solution can be directly inserted as a constraint in the decision problem of an upper level. In this work, two decision levels are described as well as the possible extension to case studies with several decision levels. Moreover, a solution approach based on Model Predictive Control is defined and applied. The architecture is applied to a specific case study (Savona, Italy).
