Optimal Distributed-Coordinated Approach for Energy Management in Multisource Electric Power Generation Systems
Résumé
In the context of distributed power generation systems, the energy management and coordination of generators are imperative tasks to be done. Such systems, typically considered as large-scale systems, can include different dynamical and functional characteristics in both, generators and loads. In this sense, the use of distributed-coordinated control strategies, including operational constraints, becomes an interesting alternative for these applications. This chapter proposes a novel price-driven coordination technique. The approach considers that a centralized optimal control problem can be splitted into several unconstrained controlled subsystems, all coordinated by an agent which is intended for accomplishing the global performance, while assuring the system constraints. The approach is applied to a microgrid that combines different generation technologies and load profiles.
