In Ref. [89], a centralized MPC was applied to coordinate the power flow among a microgrid network. The predictive model is constrained with an upper and a lower limits. The cost function has two parts, both related to the energy sold or purchased, the first one is about adjacent microgrids while the second one about the utility grid.
Microgrids (MGs) can be either small‐scale power grids with few modules or medium‐scale power grids with a large number of modules and units. MG dynamic modeling contains two main steps.
