The objective of the dispatch system will be the management of the generated and stored energy in the microgrid, ensuring that the power demand is met and optimal operation is guaranteed in terms of energy costs.
An optimal power dispatch architecture for microgrids with high penetration of renewable sources and storage devices was designed and developed as part of a multi-module Energy Management System. The system was built adapted to the common conditions of real microgrids.
The economic dispatch problem for the microgrid resources is a case of linear optimization, where the objective function and constraints depend on the prediction horizon, denoted as (N_p).
Most current literature does not investigate the interrelated influence of grid-connected microgrid economic dispatch with the resilience of the microgrid during islanded operation, instead, those operating modes are isolated and approached separately (Nelson and Johnson, 2020; Nelson et al., 2020; Jafari et al., 2018).

High penetration of Renewable Energy Resources (RESs) introduces numerous challenges into the Microgrids (MG), such as supply–demand imbalance, non-linear loads, voltage instability, etc. Hence, to address these issues, an effective control system is essential. However, challenges, such as computational intensity, the need for stability analysis, and experimental validation, remain to be addressed.
