Power dispatch in microgrids refers to the process of managing and distributing power generated by DERs within a microgrid. This can be a challenging task due to factors such as the intermittent nature of renewable energy sources and the need for coordination among multiple resources.
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.
Economic dispatch (ED), a fundamental issue in microgrids, has received increasing attention (An et al., 2024; Cheng et al., 2024; Joshi et al., 2023). Specifically, the ED problem in microgrids is defined as the endeavour to minimize power supply costs while ensuring the balance between power supply and demand.
Nowadays, the uncertainty of renewable energy and demand side response have become a significant issue in microgrid dispatch. To optimize the dispatching, it is usually a common way to establish the probability distribution functions of the renewables and the associated load model.
