Can MMG economic dispatch optimize the energy management system of microgrids?
Building upon these foundations, this study develops a bi-level robust optimization model for MMG economic dispatch to optimize the energy management system of microgrids under the worst operating conditions, while taking into account the renewable energy uncertainty and load power fluctuation.
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.
What is a microgrid?
A microgrid is defined as a collection of interconnected loads and distributed energy sources situated within well-defined electrical boundaries, functioning as a single controllable entity about the grid (Lasseter et al., 2002).
However, in the actual operation of microgrids, various challenges are frequently encountered, including losses in transmission lines, ramp rate limitations of generators and prohibited operating zones characterized by unstable generator loads.
