Mathematical modeling of microgrid optimization dispatch
Microgrids (MGs), which predominantly consist of renewable energy sources, play a significant role in achieving this objective. This paper proposes an optimized methodology for power dispatch in MGs using mixed-integer linear programming (MILP).

Microgrid grid-connected control
A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to operate in grid-connected or island mode. Our researchers evaluate in-house-developed controls and partner-developed microgrid components using software modeling and hardware-in-the-loop evaluation platforms. In contrast to conventional power systems, microgrids exhibit greater sensitivity to fluctuations in demand due to their reduced rotating inertia and predominant reliance on. In this paper, we study the modeling, the control, and the power management strategy of a grid-connected hybrid alternating/direct current (AC/DC) microgrid based on a wind turbine generation system using a doubly fed induction generator, a photovoltaic generation system, and storage elements. Microgrids represent a transformative innovation in the realm of energy management, embodying a localised grid system that can operate independently or in conjunction with the larger conventional grid.
