The motivation of this contribution is the study of the Microgrid (MG) power systems, specifically Solar-Battery-Diesel systems, which are used to support unreliable grids and provide a continuous electricity supply to the areas which have limited or even no access to the grid. The main research focus in the scientific community lies on the development of general energy management strategies (EMSs) for optimal power routing on the one hand, and providing an optimized layout-design of the MGs on the other hand. However, none of these two issues can be adequately handled in isolation from one another because they have a direct impact on each other. This work aims at tackling Model-Based Development and Design of Microgrid Power Systems by addressing the challenges of the EMSs and the layout-design based on the system model and operational requirements. For this purpose, several EMSs for scheduling generation side in the MG are developed in accordance with the operational constraints. Besides, a forecast-driven power planning approach is developed for MGs that incorporate smart shiftable loads. Furthermore, this work proposes an integrated layout-design method for optimizing the size of the microgrid considering the applied EMS. Finally, to highlight the usefulness of the developed EMSs and design approach, different examples inspired from a real case-study are presented.
