General Description

The Microgrid Power System, "AEL-MGP", has been designed for the theoretical-practical training on microgrid power systems.

Thissystem allows studying the architecture, management and the main control maneuvers carried out in a hybrid context based on renewableenergies. This is power system which stands for the set of renewable resources (photovoltaic, wind and hydroelectric) integrated into anisolated grid for power production. Moreover, the design of this system has been done with actual scaled industrial elements with the aimof gaining the maximum experience with the management of a microgrid.

The "AEL-MGP" Microgrid Power System is constituted by a set of applicationsrecommended to study the different scenarios that can occur in a micro grid. Dueto the diversity of micro grids Edibon recommends a set of applications with thepurpose of the user selecting those based on the situations he wants to study.

Therecommended applications are as follows: Conventional Energy Power Plants,Hydroelectric Power Power Plants, Wind Power Plants, Energy Storage Power Plantswith Batteries and Energy Storage Power Plants with Flywheel.
