A Microgrid is a part of an electrical distribution system that can operate autonomously either in parallel with the main grid or isolated from the main grid. The operational flexibility of a microgrid reduces the vulnerability of the power system and also helps to avoid costly blackouts. In Colombia there is great potential for the creation of microgrids that use power generated by small hydropower plants, which are considered as a low environmental impact technology. small hydropower plants are currently unable to operate in isolation as they do not have the mechanisms required to maintain stable frequency and voltage levels after disconnection from the interconnected system. In this paper, we propose the idea of planning a Microgrid using real data from a distribution system that has an small hydropower plant installed in order to evaluate its transitory behaviour when faced with disturbances. Different control strategies are implemented, with the aim of determining which system shows the best performance.
