Abstract
The paper presents a novel control strategy for islanded Microgrids, based on hierarchical control and modified droop control. The robust control strategy presented allows stability voltage improvement and its transient behavior. Which subscribes to verify the performance of the proposed strategy compared with a conventional PI controller. Due to technological advances demand a huge amount of electricity, therefore Renewable Energy Resources (RES) must be near the electrical demand is huge, in addition they are implemented in rural places, where electric utility is not able to provide the service. However, the implementation of these new systems implies facing new challenges for the correct operation of Microgrid connected or islanded from the conventional system.
