Implementation of PI Controller of Hybrid DC Microgrid Energy Management

This paper presents energy management in DC Microgrid. Microgrids are a growing power generating source in remote areas than the utility grid. It can be operated as a standalone & grid-connected to serve the entities. This paper concentrates on the DC Microgrid and manages the energy within the system when the grid suffers from an outage of service, and unbalanced load conditions in the grid. During grid conditions, the buses connected to it should synchronize with the grid. The voltage in the buses is same, that is verified in this paper work through controllers to the converter are also discussed. From the outcome of simulation, THD satisfies the IEC 61000-3-2 standards. The energy management in DC Microgrid is achieved by connecting hybrid source is also implemented to prevent the grid outage conditions.
