DC microgrid controller needs to carryout numerous control action including voltage and current regulation as well as energy storage synchronization . This review paper is inspired by the recent increase in the deployment of DC microgrid systems for real-world residential and industrial application.
The energy management system (EMS) in this paper is designed specifically for DC power storage in a microgrid with multiple different energy storage units, the charging and discharging of lithium-ion batteries and SCs are controlled by bidirectional DC–DC converters and the battery is based on two different droop coefficient algorithms.
This paper introduces an energy management strategy for a DC microgrid. The strategy involves a photovoltaic module as the main source, an energy storage system (battery), and a critical DC load. Efficient management of these microgrids and their seamless integration within smart and energy efficient buildings are required.
This review paper is inspired by the recent increase in the deployment of DC microgrid systems for real-world residential and industrial application.
