Autonomous DC-Bus Voltage Regulation in DC Microgrid Using Distributed Energy Storage Systems

A DC microgrid has many advantageous features, such as low power losses, zero reactive power, and a simple interface with renewable energy sources (RESs). bipolar is also highlighted due to its high-power quality, improved reliability, enhanced system efficiency. However, the high bus voltage fluctuation load unbalance between poles. Therefore, this paper analyzes that can occur in microgrid. An autonomous grid regulation method introduced regulate of using distributed storage systems (ESSs). The proposed scheme ESSs could real time, regardless structure without external communication. Lastly, experimental results lab-scale prototype verified method.
