In standalone microgrids, the Battery Energy Storage System (BESS) is a popular energy storage technology. Because of renewable energy generation sources such as PV and Wind Turbine (WT), the output power of a microgrid varies greatly, which can reduce the BESS lifetime. Because the BESS has a limited lifespan and is the most expensive component …
The storage system includes a lead-acid battery, which can be replaced by a hydrogen storage system, and DC-DC buck-boost bidirectional converter [25, 26]. The first task of this system is to maintain a DC Link voltage at the desired value whatever the variation in the load or sources.
In case of a dc microgrid, bus voltages and in case of an ac microgrid the system voltage and frequency are the information sensed by each local droop controller and used subsequently to adjust output active (and/or reactive) power of a BESS or a generation unit. Figure 8 shows such control strategy for a given dc microgrid. As can be …
