Can battery energy storage systems improve microgrid performance?

This work was supported by Princess Sumaya University for Technology (Grant (10) 9-2023/2024). The successful integration of battery energy storage systems (BESSs) is crucial for enhancing the resilience and performance of microgrids (MGs) and power systems.

What is inverter disconnection?

Inverter disconnection occurs when the SoC falls below its lower limit at 35% . Additionally, to maintain system power balance and stability, the nominal output power remains constant at the nominal capacity when the SoC exceeds 85% .

How do mg inverters work?

Notably, it excels in adapting to rapid load changes, maintaining active power at the specified reference while dynamically adjusting reactive power for voltage stability, which is ideal for MGs with dynamic load profiles. The inverters’ reference output voltages (Vref) are determined using a power flow analysis on the system.

Can droop control improve the battery life of a Bess-fed inverter?

The proposed approach utilizes a droop control strategy to adjust the reference power of the BESS-fed inverter, potentially enhancing the battery’s cycle life, state of health, and remaining useful life by managing the SoC [27, 28].
