Yes, energy storage systems can help mitigate voltage flicker in microgrids. Here’s how they contribute:
- Voltage Regulation: Energy storage systems can regulate voltage levels by injecting or absorbing power as needed, which helps stabilize the system and reduce fluctuations that may cause voltage flicker.
- Compensating for Renewable Fluctuations: Microgrids often include renewable energy sources like solar or wind, which can introduce variability into the power supply. Energy storage systems can buffer these fluctuations by storing excess energy when generation is high and supplying it when generation is low, thus mitigating voltage flicker.
- Hybrid Systems: The use of hybrid energy storage systems (HESS), combining technologies like batteries and supercapacitors, is particularly effective. Batteries provide long-term energy balance, while supercapacitors offer rapid power injection to mitigate sudden voltage fluctuations.
Overall, energy storage is crucial for maintaining stable and reliable power delivery in microgrids by reducing voltage and frequency variations, including those that cause voltage flicker.
