| description | Summary
This paper proposed an improved genetic algorithm‐based operational strategy for vanadium redox flow battery (VRB) energy storage systems (ESSs) in active distribution networks for improving the dynamic performances of batteries. Firstly, the accurate model of VRB considering the influences of external factors, such as temperature, electrolyte flow rate, ion exchange membrane, catalyst, polarization, self‐discharge, and leakage current are constructed. By the test of the accurate model, the dynamic performances Ф of VRB consisting of efficiency η, self‐discharge rate λ, utilization rate ψu, maximum discharge depth DoD, and cycle life κ are reasonably proposed. And then, the mathematical framework for the operational strategy optimization of ESSs was developed considering both the dynamic performances Ф and the external benefits of VRB ESSs. Finally, case studies based on a modified IEEE 123 Node Test Feeder verified the safe and reasonable operational states of battery ESSs with higher efficiencies, utilization rate, cycle life and lower self‐discharge rate, and maximum discharge depth. The dynamic performances of battery ESSs are enhanced by about 32.4%.
