摘　　要：Battery energy storage systems(BESSs)are a kind of important asset for power systems with high integration levels of renewable energy,and they can be controlled to provide various critical services to the power grid.This paper presents the real-world experience of using a megawatt-scale BESS with grid-following(GFL)and grid-forming(GFM)controls and a run-of-river(ROR)hydropower plant to restore a regional power system.To demonstrate this,we carry out power-hardwarein-the-loop experiments integrating an actual GFL-or GFM-controlled BESS and a load bank.Both the simulation and experimental results presented in this paper show the different roles of GFL-or GFM-controlled BESS in power system black starts.The results provide further insight for system operators on how GFL-or GFM-controlled BESS can enhance grid stability and how an ROR hydropower plant can be converted into a black-start-capable unit with the support of a small-capacity BESS.The results show that an ROR hydropower plant combined with a BESS has the potential of becoming one of enabling elements to perform bottom-up black-start schemes as opposed to conventional bottom-down method,thus enhancing the system resiliency and robustness.
