Energy-storage-equipped static synchronous compensators (E-STATCOM) are crucial devices in a modern

power grid to regulate both the active and reactive power, thereby improving the efficiency and power

quality. Current controllers commonly used with E-STATCOM devices include proportional-integral (PI),

repetitive, and deadbeat controllers. However, each has application-dependent restrictions and therefore lack

the ability to achieve optimal operation. This paper presents a novel hybrid current controller that combines
