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

the strengths of the PI, deadbeat, and repetitive controllers. The proposed current controller mitigates cross-

coupling effects and provides a wide control bandwidth, thereby ensuring quick, precise, and robust response

to system parameter variations. Moreover, the proposed controller provides an efficient disturbance rejection,

which presents a holistic solution for enhanced performance of the E-STATCOM. The proposed controller

not only overcomes the limitations of individual controllers, but also provides improved current regulation.

Experimental findings obtained using a three-phase E-STATCOM are presented to illustrate the efficiency

of the proposed technique.
