This work presents a three-phase, four-wire grid-integrated PV-hybrid energy storage system (HESS) controlled by a predictive dead-beat control. With faster dynamics and enhanced steady-state response, the predictive dead-beat control emphasizes quick error reduction between reference and grid currents for generating inverter switching signals. The proposed control enables the system to perform active and reactive power control, harmonics elimination, neutral current compensation, and load balancing at the point of common coupling (PCC) to maintain DC bus and AC bus voltage stability, even during dynamic conditions. The presented system is observed under steady-state and various dynamic state conditions, i.e., irradiation variation, grid voltage sag/swell, and load unbalancing. The HESS consists of a battery and ultracapacitor, collectively providing optimal energy and power density balance during dynamic conditions at the DC bus. The presented system’s performance is satisfactory per IEEE1547-2017 standards at the PCC.

摘要

This work presents a three-phase, four-wire grid-integrated PV-hybrid energy storage system (HESS) controlled by a predictive dead-beat control. With faster dynamics and enhanced steady-state response, the predictive dead-beat control emphasizes quick error reduction between reference and grid currents for generating inverter switching signals. The proposed control enables the system to perform active and reactive power control, harmonics elimination, neutral current compensation, and load balancing at the point of common coupling (PCC) to maintain DC bus and AC bus voltage stability, even during dynamic conditions. The presented system is observed under steady-state and various dynamic state conditions, i.e., irradiation variation, grid voltage sag/swell, and load unbalancing. The HESS consists of a battery and ultracapacitor, collectively providing optimal energy and power density balance during dynamic conditions at the DC bus. The presented system’s performance is satisfactory per IEEE1547-2017 standards at the PCC.
