Considering that parallel inverters systems often face with various disturbances, this study proposes a new adaptive robust control strategy for a voltage-current dual-loop to enhance system
This paper focuses on the three-level Buck-Boost Bi-directional converter (TL Buck-Boost BDC) applied in energy-storage inverters serving as charging or discharging circuit for storage battery. Based on
Conventional photovoltaic-storage virtual synchronous generators (VSG) often suffer from active power overshoot, frequency oscillations, and limited stability during grid-connected
The typical structure and control strategy of double-terminal AC-DC distribution systems under master-slave control is introduced.
In this article, a dual-loop continuous control set model predictive control (CCS-MPC) method is proposed for high-voltage and high-power energy storage system (ESS) based on dc dynamic voltage regulator (dc-DVR).
In this study, based on the hybrid energy storage system of battery-supercapacitor, a dual-loop compensation method is proposed. First, the small-signal model and output impedance matrix are built in d
It implements a dual loop Inverter control strategy for stand-alone microgrid to compensate voltage and frequency deviation and provides virtual inertia to control the high overshot in frequency transient during
This study focuses on an improved dual-buck topology for energy storage inverters, addressing challenges such as switching losses, leakage currents, and seamless grid integration.
Therefore, this paper proposes a seamless transfer control strategy based on a unified control structure, which comprises a voltage outer loop and a current inner loop.
