摘要：

Low-frequency pulsating ripples exist on the input side of a single-phase inverter, which bring some adverse effects and harm to the inverter and photovoltaic power generation system. In order to suppress the low-frequency pulsating ripple and reduce the filter circuit parameters, a novel single-stage boost single-phase inverter is proposed, which can suppress low-frequency ripple. And a three-closed-loop compound control strategy that can suppress input low-frequency ripples under the limitation of an energy storage inductor current and buffer capacitor voltage is proposed. The circuit topology, control strategy, key circuit parameters design, system modeling, and simulation of the inverters are deeply analyzed and studied. Simulation and experimental results show that the inverter has a good ability to suppress input low-frequency ripples.

[3] Power Electronics Technology for Large-Scale Renewable Energy Generation Power electronics is the enabling technology for the grid integration of large-scale renewable energy generation, which provides high controllability and flexibility to energy generation, conversion, transmission, and utilization. However, power electronics also brings several challenges to conventional power grids, e.g., reducing the system inertia. Advanced control strategies have been developed to enhance the energy conversion process. In this article, the grid-integration structure and control for renewable energy are discussed with $a$ focus on large-scale wind, solar photovoltaic, and energy storage systems. Future research and development trends for these technologies are also presented. [J].
