Bi-directional Extensible Converter and Its Distributed Control Strategy for Battery Energy Storage Grid-connected System
摘要
Abstract
With the expansion of the battery energy storage system in size, the traditional centralized converter can no longer satisfy the need of the development of it, and the distributed modular converter become the main development trend. The paper proposed a bi-directional extensible converter and its composition and extention forms for battery energy storage grid-connected system. On this basis, a bi-directional converter principle, which is different from that of the traditional conventer of battery energy storage system, was analyzed. It controls the value and direction of power by changing amplitude and phase-angle difference between two voltage sources with better static and dynamic performances. In order to avoid the shortages of the traditional centralized control method, the distributed control strategy of bi-directional extensible converter was proposed, in which grid-side and battery-side converters were respectively designed to work in passive and active power control. Therefore, the competition of controllers in power regulation was avoided and decoupling control between grid-side and battery-side converters was achieved while converter operating in a unity power factor state. Both simulation and experimental results are consistent with theoretical analyses, and the converter can work properly in both steady and transient processes.关键词
