本文提出了一种灵活的分布式发电(DG)控制接口，用于智能电网的应用。主要目标是维护分层控制框架；在并网和孤岛模式转换过程中提供最小的控制功能切换，并在并网或孤岛模式运行期间最大化DG接口对网络和负载的干扰抑制性能。为了实现这些目标，提出了一种固定电压-电流串级控制结构，该结构具有基于内模控制的电压控制器和潮流控制器，以最大化分布式电源接口内的干扰抑制性能，并最大限度地减少控制功能切换。通过不同运行场景下的仿真结果，对所提出的控制方案的有效性进行了评估。
In this paper a flexible distributed generation (DG) control interface is being presents to be used in smart grid applications. The main objectives are to maintain hierarchical control framework; offer minimal control function switching during mode transition from grid connected and islanded modes and maximize the disturbance rejection performance of the DG interface against network and load during grid connected or islanded mode operations. To achieve these objectives, a fixed voltage-current cascaded control structure with robust internal model control-based voltage controller and a power flow controller is proposed to maximize the disturbance rejection performance within the DG interface and to minimize control function switching. The effectiveness of the proposed control scheme is evaluated via simulation results for different operating scenarios.
