摘要

首先，对柔性直流配电网的拓扑结构和节点类型进行了阐述。然后，提出了适用于柔性直流配电网的分层协调控制架构。系统级控制采用随机潮流嵌入的带精英策略非支配排序遗传算法，变流器级控制采用多级直流电压裕度控制，源荷设备级控制采用“拟鸡尾酒”源荷功率响应策略以减少端口功率控制误差。最后，在RTDS&dSPACE互联仿真平台上建立了柔性直流配电网仿真模型，通过仿真验证了所提分层协调控制策略的有效性。

Abstract

Firstly

a typical topology structure and node classification of flexible DC distribution network(FDCDN)are described. Secondly

a hierarchical coordinated control architecture for FDCDN is proposed. The system-level control adopts elite strategy based non-dominated sorting genetic algorithm with the embedded probabilistic load flow and the converter-level control uses multi-stage DC voltage margin control. The source-load-level control adopts the “quasi-cocktail” source-load response strategy to minimize the terminal power control error. Finally

a simulation model of FDCDN is established on the RTDS&dSPACE combined simulation platform. The effectiveness of the proposed hierarchical coordinated control strategy is proved by simulation.
