摘　　要：大量分布式光伏电源的接入为配电系统的安全、经济运行带来了巨大挑战。针对配电系统线路损耗和电能质量问题,提出一种基于智能配电变压器的格状化配电系统架构。综合配电系统源-荷之间的功率关系与电能质量综合治理,构建格状化配电系统协调控制策略。最后,在MATLAB/Simulink中建立双节点系统模型进行仿真验证。仿真结果表明,所提格状化配电系统架构相较于其他传统架构降低了系统功率损耗、实现了电能质量治理功能。The integration of a large number of distributed photovoltaic power sources brings great challenges to the safe and economic operation of the distribution system.Aiming at the problem of line losses and power quality in the distribution system,a meshed distribution system architecture based on smart distribution transformer(SDT)is proposed.The coordinated control strategy for the meshed distribution system is constructed by synthesizing the power relationship between source-load and integrated power quality management in the distribution system.Finally,a two-bus system model is established in MATLAB/Simulink for simulation verification.The simulation results show that the proposed meshed distribution system architecture reduces the loss of system power and realizes the function of power quality management compared with other traditional architectures.
