摘要

针对多回直流集中馈入的受端电网电压稳定问题,提出一种考虑负荷中心源荷匹配度的分区电压控制策略。首先,研究负荷中心的电力供需特性,以源荷匹配度为分区评价指标,建立基于K-均值算法的多直流馈入受端电网分区优化模型。然后,构建分区电压优化控制子模型,并采用同步交替方向乘子法（ADMM）对各子模型进行求解。最后,以Nordic32系统为基础进行改进,对所提出的分区电压控制方法进行仿真验证,仿真结果表明本文提出的电压控制策略能够在不同故障场景下对系统电压进行控制调节,并且具有电压平稳速度快的优势。

Abstract

Aiming at the voltage stability problem of receiving-end power grid with multi-circuit DC centralized feed, this paper proposes a partition voltage control strategy considering the source-load matching degree of load center. Firstly, the power supply and demand characteristics of the load center are studied, and the source-load matching degree is used as the partition evaluation index to establish a multi-infeed DC receiving-end power grid partition optimization model based on K-means algorithm. Then, the sub-model of voltage optimization control is constructed, and synchronous Alternating Direction Method of Multipliers （ADMM） algorithm is attached to the model to get the best voltage control result of each partition area. Finally, we adopted the Nordic 32 system, and modified it to verify the voltage controlling ability of the method we brought up. The simulation results review that the voltage partition control method we proposed would be capable of adjusting the system voltage under various circumstances and has the advantage of stable voltage in fast speed.
