In recent years, with the large‐scale access of distributed generation (DG), the line voltage of the distribution network will be offset, which will adversely affect users. This paper aims at the voltage adjustment of the distribution network. Firstly, the reactive power control methods of distributed static synchronous compensator (DSTATCOM) and electric spring (ES) are studied separately, and then a layered cooperative control strategy based on them is proposed, which combines centralized compensation and distributed compensation to stabilize the entire line voltage. The upper layer aims at optimizing the comprehensive factors including voltage offset, user comfort and cost, and applies the dynamic adaptive particle swarm optimization (DAPSO) algorithm to study the optimal scheme of voltage adjustment. The lower layer designs the control loops of the compensation devices in response to the reactive power instruction. Finally, simulation results show that the voltage of the distribution network is effectively controlled. © 2020 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

基于DSTATCOM和ES的配电网协同电压控制方法。

近年来，随着分布式发电（DG）的大规模接入，配电网络的线路电压将被抵消，这将对用户产生不利影响。本文针对配电网的电压调整。首先分别研究了分布式静态同步补偿器（DSTATCOM）和电弹簧（ES）的无功控制方法，然后提出了基于它们的分层协调控制策略，该方法将集中补偿和分布式补偿相结合来稳定整条线路电压。上层旨在优化电压偏移，用户舒适度和成本等综合因素，并应用动态自适应粒子群优化（DAPSO）算法来研究电压调整的最佳方案。较低层响应无功功率指令设计补偿装置的控制回路。最后，仿真结果表明，配电网的电压得到了有效控制。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
