Abstract

In this paper, a study is conducted to solve voltage problems that may occur, when large-scale Distributed Generations (DGs) and Electric Vehicles (EVs) are connected to the distribution system, through coordinated control between DGs and EVs. Using the Graph Search Method (GSM), the voltage problem was solved through the reactive power control of EVs and DGs in the near area where the voltage problem occurred. As a result, it was possible to obtain a result with high robustness against the change of the topology and reduction of the total loss of distribution system. In addition, when the voltage problem cannot be solved by only reactive power control, the active power control was performed for EVs and DGs included in a specific divided system of the conventional distribution system using the GSM to maintain the voltage within the normal range. Finally, to verify the performance of the proposed method, the whole algorithm was implemented by linking the Open Source Distribution System Simulator (OpenDSS), and the MATLAB.

开发基于图谱搜索法的电动汽车与 DG 电压调节协调控制方法

本文研究了当大规模分布式发电（DGs）和电动汽车（EVs）接入配电系统时，通过 DGs 和 EVs 之间的协调控制来解决可能出现的电压问题。利用图搜索法（GSM），通过对发生电压问题的附近区域的电动汽车和分布式发电设备进行无功功率控制，解决了电压问题。因此，可以获得对拓扑变化具有较高鲁棒性的结果，并减少了配电系统的总损耗。此外，当电压问题无法仅通过无功功率控制来解决时，还利用 GSM 对传统配电系统的特定划分系统中包含的电动汽车和 DG 进行了有功功率控制，以将电压维持在正常范围内。最后，为了验证所提方法的性能，通过连接开源配电系统仿真器（OpenDSS）和 MATLAB 实现了整个算法。
