Abstract
: This paper presents a method to improve the voltage stability of a distribution system that is integrated by renewable power generations and interconnected by microgrids, which can be expected to appear in the near future. Being impacted by the significant fluctuation of renewable powers, the distribution voltage may be considerably degraded along with the increasing integration of renewable power generations. However, even higher voltage quality is desirable in the modern society, and therefore, the voltage stabilization problem in the future distribution system comes to be a critical issue of concerns. In this paper, a new method is proposed to deal with this voltage stabilization problem by cooperated use of STATCOM (synchronous static compensator) and the reactive power control of interconnecting microgrids. With the proposed method, the reactive power from microgrids are controlled to mitigate the voltage change caused by the active power from these microgrids, and simultaneously, the STATCOM is actuated to suppress the voltage fluctuation originated from renewable power generators that are directly integrated into the distribution grid. In this paper, a STATCOM model of small capacity with relatively simple structure and low cost is proposed for distribution use, and the control systems for both the STATCOM and microgrids are designed as well. Digital simulations with a created typical future distribution system model are conducted in this study, and the simulations results have verified the voltage stabilization effects by the proposed method.
