Abstract: This paper presents a method to improving the voltage stability of a distribution system integrated with renewable power generations and interconnected by microgrids, which can be expected to appear in the near future. Because of the increasing integration of renewable power generators, the distribution voltage may be considerably degraded by the fluctuation caused by such power generators. 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. Using the proposed method, the reactive power from the microgrids is controlled for mitigating the voltage change caused by the active power of these microgrids. Simultaneously, the STATCOM is activated to suppress the voltage fluctuation originating from renewable power generators 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.
Keywords: distribution system, microgrid, reactive power control, renewable power generations, STATCOM, voltage stabilization
