Micro-Grid’s Primary Frequency Control by Supporting Vehicle-to-Grid Concept

Micro Grids as one of the most significant parts of Smart Grids must be able to maintain their stability following likely disturbances by optimal handling of their existing resources. In large power systems, frequency distortions are covered suitably due to sufficient spinning reserve all over the grid. But in micro grids because of either the limitations of generation resources and uncontrollability of the most part of them, occurring a relatively large disturbance will result in a significant oscillation of frequency. Vehicle-to-Grid (V2G) is being introduced by new researches as one of the new future resources which make them more noticeable than ever. In this article, the participation of V2G in primary frequency control (PFC) of micro grids is evaluated and it has been shown that the increasing of the penetration of V2Gs has significant impact on PFC of micro grids. V2Gs are recognized for their improving effect on PFC due to their capability of swift response to large disturbances because they are so quick to change their power output in accordance with the size of disturbances. The abovementioned issues are verified according to simulation of 9- bus Anderson micro grid.
