Utilizing additional devices for small signal stability enhancement of power systems is crucial over the last few years due to increasing number of demand, uncertainty of load and integrating intermittent power system based on renewable energy. Among the number of additional devices in power system, energy storage is becoming more popular in last few decade. This paper investigates the impact of different types of energy storage on the small signal stability of power system. In order to analyze the impact of aforementioned energy storage for small signal stability, a single power system connected to an infinite bus is used as a test system. The eigenvalue and damping ratio of the investigated mode are used to examine the impact of energy storage on dynamic behavior of the investigated system. Furthermore, a time domain simulation is used to validate the eigenvalue analysis of the system. From the simulation, it is found that the type of energy storage have significant influence on the small signal stability of power system, indicated by the increasing value of damping over the system. © 2017 IEEE.
