Abstract

The expansion of renewable energy in recent electric power systems has affected the associated networks, and their speed is gradually increasing. Renewable generators that do not have their own reserve capacity produce variable amounts of power that often generate balancing issues in grid operation. Therefore, a high penetration of the renewable generator is expected to impact on the stability of the power system greatly. As a countermeasure against these issues, a proposal has been derived to use the energy storage system (ESS) to contribute to the stability of the power system. An ESS, which is planned to be composed at the point of connection of renewable generators, must be evaluated in advance to meet its own objectives. In this paper, based on structural analysis, progress has been made in the development of a user-defined model dedicated to power system analysis tools for use in stability analysis. Based on IEEE 1547, the active response capability for ESS is configured and verified through the simulation based on PSS/e software tool.
