The rise of Distributed Energy Storage (DES) installations aligns with the growing prominence of Distributed Generation Sources (DGS), Distributed Energy Resources (DER), and Electric Vehicles (EV). Initially designed for single-purpose tasks, such as mitigating intermittency and facilitating the smooth integration of DER/DGS/EV operations, DES has evolved for multiple purposes in modern power grids. This paper explores the transition from plug-and-play, inverter-based resources to a collective approach that harnesses the potential of DES to benefit both the power grid and industries.
(1) Grid Quality: Reactive Power Compensation – Utilizing DES for reactive power compensation to enhance the quality of both current and voltage during disturbances and sudden changes in the power grid.
(2) Harmonic and unbalance Rejection-Employing DES to reject harmonics/unbalance and improve power reliability under varying conditions.
(3) Grid Stability: Frequency Regulation – Harnessing DES capabilities for a rapid response to frequency fluctuations, contributing to grid stability.
(4) Voltage Support – Employing DES to provide voltage support, aiding in maintaining a stable grid.
(5) Grid Optimization: Peak Shaving – Using DES to store excess energy during periods of low demand and releasing it during peak demand, contributing to grid optimization.
(6) Load Leveling – Leveraging DES to balance the load on the grid, ensuring efficient energy distribution.
As we explore these applications, the seminar aims to shed light on the transformative potential of a collective network of DES systems. The integration of these systems into various facets of the power infrastructure promises improved grid stability, enhanced power quality, and optimized grid operations, fostering a more resilient and sustainable energy landscape.
