Characteristics and operational control strategies of grid‐forming long‐/short‐duration energy storage systems: A review

open access: yesEnergy Conversion and Economics, Volume 7, Issue 2, Page 127-148, April 2026.
Abstract Energy storage systems (ESSs) are increasingly critical for maintaining the stability and flexibility in power systems with rising renewable penetration. Grid‐forming (GFM) ESSs have emerged as a pivotal technology, capable of providing essential voltage and frequency support by establishing grid references in converter‐dominated systems. This

New controlled switching approach for limitation of transmission line switching overvoltages

open access: yesIET Generation, Transmission & Distribution, 2013
In this study, a new controlled switching approach is proposed. This method is applied to the controlled closing of high voltage uncompensated transmission lines. The new approach is a developed version of conventional zero‐crossing controlled switching approach. Performance of the new approach is evaluated and compared with the conventional controlled
