    A Review of Modeling and Applications of Energy Storage Systems in Power Grids
    (Institute of Electrical and Electronics Engineers (IEEE), 2022-03-25) Calero, Fabian; Cañizares, Claudio A.; Bhattacharya, Kankar; Anierobi, Chioma; Calero, Ivan; Zambroni de Souza, Matheus F.; Farrokhabadi, Mostafa; Guzman, Noela Sofia; Mendieta, William; Peralta, Dario; Solanki, Bharatkumar V.; Padmanabhan, Nitin; Violante, Walter
    As the penetration of variable renewable generation increases in power systems, issues, such as grid stiffness, larger frequency deviations, and grid stability, are becoming more relevant, particularly in view of 100% renewable energy networks, which is the future of smart grids. In this context, energy storage systems (ESSs) are proving to be indispensable for facilitating the integration of renewable energy sources (RESs), are being widely deployed in both microgrids and bulk power systems, and thus will be the hallmark of the clean electrical grids of the future. Hence, this article reviews several energy storage technologies that are rapidly evolving to address the RES integration challenge, particularly compressed air energy storage (CAES), flywheels, batteries, and thermal ESSs, and their modeling and applications in power grids. An overview of these ESSs is provided, focusing on new models and applications in microgrids and distribution and transmission grids for grid operation, markets, stability, and control.

    Microgrid Stability Definitions, Analysis, and Examples
    (Institute of Electrical and Electronics Engineers (IEEE), 2019-06-28) Farrokhabadi, Mostafa; Canizares, Claudio A.; Simpson-Porco, John W.; Nasr, Ehsan; Fan, Lingling; Mendoza-Araya, Patricio A.; Tonkoski, Reinaldo; Tamrakar, Ujjwol; Hatziargyriou, Nikos; Lagos, Dimitris; Wies, Richard W.; Paolone, Mario; Liserre, Marco; Meegahapola, Lasantha; Kabalan, Mahmoud; Hajimiragha, Amir H.; Peralta, Dario; Elizondo, Marcelo A.; Schneider, Kevin P.; Tuffner, Francis K.; Reilly, Jim
    This document is a summary of a report prepared by the IEEE PES Task Force (TF) on Microgrid Stability Definitions, Analysis, and Modeling, IEEE Power and Energy Society, Piscataway, NJ, USA, Tech. Rep. PES-TR66, Apr. 2018, which defines concepts and identifies relevant issues related to stability in microgrids. In this paper, definitions and classification of microgrid stability are presented and discussed, considering pertinent microgrid features such as voltage-frequency dependence, unbalancing, low inertia, and generation intermittency. A few examples are also presented, highlighting some of the stability classes defined in this paper. Further examples, along with discussions on microgrid components modeling and stability analysis tools can be found in the TF report.
