    Microgrid Modeling for Stability Analysis
    (Institute of Electrical and Electronics Engineers (IEEE), 2023-10-24) Espín-Sarzosa, Danny; Palma-Behnke, Rodrigo; Cañizares,Claudio A.; Annakkage, Udaya; Elizondo, Marcelo; Espina, Enrique; Du, Wei; Kabalan, Mahmoud; Meegahapola, Lasantha; Mendoza-Araya, Patricio A.; Nasr, Ehsan; Pavani, Ahda; Ramos, Rodrigo; Ropp, Michael; Schneider, Kevin P.; Simpson-Porco, John W.; Strunz, Kai; Taranto, Glauco; Tuffner, Francis; Reilly, James T.
    This document is a summary of a report prepared by the IEEE PES Task Force (TF) on Microgrid (MG) Dynamic Modeling, IEEE Power and Energy Society, Tech. Rep. PES-TR106, 2023. In this paper, the major issues and challenges in microgrid modeling for stability analysis are discussed, and a review of state-of-the-art modeling approaches and trends is presented. In the context of the IEEE 1547 standard, the document covers issues associated with component models for MG dynamic studies and simulations, including generator and grid modeling, full and average converter models, unbalanced and balanced system conditions, dynamic and static loads, protection requirements, and detailed and simplified controls considering communications delays, packet losses, and security issues. Considering the future integration of grids and MGs to form broad integrated networks, a discussion is presented of the use of phasor vis-à-vis electromagnetic transient simulation tools for MG dynamic stability studies, as well as modeling scale-up issues and MG equivalent models. Specifically white-, grey-, and black-box models, are presented. This TF paper and companion report constitute a modeling guide for R&D groups working on developments and standards of MGs with a focus on stability issues.

    Trends in Microgrid Control
    (Institute of Electrical and Electronics Engineers (IEEE), 2014-05-20) Olivares, Daniel E.; Mehrizi-Sani, Ali; Etemadi, Amir H.; Canizares, Claudio A.; Iravani, Reza; Kazerani, Mehrdad; Hajimiragha, Amir H.; Gomis-Bellmunt, Oriol; Saeedifard, Maryam; Palma-Behnke, Rodrigo; Jimenez-Estevez, Guillermo A.; Hatziargyriou, Nikos D.
    The increasing interest in integrating intermittent renewable energy sources into microgrids presents major challenges from the viewpoints of reliable operation and control. In this paper, the major issues and challenges in microgrid control are discussed, and a review of state-of-the-art control strategies and trends is presented; a general overview of the main control principles (e.g., droop control, model predictive control, multi-agent systems) is also included. The paper classifies microgrid control strategies into three levels: primary, secondary, and tertiary, where primary and secondary levels are associated with the operation of the microgrid itself, and tertiary level pertains to the coordinated operation of the microgrid and the host grid. Each control level is discussed in detail in view of the relevant existing technical literature.
