The growing complexity of distributed energy systems and the rise of peer-to-peer energy markets demand innovative solutions for efficient, resilient, and sustainable energy management. However, existing research often remains fragmented, with limited integration between control strategies, optimization frameworks, and practical implementation. This paper presents a comprehensive systematic review, following the PRISMA methodology, that synthesizes findings from 94 high-quality studies and addresses the lack of consolidated insights across technical, operational, and architectural layers. This review highlights advancements in six key areas: optimization and modeling, multi-agent systems, simulations, blockchain and smart contracts, robust frameworks, and electric machines. Despite progress, several studies reveal challenges related to scalability, data privacy, computational complexity, and system adaptability, particularly in dynamic and decentralized environments. Stochastic–robust optimization and multi-agent systems improve decentralized coordination, while blockchain enhances security and automation in peer-to-peer trading. Simulations validate energy strategies, bridging theory and practice, and electric machines support renewable integration and grid flexibility. The synthesis underscores the need for unified frameworks that combine artificial intelligence, predictive control, and secure communication protocols. This review aims to provide a roadmap for advancing distributed energy systems toward scalable, resilient, and sustainable energy solutions.

The implementation of residential distributed generation (DG) in South America has shown significant growth in the last decade, driven by increased research on photovoltaics and renewable energy sources. Regulatory policies and business models have been crucial in fostering the adoption of DG in the region, with residential self-supply being the most receptive sector for implementing the concept. This article presents a literature review on DG as applied to residential self-supply in South America by comprehensively analyzing documents published between 2013 and 2023, applying the PRISMA methodology. In total, 37 literature resources have been systematically selected and reviewed to contribute to the identification of trends and developments in the field of DG in the residential sector, as well as to highlight areas that require further research and attention from stakeholders, including policymakers, investors, technology providers, and consumers in the South American context.

Este artículo presenta una revisión sistemática de literatura relativa al tópico reutilización de baterías de vehículos eléctricos (BVE) para aplicaciones de segunda vida en sistemas eléctricos de potencia. El fin del ciclo de vida de estas baterías representa un gran problema ambiental debido a su composición y materiales. El estudio tiene por objeto analizar la reutilización de las BVE como una alternativa sostenible para el medioambiente y, además, para brindar servicios complementarios que faciliten la incorporación de generación renovable no convencional de carácter intermitente a la red eléctrica. A través de una búsqueda exhaustiva de publicaciones científicas indexadas en catálogos digitales prestigiosos y de su posterior tratamiento sistemático, se ha llegado a un número selecto de 49 artículos científicos publicados entre 2018 y 2023. En ellos ha sido posible identificar las diferentes oportunidades, beneficios y limitaciones de los sistemas de almacenamiento de energía de segunda vida orientadas a impulsar una economía circular. El estudio concluye que, si bien la reutilización de baterías no está plenamente tratada ni implementada, debido a que aún enfrenta desafíos en términos de tecnología, costos y regulaciones, es de gran importancia profundizar su análisis para mejorar la eficiencia y disminuir los impactos ambientales que provocan su fabricación, uso y desecho.

Implementing Energy Storage Systems (ESS) is increasingly significant in power electrical systems. This is attributed to their ability to store surplus electricity generated by renewable energy sources such as wind and solar, contributing to the balance between generation and demand. Literature studies indicate that this practice enhances network stability and diminishes the need for expensive redesigns in infrastructure. This paper presents an exhaustive experimentation-based study of the dynamic response provided by three energy storage system technologies: supercapacitors, Lithium-Ion batteries, and Vanadium redox flow batteries, technologies with significant academic, research, and industrial interests nowadays. The objective of this research is the experimental evaluation of the performance of such technologies in real electrical system operations, focusing on determining the efficiency of charge and discharge, as well as the tracking of active and reactive power achieved through the associated grid interface. The experimental tests performed in a microgrid laboratory show these technologies’ advantages and limitations in different grid-integration applications, with the Lithium-Ion battery-based ESS demonstrating the highest efficiency and faster power response. The results achieved and reported in the article can serve as an essential input for researchers and technology developers to feed their models with more precise parameters and data that might provide results closer to the actual behaviour of the studied prototypes. The methodological framework used in this research is descriptive, experimental, and quantitative.
