Renewable Energy Systems have been in the spotlight of the academic and industrial research for more than two decades, thanks to the development of several fields related to the Electrical Engineering. More recently, with the increasing complexity of the individual renewable energy systems and the interconnection to the grid, the scientific panorama has been witnessing to a convergence of different topics, which span across several IEEE-IES thematic areas: power electronics, electrical machines, smart grids, energy storage, transportation electrification and aerospace. After a brief overview of the renewable energy technologies, this work deals with how the convergence of multiple technologies developed to provide marginal support to the grid has evolved into the foundation of the future utility grid and expanded to transportation sector. It will be shown how the design of a renewable energy system cannot prescind anymore from the electrical grid and from the ancillary services that are requested. Example of convergence are given for a smart transformer application and for a transportation application.

可再生能源系统在重塑电网场景中的作用


二十多年来，由于与电气工程相关的多个领域的发展，可再生能源系统一直是学术和工业研究的焦点。最近，随着单个可再生能源系统的复杂性和与电网的互连，科学全景见证了不同主题的融合，这些主题跨越多个 IEEE-IES 主题领域：电力电子、电机、智能电网、能源存储、交通电气化和航空航天。在简要概述可再生能源技术后，本文讨论了为电网提供边际支持而开发的多种技术的融合如何演变成未来公用电网的基础并扩展到交通运输领域。它将展示可再生能源系统的设计如何不能再与电网和所需的辅助服务相区别。给出了智能变压器应用和交通应用的收敛示例。
