As the transition towards a more sustainable, distributed energy model has continued to gather pace, the number of Smart Local Energy Systems (SLES) projects has increased. Ranging in age, size, location and complexity, these projects have faced a series of technical, social and economic challenges, with varying degrees of success. This paper presents the results of a systematic, state-of-the-art literature review with the aim of identifying the main technical barriers experienced by SLES in the UK. Originality is provided in the discussion of the key barrier areas identified during the review, which include those posed by multi-vector integration, grid connection, energy storage, smart technology and electric vehicles. The site-specific nature of SLES is identified as limiting the applicability of specific technical barriers, as is the need to view technical barriers within their respective social, economic and regulatory contexts. From the findings emerge three fundamental underlying technical challenges which face all SLES: diversity, uncertainty and integration. The findings also indicate that a more detailed understanding of site and context-specific barriers – and the relationships between them – is required in order to facilitate the mitigation or removal of technical barriers to the upscaling of SLES.

随着向更可持续，分布式能源模型的过渡不断加快，智能本地能源系统（SLES）项目的数量也在增加。这些项目的年龄，规模，位置和复杂性各不相同，它们都面临着一系列技术，社会和经济挑战，并取得了不同程度的成功。本文介绍了系统的，最新的文献综述的结果，目的是确定英国SLES遇到的主要技术障碍。在审查过程中确定的关键障碍领域的讨论中提供了独创性，其中包括多矢量集成，并网，储能，智能技术和电动汽车带来的障碍。SLES的特定于站点的性质被认为限制了特定技术障碍的适用性，以及在各自的社会，经济和法规环境中查看技术壁垒的需求。从调查结果中得出了所有SLES面临的三个基本的潜在技术挑战：多样性，不确定性和整合。调查结果还表明，需要对站点和特定于上下文的障碍及其之间的关系有更详细的了解，以便于减轻或消除升级SLES的技术障碍。
