Energy modelling is critical for addressing challenges such as integrating variable renewable energy and addressing climate impacts. This paper describes the updated code management structure and code updates, the revised community forum and the outreach activities that have built a vibrant community of practice around OSeMOSYS. The code management structure has allowed code improvements to be incorporated into the model, the community forum provides users with a place to ask and answer questions, and the outreach activities connect members of the community. Overall, these three pillars show how a community of practice can be built around an open source tool and provides an example for other developers and users of open source software wanting to build a community of practice.

能源建模对于应对挑战（例如整合可变的可再生能源和应对气候影响）至关重要。本文介绍了更新的代码管理结构和代码更新，修订的社区论坛和外展活动，这些活动围绕OSeMOSYS建立了一个充满活力的实践社区。代码管理结构允许将代码改进合并到模型中，社区论坛为用户提供了一个提问和回答问题的场所，外展活动将社区成员连接在一起。总体而言，这三个支柱显示了如何围绕开放源代码工具构建实践社区，并为希望构建实践社区的其他开发人员和开源软件用户提供了示例。
