Micro-grid systems utilizing renewable energy sources (RES) have emerged as a viable technology for addressing the present global climate crisis. Nonetheless, the considerable uncertainty of RES and the climatic variability make it challenging to build a suitable system. To understand the implications of climate on the optimal micro-grid design, we present a techno-economic analysis of 13,488 regions. On the basis of climatic similarities, the locations were divided into nine groups, and the correlations between climates and optimal designs were analyzed. Based on their climate sensitivity and the change trend of two climates, we discovered that they fell into four separate categories. In climate-sensitive places where PV module size increases 6.79 ± 0.13% and wind turbine size increases at the same rate, the overall cost increases 7.6%, which is 2–4 times that of other types. On the other side, climate-insensitive locations with same/opposite tendencies experience the least change in overall micro-grid system size due to climate change. Although total system sizes are most sensitive in climate-sensitive regions with opposing tendencies, their total costs vary the least due to a trade-off between PV module and wind turbine size variations. The analyses reveal the effects of climate on the sizes and costs of micro-grid systems and emphasize the importance of considering climatic fluctuations when designing micro-grid systems.

利用可再生能源 (RES) 的微电网系统已成为解决当前全球气候危机的可行技术。尽管如此，RES 的相当大的不确定性和气候多变性使得构建合适的系统具有挑战性。为了解气候对最佳微电网设计的影响，我们对 13,488 个地区进行了技术经济分析。在气候相似性的基础上，将地点分为九组，并分析了气候与优化设计之间的相关性。根据它们的气候敏感性和两种气候的变化趋势，我们发现它们分为四个不同的类别。在气候敏感的地方，光伏组件尺寸增加 6.79 ± 0.13%，风力涡轮机尺寸以相同的速度增加，总成本增加 7.6%，是其他类型的 2-4 倍。另一方面，由于气候变化，具有相同/相反趋势的气候不敏感位置的整体微电网系统规模变化最小。尽管总系统尺寸在具有相反趋势的气候敏感地区最敏感，但由于光伏模块和风力涡轮机尺寸变化之间的权衡，它们的总成本变化最小。分析揭示了气候对微电网系统规模和成本的影响，并强调了在设计微电网系统时考虑气候波动的重要性。尽管总系统尺寸在具有相反趋势的气候敏感地区最敏感，但由于光伏模块和风力涡轮机尺寸变化之间的权衡，它们的总成本变化最小。分析揭示了气候对微电网系统规模和成本的影响，并强调了在设计微电网系统时考虑气候波动的重要性。尽管总系统尺寸在具有相反趋势的气候敏感地区最敏感，但由于光伏模块和风力涡轮机尺寸变化之间的权衡，它们的总成本变化最小。分析揭示了气候对微电网系统规模和成本的影响，并强调了在设计微电网系统时考虑气候波动的重要性。
