摘要天气对经济的不同部门有着重要的影响。其中最敏感的是电力市场，因为电力需求与几个天气变量有关，主要是气温。这项工作分析了西班牙的电力负荷和每日气温之间的关系，使用人口加权温度指数。除了考虑到每日和每月的季节性影响以隔离天气对电力负荷的影响之外，由于社会经济因素，电力需求呈现出显着的趋势。结果表明，这种关系是非线性的，在18°C左右有一个±3°C的“舒适区间”和两个饱和点，超过这个饱和点，电力负荷不再增加。负荷对日气温的敏感性随时间沿着而增加，夏季的敏感性高于冬季，但冷季的敏感性总是高于冬季。
Abstract Weather has a significant impact on different sectors of the economy. One of the most sensitive is the electricity market, because power demand is linked to several weather variables, mainly the air temperature. This work analyzes the relationship between electricity load and daily air temperature in Spain, using a population-weighted temperature index. The electricity demand shows a significant trend due to socioeconomic factors, in addition to daily and monthly seasonal effects that have been taken into account to isolate the weather influence on electricity load. The results indicate that the relationship is nonlinear, showing a “comfort interval” of ±3°C around 18°C and two saturation points beyond which the electricity load no longer increases. The analysis has also revealed that the sensitivity of electricity load to daily air temperature has increased along time, in a higher degree for summer than for winter, although the sensitivity in the cold season is always more significant than in th...
