Abstract

Abstract The electrical load from irrigation pumps is an important part of the overall electricity demand in many agricultural areas of the U.S. west. The date the pumps turn on and the total electrical load they present over the summer varies from year to year, partly because of climate fluctuations. Predicting this variability would be useful to electricity producers that supply the region. This work presents a contingency analysis and linear regression scheme for forecasting summertime irrigation pump loads in southeastern Idaho. The basis of the predictability is the persistence of spring soil moisture conditions into summer, and the effect it has on summer temperatures. There is a strong contemporaneous relationship between soil moisture and temperature in the summer and total summer pump electrical loads so that a reasonable prediction of summer pump electrical loads based on spring soil moisture conditions can be obtained in the region. If one assumes that decision makers will take appropriate acti...

爱达荷州第九气候区灌溉泵电负荷与当地气候的关系
在美国西部许多农业区,灌溉水泵的电力负荷是总电力需求的重要组成部分。水泵启动的日期和整个夏季的总电力负荷每年都在变化,部分原因是气候的波动。预测这种变化对为该地区供电的电力生产商很有用。这项工作提出了一种预测爱达荷州东南部夏季灌溉泵负荷的应急分析和线性回归方案。可预测性的基础是春季土壤水分状况持续到夏季,以及它对夏季气温的影响。夏季土壤湿度、温度与夏季水泵总电负荷之间存在较强的同期关系,可以根据春季土壤湿度条件对该地区夏季水泵总电负荷进行合理预测。如果人们认为决策者会采取适当的行动……
