由于天然气消耗带来的一些问题，伊朗农业井有必要用电替代化石燃料。诸如缺乏适当和充足的燃料供应、空气和土壤污染、噪音污染以及安装、操作和维护费用巨大等问题意味着伊朗农业部门必须用电力消耗系统取代天然气石油系统。然而，在电力替代其他能源的今天，研究电力的需求是必要的。由于水井是农业部门的主要用电量，对能源需求函数的估计将有利于政策制定者实现其目标。本文研究了伊朗农业部门的能源需求函数。遗传算法techniques are appliedto estimate electricity demand in agricultural sector in three forms: linear, quadratic and exponential equations. Based on the conventional criteria, the exponential model is selected as the best model for estimation. Furthermore, electricity demand of agricultural sector is forecasted under three scenarios for years next three years.
