对数回归方程 LogarithmRegress.cs 方程模型为 Y=a*LnX+b public override double[] buildFormula() 得到系数数组，存放顺序与模型系数相反，即该数组中系数的值依次是b,a。 public override double Forecast(double x) 预测函数，根据模型得到预测结果。 public override double computeR2() 计算相关系数（决定系数），系数越接近1，数据越满足该模型。

灰色预测模型（Gray Forecast Model）是通过 少量的、不完全的信息，建立数学模型并做出预 测的一种预测方法.当我们应用运筹学的思想方法 解决实际问题，制定发展战略和政策、进行重大 问题的决策时，都必须对未来进行科学的预测. 预测是根据客观事物的过去和现在的发展规律， 借助于科学的方法对其未来的发展趋势和状况进 行描述和分析，并形成科学的假设和判断.

Under the Energy Independence and Security Act of 2007 (EISA), the National Institute of Standards and Technology (NIST) was assigned “primary responsibility to coordinate development of a framework that includes protocols and model standards for information management to achieve interoperability of Smart Grid devices and systems…” [EISA Section 1305]. 35 This responsibility comes at a time when the electric power grid and electric power industry are undergoing the most dramatic transformation in many decades. Very significant investments are being made by industry and the federal government to modernize the power grid. To realize the full benefits of these investments—and the continued investments Forecast for the coming decades—there is a continued need to establish effective smart grid 36 standards and protocols for interoperability.
