考虑经济因素的电力负荷预测初探

An Initial Study on Load Forecasting Considering Economic Factors

Hossein Sangrody, Ning Zhou

摘要:

提出了一种新的负荷预测目标函数和分位数回归算法。在LF中,正预测误差和负预测误差往往具有不同的经济影响。考虑到这一差异,提出了一种新的目标函数,对正、负预测误差进行不同的定价。QR用于找到所提出的目标函数的最优解。以新英格兰电网的归一化净负荷为例,将该方法与时间序列法、人工神经网络法和支持向量机法进行了比较。仿真结果表明,该方法比其他三种方法更有效地降低了LF误差的经济成本。

英文摘要:

This paper proposes a new objective function and quantile regression (QR) algorithm for load forecasting (LF). In LF, the positive forecasting errors often have different economic impact from the negative forecasting errors. Considering this difference, a new objective function is proposed to put different prices on the positive and negative forecasting errors. QR is used to find the optimal solution of the proposed objective function. Using normalized net energy load of New England network, the proposed method is compared with a time series method, the artificial neural network method, and the support vector machine method. The simulation results show that the proposed method is more effective in reducing the economic cost of the LF errors than the other three methods.
