摘要
电力需求预测是进行电网规划非常重要的步骤,只有将电力需求可靠的预测才更便于电网进行供电。本文研究了二次指数平滑法模型,用于电力负荷预测中,结合经济、能源结构、环境等因素对中国社会用电量加以分析及预测,并进行了后验差检验,得到了很好的预测精度。
Power load forecasting is a very important step for grid planning, the reliable forecast of power load is convenient for the power supply by power grid. This paper studies the use of quadratic exponential smoothing model in power load forecasting. Combined with the economic, energy structure, environmental factors, this paper analyzes and forecasts Chinese social power consumption, and the posteriori difference test. The good prediction accuracy is obtained.
