摘 要:随着能源互联网的发展和“电能替代”日渐兴起,区域负荷预测的严峻性日益突出。电网端各种全新的影响因素在新背景下持续显示出来,由此引发很多关于电网规划的不明确性因素,以往负荷预测方法在新环境下不再适用。文章基于出现在能源互联网背景下全新的影响因素,考虑新背景下电网预测的有关影响,结合电能替代背景下电动汽车的影响因素、风能太阳能等新能源的接入以及用户侧不确定因素的波动性,提出了一种基于传统负荷预测的适用于能源互联网的负荷预测模型,该模型使得负荷预测结果更加准确,为以后电网预测工作建立了更加准确的基础数据和前提保障。

Abstract: With the development of energy Internet and the rise of "electric energy substitution", the seriousness of regional load forecasting is becoming more and more prominent. A variety of brand-new factors at the power grid end continue to show under the new background, which leads to a lot of uncertain factors about power grid planning, and the previous load forecasting methods are no longer applicable in the new environment. In this paper, based on the new influencing factorin the context of energy Internet, considering the relevant influence of power grid forecasting under the new background, based on the influencing factor of electric vehicles in the context of electric energy substitution, the access of new energy such as wind and solar energy, and the volatility of uncertain factors on the user side, we proposed a load forecasting model suitable for energy Internet based on traditional load forecasting. The model makes the load forecasting results more accurate, thus establishing more accurate basic data and premise guarantee for the future power grid forecasting work.
Keywords: energy Internet; electric energy substitution; load forecasting
引言
如今能源的生产和消费模式在不断变化,基于这个现实背景下,学者们提出了能源互联网这个新型概念,在能源互联网背景下对于电力运行和发展都将带来巨大的影响。国家电网公司在适应新背景下的电网运行和发展工作中最为重要的环节就是负荷预测。随着能源互联网的逐步运行,供电侧各种全新的影响要素在新背景下逐步体现出来,由此引发更多电网预测的不准确性和波动性。对于以往的负荷预测模型只是对于某一特定影响因素的规划,对于新的背景之下的各类影响因素,传统的负荷预测模型无法完成。……
