Embodiment 1

[0089] Embodiment 1, in order to verify the effect of the present invention on reducing energy consumption and carbon emissions, the historical data of a certain multi-energy region in my country from July 1, 2019 to August 20, 2019 (one month is recorded as 30 days) is selected as training The data is sampled once a day, with a total of 50 load data points. Carry out load training and forecasting of the planning scheme of the traditional planning scheme and the short-term power load forecasting model based on the attention mechanism, and compare the results of the two. The comparison effect is as follows Figure 4 , Figure 5 and Image 6 shown, where Figure 4 is the comparison chart of electric load forecasting effect, Figure 5 is the effect comparison chart of heat load forecasting, Image 6 It is the effect comparison chart of cooling load forecasting.

[0090] It can be seen from the figure that the effect of the short-term power load forecasting model based on the at...

Abstract

The invention relates to the field of energy planning, and discloses an integrated energy system planning method and a device thereof and terminal equipment. The integrated energy system planning method comprises the steps of collecting historical data of a region needing to be predicted, wherein the historical data comprises historical load data, historical distributed power supply output power, historical temperature and humidity, predicted day temperature and humidity and predicted day distributed power supply output power; establishing a high-dimensional data set according to the historical load data, the historical distributed power supply output power and the historical temperature and humidity; constructing a neural network model according to the attention mechanism, and training the neural network model based on the high-dimensional data set; inputting the predicted day temperature and humidity into the trained neural network model to obtain a load prediction result; and constructing an integrated energy system planning model according to the output power data of the distributed power supply on the prediction day, and performing integrated energy system planning based on the load prediction result and the integrated energy system planning model.

Description

technical field [0001] The invention relates to the field of energy planning, in particular to a comprehensive energy system planning method, device and terminal equipment. Background technique [0002] The integrated energy system can realize the coupling and complementarity of different energy sources in a certain area. By utilizing the complementarity and substitutability of energy sources, the coupling of different energy devices on the supply side can be realized, which can meet the needs of multiple loads and improve energy utilization efficiency. It can effectively To reduce energy costs, comprehensive energy system planning is inseparable from accurate load forecasting. Load forecasting refers to the prediction of future load and energy consumption based on a certain data basis, combined with a series of related influencing factors, and through a certain forecasting method. Correct and accurate forecasting can not only rationally adjust the energy supply plan to ens...
