Power load forecasting method in multi-energy coupling mode

A load forecasting method based on a multi-energy coupling scene, comprising the following steps:

• Step 1, establishing a multilevel indicator system of key influencing factors of load demand in a multi-energy coupling mode, and collecting corresponding data sets according to key influencing factors in the indicator system;
• Step 2, extracting key influencing factors most correlated with a total load demand and a total supply of multi-energy coupling load in the indicator system established in step 1 respectively by using a maximum and minimum redundancy method, removing surplus influencing factors with redundancy information, and finally obtaining the key influencing factors influencing the total load demand and the total supply of the multi-energy coupling load;
• Step 3, normalizing the data of the key influencing factors extracted in step 2, and initializing population characteristic parameters of an AFWA adaptive firework algorithm;
• Step 4, based on the key influencing factor data normalized in step 3 and initialized population characteristic parameters of the AFWA adaptive firework algorithm, forecasting regional total power demand and regional coupling power supply respectively by using LSSVM optimized by AFWA algorithm;
• and
• Step 5, based on forecast results of the regional total power demand and the regional coupling power supply in step 4, forecasting a net power load demand of the regional coupling power supply.
