Abstract

The invention relates to a regional power load prediction method. The prediction method comprises the following steps: step 1, acquiring power load historical data of a corresponding acquisition area;step 2, establishing an RNN (Recurrent Neural Network) prediction model for power load prediction, and optimizing the RNN prediction model by using a hybrid locust optimization algorithm; and step 3,substituting the historical data into the RNN prediction model to obtain a power load prediction value of the acquisition area. The hybrid locust optimization algorithm is used to optimize the neuralnetwork model to predict the power load. Prediction precision is substantially improved. Problems of large power prediction model training samples and many network adjustable parameters established based on statistical data in a traditional scheme are solved, effective reference is provided for reasonable optimization of use of electric power resources, and electric energy transmission and supplyare balanced.

Description

technical field [0001] The invention relates to the field of power load forecasting, in particular to a regional power load forecasting method and system. Background technique [0002] With the rapid growth of population and rapid economic development, the electricity consumption of residential buildings has increased significantly. In order to balance electricity supply and demand and reduce carbon emissions, the development of smart buildings and smart grids has received more and more attention. At the same time, the intermittence and volatility of renewable energy have a certain impact on the power grid. With the increase of smart electricity terminals in residential buildings, residential electricity consumption has stronger volatility and randomness, which will affect the balance of supply and demand of electricity. Therefore, reliable and accurate load forecasting is of great significance, which helps to realize the dynamic planning and efficient management of smart ...
