A Short-term Load Forecasting Method Based on Support Vector Machine with Whale Optimization Parameters
With the emergence of a large number of distributed energy stations and the popularity of electric vehicles
the security and economic operation of the power system are affected. At the same time
the traditional load forecasting methods are also facing challenges. To solve this problem
a Whale Optimization Algorithm-Least Squares Support Vector Machine (WOA-LSSVM) is proposed for short-term power system load forecasting. Using the advantages of whale algorithm such as strong global optimization ability and fast convergence speed
the blindness of parameter selection of LS-SVM is overcome
and the load forecasting accuracy of LS-SVM is improved. WOA-LSSVM is used to forecast the load of a certain area in Zhejiang province in the next day based on the historical load data in 2013. The results are compared with those of the particle swarm optimization least squares support vector machine model and the standard LSSVM model. The results show that the short-term load forecasting based on the whale optimization LSSVM has a higher forecasting accuracy and a smaller relative error.
