Application of the Improved Grey Model in Power Load Forecasting

摘要

This paper presents an improved grey model used in power load forecasting. In order to overcome the limitation of the traditional grey model GM(1,1), vector θ is introduced to modify the calculating formula for background sequence value in grey model and build a more adaptable model. Using artificial fish school algorithm can solve the value of vector θ. It reflects that the improved model has higher accuracy of load forecasting and has wider application by cases analysis.
