Research on Medium-and Long-term Power Demand Trend of New-type Power System
With the rapid development of the modern new economy,the medium-and long-term power demand forecasting of new power systems has become a new challenge.In this paper,combining the growth characteristics of power demand,modeling the power demand development trend by using the nonlinear fitting of the S-shaped growth curve,and correcting the model by considering the saturated power,a medium and long-term load forecasting model with a generalized Sigmoid function is proposed.The model is verified to be generalized and valid through the arithmetic example of Yunnan historical data,which can provide a reference basis for subsequent medium-and long-term power demand forecasting.
