复杂城市化因素下的饱和负荷预测模型
Saturated Load Forecasting Model Under Complex Urbanization Characteristics
摘要
Abstract
With advance and intensification of urbanization, power load in some big cities begins to present a feature of saturation. In this paper, a saturated load forecasting model under complicated urbanization characteristics is proposed. In this model, main urbanization factors influencing power load, i.e. population, economy and area, are analyzed. With regard to complicated data environment caused by diversified urbanization characteristics, principle component analysis and wavelet transform are used to get urbanization characteristics with low dimension and high independence principle components and their corresponding fundamental frequency components. Finally, saturation capacity and its corresponding time are given by constructing correlation models between principle components of urbanization characteristics and power load. Case study of Shanghai shows saturation point and growing point of power load in future and reveals mechanism of urbanization characteristics influencing saturated power load.关键词
