Assessment of power supply structure optimization by using kernel PCA-LINMAP

To deal with the limitation of the traditional Principal Components Analysis(PCA) in solving non-linear data,the assessment model of kernel Principal Component Analysis-Linear Programming Techniques for Multidimensional Analysis of Preference(KCPA-LINMAP) is proposed based on LINMAP.The model can also be used to obtain the weight of every index during assessment process,while the traditional PCA couldn't.The model was adopted to assess the power supply structure optimization which was characterized by numerous indices and low degree of interrelationship among them,and the assessment results for some area are given.The mainsteam direction of power supply structure optimization is also pointed out.
