This study addresses the load movement forecast modeling based on complex matrix interpolation of the S-transform (ST). In complex matrix of time-frequency representation of the ST, each row follows conjugate symmetric property and each column appears a certain degree of similarity. Based on these characteristics, a complex matrix interpolation method for the time-frequency representation of the ST is proposed to interpolate each row of the complex matrix based on the conjugate symmetric property, and then to perform nearest-neighbor interpolation on each column. Then with periodic extension for daily and yearly electric load movement, a forecast model employing the complex matrix interpolation of the ST is introduced. The forecast approach is applied to predict daily load movement of the European Network on Intelligent Technologies (EUNITE) load dataset and annual electric load movement of State Gird Corporation of China and its branches in 2005 and 2006. Result analysis indicates workability and effectiveness of the proposed method. <\/jats:p>","DOI":"10.1142\/s1793962314500111","type":"journal-article","created":{"date-parts":[[2014,1,24]],"date-time":"2014-01-24T07:24:22Z","timestamp":1390548262000},"page":"1450011","source":"Crossref","is-referenced-by-count":0,"title":["Complex matrix interpolation model of the S-transform for electric load movement forecast"],"prefix":"10.1142","volume":"05","author":[{"given":"Zong-Chang","family":"Yang","sequence":"first","affiliation":[{"name":"School of Information and Electrical Engineering, Hunan University of Science and Technology, Xiangtan, P.
