The invention belongs to the field of maintenance scheduling evaluation and optimization in the power system and relates to a multicycle and multidimensional integrated maintenance scheduling optimization and safety analysis method. The method comprises the following steps: determining the moment requiring maintenance scheduling optimization according to the safety evaluation result after computing the generating capacity loss and the load supply adequacy at all the moments; carrying out the first optimization process: analyzing the variation of the index of generating capacity loss and determining the maintenance scheduling needing to be adjusted; carrying out the second optimization process: firstly analyzing and determining the bus load insufficient in load supply adequacy in a period of time according to the determined period of time of maintenance scheduling optimization; determining the dangerous branches which reduce the load supply adequacy; computing the correlation between the maintenance and the da
