Abstract For multi-objective reactive power optimization, there are plenty of objective- converting methods (OCMs) that can be used to convert multiple objectives into a single one. In the literature, however, there lacks study concerning the internal relations between different OCMs. In this paper, contour line, a common concept in geography, is introduced to compare and classify OCMs in multi-objective reactive power optimization. By drawing contour lines of different OCMs in objective function space, search directions of OCMs are discussed in terms of geometric meaning. In addition, according to the approximate Pareto solutions, locations of the optimal solutions are discussed. Furthermore, based on the shapes and characteristics of contour lines, different OCMs are compared and classified.

Key words： Reactive power optimization multi-objective optimization contour lines fuzzy theory Pareto optimality
