The invention discloses a disperse
relaxation factor tidal current model based minimum
electricity generating cost incremental quantity obtaining method. When a minimum
electricity generating cost incremental quantity model only containing one balance node
tidal current model is solved, the total demand unit change of a
system is fixed on a balance node, and an obtained
lambda, namely
electricity generating cost minimum incremental quantity cannot reflect actual operation of the
system in most cases during total demand unit change of a
system. The disperse
relaxation factor tidal current model based minimum electricity generating cost incremental quantity obtaining method adopts solves the provided model by means of an original antithesis
interior point method, and the
lambda of the system is controllable according to selected disperse relaxing factors.
