Abstract In the electricity market, the transmission expansion planning faces influences of many uncertainties, which have the characteristic of random and fuzzy. In the past work, due to the limit in mathematical theory, the model developed could not simultaneously consider these two-fold uncertainties. Based on credibility theory accomplished recently, a new model with random fuzzy programming is proposed in this paper for transmission network expansion planning. The random fuzzy variable is adopted to describe the uncertain factors of newly-added generator bus output, the load of the newly-added bus, and the newly-added line investment. The random fuzzy simulation and improved quantum genetic algorithm are used to solve this model, and the model is proved effective through a 18-bus systems.

Key words： Transmission network planning two-fold uncertainty credibility theory random fuzzy simulation improved quantum genetic algorithm (IQGA)
