Abstract: At present, the analysis on the theoretical model of the cost of fuel collection, processing, storage and transportation of domestic straw power plant is blank in the national area. In order to effectively control such cost and comprehend the changing tendency of the cost of raw straw and straw bale with different transportation distances, this paper established a model of the cost of fuel collection, processing, storage and transportation of domestic straw power plant, which was based on the data of the existing domestic power plants. By analyzing the changing tendency of the cost under different models and the fuel purchase of straw power plant with diverse purchase amount and radii, the paper proposed a superior model, which was meaningful and constructive in directing the construction of reasonable fuel collection, processing, storage and transportation model for different straw power plants as well as effectively reducing the cost of fuel.
