The Method And Application Of Fixed Cost Allocation In Grid Corporation

As electric power market reform further develops, the reform of retail price has become a significant part. In the competitive market, the electric power companies allow all the users including the power plants and customers to use the electric network in an open and fair way, and transmit the high-quality electric energy economy to the electricity end users with a reasonable fee-charge. But the main problem of setting retail price is how to share and fully circle the electric cost under the circumstance of giving consideration to the real level of usage. However, as limited by the institution, China has carried out the fixed pattern to sale price for a long time and the fees of transmission and distribution are strictly controlled by nation and provinces. Therefore, the cost share method and practical use are not noticed. Also because the fixed cost holds the very great proportion in the electric cost, hence the study of speeding up domestic electric power market reform with the help of fixed cost share is significant in theory. and practice.Focusing on the above problem, this paper gives a review of allocation methods based on the marginal cost and integrated accounting cost and compare and discuss the advantages and disadvantages, while contrasting the differences of financial cost and pricing, and general allocation formula; Combining with the particularity of power grid enterprises, fixed cost allocation problem was pointed out, and the improved model of fixed cost allocation under the electricity load rate was putforward at same times. On account of our current electric power market and theoretical background, the paper studies the marginal cost upon the load rate, which can effectively avoid the cross-subsidization and in favor of the fair share of system load capacity, at the same time it lay a foundation of determining the acceptable price. In addition, combined with the real data of A grid corporate, it gives the application notes of this method and then verify the rationality of the model and algorithm.
