A model ofadmission of large consumers direct-purchasing based on Pareto optimal theory

In China, the work of large consumers direct-purchasing undertakes the tasks of optimizing the allocation of electricity resources, speeding up industrial restructuring, enhancing the regional overall economic competitiveness and promoting harmonious and sustainable development of China's economy, environment and electric power industry. Considering the actual status that the total amount opened for direct purchasing electricity in China's present market is certain, based on the admission standards of large consumers direct-purchasing, and applying Pareto optimal distribution theory, this paper establishes series model of large consumers direct-purchasing. With some data of consumers' information of power-supply enterprises from some urban districts in China, this paper finally proves this model's effectiveness and practicability through measurement and calculation.
