Linkage price for power generation companies and electrolytic aluminum enterprises is analyzed, so as to achieve a tripartite win-win of power plants, users and power grids under the circumstances of the direct-power-purchasing of large consumer. Seen the electricity energy as the commodity and the power corporation as modern enterprise, with the basic rule of market economy, the calculation method of electric were considered from the point of business operations. In order to determine the proportional coefficient of linkage of aluminum price to electricity price, this paper focused on linkage price and proposed an optimization model, Meanwhile, the optimized ratio coefficients is obtained by solving this model on the discussion of the forecast of electrolytic aluminum price, the demand curve and many other questions. Finally, an analysis demonstrated in this paper proved that the determination of the ratio coefficient of linkage price, not only has important research value in theory, but also has a great feasibility and practicality. |
