Analysis on Electricity Pricing Mechanism for Cascade Hydropower Stations in China
Applied Mechanics and Materials, 2011For the large cascaded hydropower stations, an electricity pricing mechanism of cascade hydropower stations on large basins is proposed. The main idea is that the electricity generated by different hydropower stations on the same river can be sold to the Grid Corporation with the same price.
