Operating rules of large-scale multi-reservoir system

In this paper,all the reservoirs are regarded as an equivalent one in form of energy based on an idea of large-scale system aggregation-decomposition.We can obtain an operating function through multi-factors stepwise regression analysis and establish an operating function model of the equivalent reservoir by analyzing on the physics and statistics of the energy factors.We can also establish an output allocation model with a target of maximum storage at the end of period considered,and determine the allocation output to each hydropower station by general decision-making in each period with the operating function obtained.The operating function can also be used to guide operation simulation of long-term runoff series,with consideration of the constraints by hydroelectric powers and the hydraulic inter-connections and comprehensive utilization of all the hydropower stations.Results show that the operating function provides a new way for operation simulation.
