摘要：

A New Decomposition-Coordination (DC) methodology for solving the long-term optimal scheduling of interconnected multi-reservoir power systems with stochastic river inflows is presented. The problem (with M reservoirs and N regional power systems) is composed of M hydro and N thermal subproblems. The optimization of the individual hydro subproblem can be solved by a 2-state Stochastic Dynamic Programming (SDP) taking into account the stochasticity and time series correlation of the river inflows. The thermal and hydro coordination is accomplished by successively updating dual variables so that the total average hydro and thermal generations meet the predicted system load demands. A computer program has been developed and tested for the Central China and East China Interconnected Power System with upto 9 reservoirs. Numerical result shows the effectiveness of the proposed method as compared with existing methods. © 1990 IEEE
