|Abstract:||In this study, a multilevel-decentralized solution and implementation strategy is developed for the long-term operations planning and the real-time operations of a multi-purpose, multi-reservoir river basin system.
Assuming that the strategical-tactical decisions and the operational decisions are made by distinct managerial echelons, the proposed strategy replaces the large organizational problem by a sequence of subproblems to be solved at different levels of management. More specifically, the general river basin manager first solves an annual planning problem with monthly time steps to determine the optimal end-of-month conditions. He then solves a weekly time step problem for a month to determine the optimal weekly water releases and energy productions. Disaggregating the weekly releases over time, he provides target hourly releases for each reservoir operator. Each operator then solves an hourly time step problem for his reservoir only, to determine an optimal hourly water release schedule for each prupose, and implements the solution.
For the solution of the above monthly, weekly, and the hourly time step problems an augmented Lagrangian type algorithm is developed.
The proposed strategy is implemented using a set of data on the Shasta-Trinity System of the California Central Valley Project. Then, the stability and the sensitivity of the solutions are checked through various parameter alterations. Thus, the applicability of the proposed strategy in the real-world environment is also demonstrated.
