Abstract
Many optimization methods for power production planning in a hydro-thermal power system have been applied. The methods vary from heuristic to purely mathematical methods. Most present methods for solving the coordination problem are based on decomposition where the overall problem solution is obtained by coordinating between the solution of subproblems.
In this paper the problem is decomposed to a master problem and two sub-problems: thermal and hydro. Power demand, which acts as a coordinator, is divided in the master problem to subproblems using heuristic approach. Thermal subproblem is solved with MILP. Hydro subproblem is solved using optimal closed loop control. The problem is solved iteratively so that only a few successive iterations are needed. We demonstrate the algorithm with reference to a simple production system.
