Abstract :
A method is presented for short-term production scheduling in a hydro system. The solution technique is based on iterative network linear programming and heuristic techniques. The method handles security constraints due to single branch and specified multiple contingencies. The postcontingency rescheduling capabilities are modeled explicitly in a DC optimal load flow. Using the rescheduling capabilities increases the transmission network utilization
