Susquehanna River Short-Range Hydrothermal Co-ordination

A computer program has been prepared to perform short-range co-ordination studies of two Susquehanna River hydroelectric plants with the thermal generation in the Pennsylvania-New Jersey-Maryland Interconnection System. Dynamic programming with successive approximations was used to form a computing method which would minimize thermal fuel costs. Hydroelectric plant-head variations were accurately represented in the program, as were the practical operating limitations upon plant discharges and reservoir withdrawals from storage.
