Optimum short-term hydrothermal scheduling with spinning reserve through network flows
Rights accessOpen Access
Optimizing the thermal production of electricity in the short term in an integrated power system when a thermal unit commitment has been decided means coordinating hydro and thermal generation in order to obtain the minimum thermal generation costs over the time period under study. Fundamental constraints to be satisfied are the covering of each hourly load and satisfaction of spinning reserve requirements and transmission capacity limits. A nonlinear network flow model with linear side constraints with no decomposition into hydro and thermal subproblems was usedto solve and thermal scheduling. Hydrogeneration is linearized with respect to network variables and novel thermal generation and transmission network is introduced. Computational results are reported.
