RODRIGUES, L. G. L. (2003). The Study of E/etric-Energetic Coupling in lhe ShoriShortest Term Operation Planning Using FPOCA. M.Sc. Dissertation Escola de Engenharia de São Carlos, Universidade de São Paulo, São Carlos, 2003. This work brings a begimúng study of the electric-energetic coupling in the shOiishortest term operation planning using Optimal Power Flow in Alternate Current (OPF AC) aiming to inquire possible mismatches between the energetic planning and the eletric planning. It is made an analysis of the electrical aspects influence in the short tenn energetic plamúng using OPF AC together with the minimization o f generation cost and the transmission losses. The generation cost minimization is made for the hidrothermal system optimization using a Hydrothennal System Optimization Program (POSH) based on a convex simplex algorithm and the application of the network flow theory, while the transmission losses mininúzation is made using an OPF AC based on the Dual-Newton method. These tools allow to analyze the necessity of adjustments to make compatible the energetic optimization and the electric optimization of the power system, and to search an "optimal" planning that attends both the energetic planning and electric planning. Like this, the electric-energetic interface becomes strongest, therefore the generation goals gotten by the short-term planning, that will be passed to the sh01iest-tenn planning, already includes the effect o f the electric system aspects. These one provide the rnismatches control in the optirnal trajectory of the system and it contributes to improve the global optimization of power system operation planning. The analyzed system is the 440 kV Equivalent System of CESP (Energetic Company o f São Paulo), with 53 bus, being 7 generation bus, 85 transmission I ines and 48 transformers.
