“…El problema de FPO busca optimizar una función específica, satisfaciendo restricciones que son regidas particularidades operacionales y físicas de la red eléctrica. El problema de FPO es un problema cuyos modelos matemáticos utilizados envuelven dificultades como: no linealidad y no convexidad, millares de restricciones, variables discretas y/o enteras, lo que ocasiona un problema de difícil solución, tornándose en un tema abordado por varios investigadores [13,14], dado que su aplicación puede abarcar temas que van desde el planeamiento hasta la operación de los sistemas eléctricos [15,16].…”

This paper presents an analysis methodology for transmission systems with the integration of wind generators type Doubly Fed Induction Generator (DFIG). The methodology used two stages: in the first one scheme for DFIG is realized to control the active and reactive powers, in the second phase using an Optimal Power Flow (FPO), with minimization of active losses, as the objective function to analyze system performance. The FPO problem was simulated with the tool AMPL (A Mathematical Programming Language), using the solver KNITRO. Simulations performed with a standard IEEE 14 barring "modified" clearly shows the benefits of using the associated generator control with FPO.

“…In Brazil, electric energy losses represent 17% of the total energy generated by the power system, and the technical losses in the transmission system are between 4% and 8% of the total active power generated . In Brazil, with the advent of smart meters in accordance with the Administrative Rules 440 and 223 of the Brazilian Electric Power Agency (in Portuguese, Agência Nacional de Energia Elétrica—ANEEL), a flattening of the load curve by limited consumption during peak times is expected.…”

SUMMARY Sensitivity analysis oriented by optimal power flow problem is applied in this work to estimate nodal technical losses in power transmission networks in a smart grid environment. This approach aims to efficiently provide active power loss indices as a result of load variations at each single load bus connected to the system. Unlike the power flow algorithm, this technique does not require an iterative process to find the solution, which results in a faster methodology with high accuracy and reduced computational cost, even when considering all the characteristics of the system. The methodology starts from a known optimal solution obtained by optimal power flow, considered as the base case. From the base case solution, new solutions can be evaluated by sensitivity analysis when system load bus perturbations occur. Tests were carried out on the IEEE 14 and 118 bus systems in order to evaluate the proposed technique performance. Copyright © 2012 John Wiley & Sons, Ltd.
