dc.descriptionThis paper presents a convex formulation for optimal power flow (OPF) in both radial and meshed grids. A semidefinite programming (SDP) approximation transforms the quadratic non-convex model into a relaxed convex quadratic model, which can be more efficiently solved. This model is implemented in MATLAB using the CVX package for convex optimization. The results obtained are compared to the non-linear model of the problem implemented in GAMS and MATPOWER by using four typical systems in specialized literature (two radial and two meshed). SDP approximation demonstrated to provide accurate solutions that are close to an optimal solution of the problem in shorter computational times. Such solutions are applicable to real-time operation and control problems.en-US
dc.descriptionEste artículo presenta una formulación convexa para el problema de flujo de potencia óptimo (Optimal Power Flow-OPF) en sistemas de potencia radiales y enmallados, a través de un modelo matemático basado en programación semidefinida (Semidefinite Programming-SDP), el cual trasforma el modelo cuadrático no convexo del OPF en un modelo convexo relajado, que puede ser solucionado de forma mucho más eficiente. El modelo es implementado en MATLAB usando el paquete de optimización convexa CVX. Los resultados obtenidos son comparados con el modelo no lineal del problema implementado en GAMS y MATPOWER usando cuatro sistemas típicos de la literatura especializada, dos de tipo radial y dos enmallado. Las soluciones encontradas por esta aproximación convexa, son muy cercanas a las respuestas presentadas en la literatura especializada para el modelo no lineal. Este tipo de aproximación permite obtener soluciones de muy buena calidad, muy cercanas a la solución óptima del problema en tiempos computacionales menores y susceptibles de aplicarse en problemas de operación y control en tiempo real.es-ES
