Procedimiento alternativo para la inclusión de límites de potencia reactiva en el flujo de cargas

Abstract

El objeto del presente proyecto consiste en desarrollar una serie de algoritmos alternativos a los actuales para la inclusión de los límites de potencia reactiva en los flujos de cargas. A diferencia de los métodos tradicionales implementados en los softwares comerciales, que requieren cambiar el tipo de nudo (de PV a PQ) cuando un generador alcanza sus límites de potencia reactiva, lo cual implica alterar la estructura del sistema matricial, su dimensión y la necesidad de reordenamientos y nuevas factorizaciones en cada iteración, el método propuesto mantiene fija la estructura del problema a lo largo del proceso iterativo. La metodología se inspira conceptualmente en el método desacoplado rápido (FDLF), pero aplicando lógica inversa. En lugar de calcular las variaciones de tensión (Δ𝑉) a partir de los excesos de potencia reactiva mediante sensibilidades, aquí se parte de desvíos de tensión respecto a su valor especificado para calcular las correcciones necesarias en la generación de potencia reactiva. Esto permite tratar inicialmente todos los nudos como PQ y ajustar iterativamente sus valores de 𝑄 inyectada o absorbida. De ahí que este método alterativo mantenga fija su estructura durante el proceso. Además, se observa que este tipo de formulación puede evitar inconsistencias derivadas de los métodos tradicionales, donde los nudos que alcanzan límites de potencia reactiva no recuperan su estatus de nudos de generación, aunque vuelvan a estar dentro de rango más adelante, lo cual puede influir en los resultados finales.

This project proposes alternative algorithms for incorporating reactive power limits in load flow analysis while preserving the mathematical structure of the problem. Unlike conventional approaches used in commercial software, which require dynamically changing bus types (from PV to PQ) when generators reach reactive power limits, and consequently lead to matrix restructuring, resizing, and refactorization at each iteration, the proposed method maintains a fixed system formulation throughout the entire process. The methodology is conceptually inspired by the Fast Decoupled Load Flow (FDLF) method, but applied in reverse. Instead of adjusting voltages based on reactive power mismatches using sensitivities, the approach uses voltage deviations from specified values to calculate the necessary reactive power corrections. This allows all buses to be initially treated as PQ, simplifying the numerical treatment. In addition, the method helps avoid inconsistencies observed in conventional techniques, where buses that exceed their reactive limits do not revert to PV status even when their values return within acceptable bounds, which can affect the final load flow results.
