This paper describes a frequency domain approach for evaluating the impact of tower shadow and wind shear effects (TSWS) on tie-line power oscillations. A simplified frequency domain model of an interconnected power system with a wind farm is developed. T... see more

The problem of electromagnetic waves propagation in overhead transmission lines has apparently not been solved in a sound manner yet. While the problem does not have an exact analytical solution when considering the presence of the actual surface of the e... see more

En las plantas de generación distribuidas accionadas por motores reciprocantes es necesario conocer las fluctuaciones de tensión, corriente y potencia para evaluar la calidad de la energía que entregan estos grupos electrógenos y como criterio de diagnóst... see more

Wind power causes fluctuations in power systems and introduces issues concerning system stability and power quality because of the lack of controllability of its discontinuous and intermittent resources. This paper presents a coordinated control strategy ... see more

The existing literature predominantly concentrates on the utilization of the gradient descent algorithm for control systems’ design in power systems for stability enhancement. In this paper, various flavors of the Conjugate Gradient (CG) algorithm have be... see more

La evaluación de los errores en el comportamiento de la frecuencia en condiciones de perturbación de un sistema eléctrico al utilizar modelos concentrados en los cálculos que no tienen en cuenta la existencia de oscilaciones locales e inter áreas de la fr... see more

Solar modules have current and voltage characteristics that are non-linear, so efforts must always be made to work at the maximum power point so that no energy is wasted. The characteristics of the solar module will change depending on the level of radiat... see more

En este artículo, se realiza un estudio de los principales errores que introduce la inducción mutua de secuencia cero en el trabajo de las protecciones de sobrecorriente direccional y distancia de tierra respectivamente (67N y 21N), cuando estas se encuen... see more
