This study presents the impact of wind power plant components modelling on harmonics propagation and harmonic small-signal stability studies. Different types of cable and transformer modelling techniques are taken into consideration, e.g. state-of-the-art standard models and latest academic developm...

Field solvers are often needed to properly characterize the behavior of grounding structures in a wide frequency range. These solvers provide accurate results but at high computational cost. Design tasks, such as design optimization and sensitivity analysis, require repeated simulations for differen...

This paper presents a new approach to wideband modeling of tower footing grounding impedances. Appropriate representation of transmission tower footing impedances is essential in electromagnetic (EM) transient simulations for proper evaluation of overvoltages and flashovers in the system during fast...
