This study proposes a time domain methodology for harmonic state estimation (HSE) in power systems. The proposed methodology is formulated to analyse the unbalanced operation of three-phase power systems including non-linear loads. It takes into account the optimal number of measuring devices and exploits the property of half-wave symmetry in voltage and current waveforms to significantly reduce the...
Power quality simulation is required to provide an evaluation of the adverse phenomena such as transients, harmonics, and voltage sags in a power system, among others. This paper details a methodology to assess adverse power quality effects. In this methodology, the power system is modeled in the continuous-time by an ordinary differential equations set. The equations set are solved through a numerical...
This paper presents a review of harmonics in offshore wind farm systems. The aim is to gather information of mathematical models for harmonic analysis in wind farms and algorithms to configure offshore network interconnections. A thorough literature review is presented that may help to develop a solution in MatLab or LabView for harmonic analysis in offshore wind farms with multi-technology components.
This paper presents an algorithm, based on the simplex method, to reconfigure distribution systems minimizing harmonics and power losses. The algorithm is implemented in LabView and calculates the power flow and the harmonics flow, then uses the simplex method to obtain the maximum current flow, in a second stage the data is saved for each configuration, and finally with all the data, the algorithm...
