A State estimation approach to harmonic polluting load characterization in distribution systems

This paper develops a weighted least-squares methodology for the estimation of relevant parameters characterizing harmonic polluting industrial loads through a set of measurements acquired at the point of common coupling. The proposed method is capable of obtaining an accurate load model in the absence of detailed information about its internal structure and composition.

Reactive power compensation strategies for wind generation in distribution systems: a power quality approach

This paper studies the impact on the voltage profile of wind energy based generators connected to distribution power systems. Voltage fluctuations arise in distribution levels including noncontrollable primary energy sources because of their corresponding active power injection variations. A number of reactive power strategies have been analysed and compared focusing on the voltage fluctuation minimisation. A distribution network with real wind generation data has been used as a benchmark system to establish the results. Finally, once the reactive power profile is deduced using one of the proposed strategies, a Static Var Compensator is designed in order to show the viability of the adopted reactive power compensation scheme.
