Power system wideband oscillation estimation, localization, and mitigation

With the development of energy structure power system, characterization observed oscillation in system has steadily evolved. increasingly high penetration distributed sources and electronic devices, such as photovoltaic, wind charging pile, basic mechanism, frequency ranges propagation would become more dynamic complex. Therefore, traditional parameter estimation, well suppression methods also suffer from oscillations. To this end, paper first investigates typical events caused by Next, model estimation method including model-based data-driven based is discussed. The benefits difficulties various estimate techniques are highlighted. Under context, validity limitations current stability summarized. Furthermore, different damping mitigation measures compared, major adaptability listed for specific application scenarios. Conclusions drawn, wideband becomes future research objective where work presented at end paper.
