  • This is the first time that a rigorous and complete analysis of the dynamics of the open-loop AC/DC converters has been carried out to examine the power factor correction. Previous researches missed an open-loop formal study. For this purpose, a relationship among inductance, capacitance, and parasitic resistances (which were ignored in most previous studies) is established using the singular perturbation technique.
  • It is formally proven in this study that the control objectives (i.e. Power Factor Correction and DC voltage regulation) are successfully accomplished by a systematic theoretical analysis focusing, for the first time, on new techniques such as three-time scale singular perturbation and averaging theory. Previous researches lacked a closed-loop formal analysis.
  • In contrast to many studies that rely on traditional methods (sliding mode, backstepping, passivity, etc.), this paper presents a new control approach based on the multi-time scale singular perturbation technique for performance analysis and control. This technique has recently attracted a lot of interest thanks to the multi-time scale nature of static power converters.

Abstract (2103 Views) | Full-Text (PDF) (1102 Downloads)   |   Highlights
  • The impact of symmetric and asymmetric RES development policies on the potential of exercising market power within MEMs is investigated. Something that to the best of our knowledge has not been investigated in previous studies.
  • The effect of increasing the integration of the markets on market competitiveness in the presence of different policies on RES penetration within MEMs is analyzed.
  • A stochastic multi-objective decomposition method is used in the agent-based simulation framework to analyze the power plants' behavior and markets. The use of a multi-master problem in the agent-based simulation has not yet been performed in the power system.
