Series-shunt power active filter for high penetration of embedded production one dynamic approach

The increase of the embedded production brings problems of energy quality which must be solved. Several literatures show that these problems can be reduced with the installation of Unified Power Quality Conditioners (UPQC). In this paper in alternative to the Theory of Instantaneous Power (p-q) and to the Direct Quadrature Zero transformation (dq0), one novel approach to the UPQC is proposed. That is inspired on the Methods of Qualitative Theory in Nonlinear Dynamics along with the classic control methods. Its architecture allows a strongly reducing of the harmonics in both currents and voltages in balanced or unbalanced systems with linear or nonlinear loads. Moreover, in that situations the transients are strongly mitigated too. The large increase in the power quality achieved with these devices allows a high level of embedded electrical energy production.
