Active and Reactive Power Control based on an Inner Predictive Voltage Control Loop for AC generation systems with Direct Matrix Converter

Abstract

In order to satisfied the growing electrical energy demand around the world, renewable energy generation systems under distributed generation frame emerges as a plausible solution. In this context wind and micro-hydro generation systems consist of renewable AC sources that need efficient and totally controlled power conversion stages. In this work a novel active and reactive power control strategy based on two cascade control loops using a combination of classical PR controller and Model Based Predictive Voltage Control strategy for AC generation systems are presented. The performance of the system are analysed regarding tracking of reference and THD with satisfying transient results and THD lower than 1 % in the injected current widely accomplishing with international standards.

Predictive Control Applied to Matrix Converters: A Systematic Literature Review

“…Numerous papers have reported successfully implemented predictive voltage control, both in its basic form [117,118] and combined with other behaviors to achieve reactive power minimization [119][120][121][122][123], CMV reduction, switching loss reduction [124] and imposed input current control [125,126]. Figure 12 shows an example for the PVC.…”

Reactive Power Control Using a Model-Based Predictive Control Strategy Applied to an Indirect Matrix Converter

“…Este es el caso del control predictivo basado en modelo (MPC) [6], que se basa en el modelo dinámico del sistema para poder anticipar el comportamiento futuro de las variables de control en un horizonte de tiempo predefinido y selecciona la acción óptima teniendo en cuenta la minimización de una función de costo [7]. Esta estructura se caracteriza porque sus conceptos son muy intuitivos y fáciles de entender, se puede aplicar a una amplia variedad de sistemas, puede involucrar múltiples sistemas, compensación de tiempo muerto y restricciones no lineales, lo que resulta en un controlador fácil de implementar, posibilidad de modificaciones y extensiones para aplicaciones específicas, entre otras [8], [9], [10].…”
