New Model Predictive & Algorithm DPC based Shunt Active Power Filters (SAPFs)

The proliferated use of the non-linear loads in the household and industries are distorting the power quality of the grid significantly. The use of filters brings about an improvement in the of the grid power quality. The active filters have been preferred from the passive filters as they are free from resonance, tuning difficulty, and need for the parameter change with changing load. The control techniques like the model predictive and the algorithm based direct power control are well-known control methods for the control of active front end rectifiers This paper proposes the use of these techniques for the control of shunt active power filters. Computer simulation models for the proposed methods are built using MATLAB/Simulink environment and a comparative analysis is presented with respect to the pre-existing switching table based DPC controlled shunt active power filter.
