Sparse LMS control algorithm for Fuel Cell based SAPF

Nowadays, modification and hybridization of the Custom Power Device (CPD) topology are occurring massively to provide the better power quality service in the distribution system. The selection of a suitable adaptive control algorithm for such CPD is also a tough job for the researchers due to the complexity of the power system. In this paper, the Sparse Least Mean Square (SLMS)control algorithm is implemented in a three-phase Proton Exchange Membrane Fuel Cell (PEMFC) based Shunt Active Power Filter (SAPF) to mitigate the power quality problems. Particularly, harmonic mitigation of source current, voltage regulation and power factor of the system are attained successfully. The performance of this suggested SLMS algorithm affords a balanced and almost harmonic-free supply current even under fault conditions. The reference source currents are generated followed by extracting the weighted values of fundamental active and reactive components of harmonic rich load current. The intention is to maintain the DC-link voltage of the SAPF by generating appropriate switching signals. The simulation has been performed in the MATLAB environment.
