This paper proposes an optimization algorithm
based on linear matrix inequalities (LMIs) to be implemented
in a shunt active power filter (SAPF) enabling it
to perform a selective compensation of nonefficient powers
when the rated power of the SAPF is limited. The system
uses the IEEE Standard 1459 to identify the different
power terms (active, reactive, unbalance, and harmonics)
demanded by local loads in a three-phase four-wire system.
Then, the algorithm solves a quadratically constrained
quadratic program by means of an LMI formulation and
calculates the optimal reference currents that allow the
SAPF to cancel a selection of the previously identified
nonefficient power terms. For this selection, the algorithm
presents different weighting coefficients in the cost index
to be optimized. These coefficients assign a relative
importance to each different nonefficient power term,
giving priority to some over the others. Moreover, the
optimization performed in this work to calculate the reference
currents considers that the SAPF presents a power
limitation. Finally, the reference currents’ tracking has been
implemented using a proportional feedforward controller
which assures a constant commutation frequency of the
SAPF. Exp [-]
