Improved Active Power Filter Performance for Renewable Power Generation Systems

Runali R. Neralkar, V. P. Dhote

Abstract


An active power filter implemented with a four-leg voltagesource
inverter using a predictive control scheme is presented.
The use of a four-leg voltage-source inverter allows the
compensation of current harmonic components, as well as
unbalanced current generated by single-phase nonlinear loads.
A detailed yet simple mathematical model of the active power
filter, including the effect of the equivalent power system
impedance, is derived and used to design the predictive
control algorithm. This proposed system is placed in a wind
and pv based power generation system. A Fuzzy logic
controller is used in the control block to generate accurate
control signals to the inverter circuit. The compensation
performance of the proposed active power filter and the
associated control scheme under steady state and transient
operating conditions is demonstrated through simulations and
experimental results.
