Abstract

Due to the large variety of renewable power sources, power electronics play an important role in energy conversion. Different power converter topologies are used to interface distributed power generation systems (DPGS) with the utility network. Introduction of power electronics for DPGS provide several advantages such as energy optimal operation by employing a control algorithm to extract the maximum available power. In addition, load control, reduced noise, controllable active and reactive power and improved power quality. Using a LCL filter to ensure that high quality power is delivered comes at the expense of degraded stability unless mitigation procedures are followed. In this paper, a stationary frame current control for inverter-based distributed generation (IBDG) with sensorless active damped LCL filter is proposed. The Kalman filter sensorless-based technique not only mitigates the stability problem regarding the resonance of the LCL filter, but it improves the overall stability margins. The concluded assumptions were simulated through Matlab/Simulink and verified experimentally with a laboratory prototype. © 2014 IEEE.
