Abstract :
This paper presents a new voltage tracking controller for LCL-filter connected distributed power converters. The control system incorporates droop control laws using a second order low-pass filter and a high-bandwidth numerical differentiation method. Simulated spectral analyses show a comparable output impedance and an enhanced command tracking bandwidth relative to industry standard regulators.
