This paper presents the modelling and design steps of a digital proportional multi-resonant controller used in a grid-connected photovoltaic (PV) system. It is shown that the use of only one Proportional-Resonant (PR) compensator, tuned to the system fundamental frequency, may have its...

This paper is deals with the implementation of a software control method for harmonic content evaluation in the dq synchronous rotating reference frame for grid side VSIs (Voltage Source Inverters) used in DPGS (distributed power generation systems) applications. In order to verify the...

This paper is interested in the control of a wind energy conversion system (WECS) based on the doubly fed induction generator (DFIG) under grid fault conditions. A single line to ground fault and a double line to ground fault are tested during the hyper-synchronous operation of the DFIG wind...
