Abstract

The islanded mode is one of the connection modes of the grid distributed generation resources. In this study, a distributed generation resource is connected to linear and nonlinear loads via a three-phase inverter where a control method needing no current sensors or compensator elements is applied to the distribute generation system in the islanded mode. This control method has two main loops in each phase. The first loop controls the voltage control loops that adjust the three-phase point of common coupling, the amplitude of the non-sinusoidal reference waveform and the near-state pulse width modulation (NSPWM) method. The next loop compensatesthe harmonic compensator loop that calculates the voltage harmonics of the point of common coupling in each phase, and injects them to compensate the non-sinusoidal reference waveforms of each phase. The simulation results in MATLAB/SIMULINK show that this method can generate balanced three-phase sinusoidal voltage with an acceptable total harmonic distortion (THD) at the joint connection point.
