Power converters have an outstanding potential in micro and smart grid applications that require flexible and fast power control as well as rigid voltage regulation at the point of common coupling. Power converters are required to properly operate under several modes of operation such as grid-tie and micro-grid modes of operations. In addition, the control system should be designed to enable proper load sharing between several units. Several control techniques have been proposed in the literature to address most of the control requirements of the power converters under different operating modes mentioned above. However, references found in the literatures are usually centered on the analysis of the system under only one mode of operation and using a single control strategy. Comprehensive study that combines an in depth analysis of the power converters control under several modes are very scarce in the literature. In this thesis, a detailed survey and analysis of power converter control techniques in Grid-Tie and AC Micro/Smart Grid applications are introduced. This analysis is based on detailed nonlinear time domain simulations as well as average and small signal models for system stability assessment and performance evaluation.
