Abstract

The integration of Microgrids (MGs) into the mains must be done with consideration of control techniques that ensure the appropriate synchronization and power balance between distributed generators (DGs) and the grid. This paper presents the development of a PQ-control model for the grid connected single-phase and three-phase inverters present in the Distributed Asset Research Testing (DART) facility in Lubbock, Texas. In a grid-tied configuration, the inverters will operate as a current source that inject current into the grid based on the established reference setting of active and reactive power. To achieve this operation, the inverter current must be monitored, and it will be subjected to abc to dq0 transformation (Clarke and Park transformation). In the case of a single-phase inverter, two orthogonal phase variables are required in order to perform the Park transformation (αβ-dq). A phase shift of 90° with respect to the real phase variable is introduced to get the beta component required to complete this transformation. By showing the power characteristics in simulations, the proposed control strategy will be illustrated. The entire work is performed in MATLAB/SIMULINK environment.
