摘要：

This paper studies a novel robust voltage regulator to manipulate a boost direct current/alternating current (DC/AC) inverter in grid-connected power systems. It is assumed the AC side feeds unknown loads and the characteristics of the network line and the grid have uncertainties. Based on the active and reactive powers of the connected grid, the references for the currents of the gird are designed. Also, to simplify the controller design procedure the abc to dq0 change of coordinate is used. Moreover, to reduce the CO2 emissions of the conventional diesel motors/generators fuel cells are deployed as the main source. However, the challenge of stabilizing the voltages and currents of the AC MG is handled by a robust it-synthesis based controller. To evaluate the performance of the designed controller, several scenarios with constant and time-varying references and different uncertainties are performed.
