This thesis investigates the active/reactive power control strategies for a grid-connected microgrid to let the photovoltaic (PV) system more flexible in operation and control through power electronics. It is to refer to the voltage level of the microgrid in the Taiwan Institute of Nuclear Energy Research. The grid-connected microgrid is established by the Matlab/Simulink, which includes PV system, smart inverter, battery energy storage system (BESS) and LCL filter. It is connected to the utility through the distributed transformer. Finally, the results present that the PV array is kept at the maximum power point by the maximum power point trakers. The smart Inverter has active/reactive power control function. The BESS stabilizes DC voltage and absorbs or releases the PV power to promote the power generation efficiency of PV and reliability of system. The LCL Filter effectly reduces the total harmonic distortion of current (ITHD).
