Abstract

A micro-source inverter which is connected with the microgrid is studied in this paper, and it has the function of harmonic compensation and power supply. Considering the output power of the generating unit (GU) and the load are unsteady, an improved deadbeat control algorithm (DCA) based on a novel hybrid prediction strategy (HPS) is proposed. The improved DCA can solve the delay problem of the conventional deadbeat control and improve the precision of the whole control system. Then the simulation shows that the improved DCA can be correctly and effectively applied into the control of the micro-source inverter.
