Abstract
In low-voltage microgrid, active power v.s voltage (P-V) and active power v.s frequency (P-f) droop control methods are widely adopted among inverters. Both the two droop control methods show their respective advantages in the control of voltage or frequency in terms of different load conditions. In order to reduce the deviation between output voltage and rated value, this paper proposed a dual mode droop control method, in which the inverter can work with either P-V orP-fdroop control according to the load conditions and update realtime. Changing voltage and frequency obtained by droop control to switch control method directly. This control mode is easy to achieve, and it can reduce the offset between output voltage and the rated value, further to optimize system performance. Simulation and experiment results validate the effectiveness and feasibility of the proposed method.关键词
