Droop Control Strategy Design of Microgrid Based on Virtual Frequency
摘要
Abstract
According to the resistive characteristic of low-voltage microgrid, decoupling control of active power and reactive power is achieved. Voltage droop control method was used in active power distribution, and phase angle droop control method was used in reactive power distribution. On the basis of analysis of droop control model, since the phase angle of distributed generator is determined by two parts:frequency and the initial phase angle, virtual frequency which is proposed in this paper is applied to the voltage/phase-angle droop control strategy. In the improved control strategy, the change of virtual frequency converts into the change of the initial phase angle. Feasibility and effectiveness of the strategy is confirmed by Matlab simulation.关键词
