结合有限集模型预测的改进下垂功率均分策略
Improved droop power sharing strategy combined with finite set model prediction
摘要
Abstract
In the low-voltage microgrid,the active power distribution of parallel inverters is uneven due to the mismatch of line impedance parameters,and there are multiple control variables in the cost function of finite set model predictive control,so it is difficult to design the weight coefficient.An improved droop control strategy combined with finite set model prediction is proposed.Firstly,by improving the traditional droop control,the accurate distribution of active power is realized.Secondly,the voltage recovery mechanism is added to compensate the voltage drop caused by the load mutation.Then,combined with the finite set model predictive control,the dynamic response speed of the system is improved,and the voltage and current serial evaluation is used in the cost function to eliminate the weight coefficient configuration.Finally,the simulation and experimental results show that the proposed strategy can realize the accurate distribution of active power,compensate the voltage drop,and realize the stable operation of the inverter.关键词
