Power Decoupling Control Method for Grid Connected Inverters under Unbalanced Load
摘要
Abstract
In order to solve the problems of poor control accuracy and slow response caused by the coupling effect between active and re-active power of grid connected inverters under unbalanced loads,a power decoupling control method for grid connected inverters under unbalanced loads is proposed.Based on the topology of the grid connected inverter,the power of the grid connected inverter is obtained,and the active and reactive power of the grid connected inverter are decoupled.The power decoupling control of the grid connected in-verter is achieved through a dual closed-loop power controller with proportional coefficients.On this basis,genetic algorithm is used to optimize control parameters and obtain the optimal solution of proportional coefficients,further improving the power decoupling control a-bility of grid connected inverters.The experimental results show that the decoupled control method has a good control effect as the re-sponse power of the grid connected inverter is basically consistent with the given power.The decoupled power fluctuation range is re-duced by 8 kW,and the power control current and power fluctuation are minimized.关键词
