基于PSO的逆变器接口电源输出控制器的优化方法

PSO-based optimization method of output-controller for inverter interface power supply

随着我国电力需求的持续增加,微电网不断地接入电力系统。微电网将分布式电源、负荷、储能装置、能量变换设施和控制装置集成一个整体进行综合控制。由于其规模的不断扩大,其运行难度也在不断增加,难以满足用户越来越高的安全性和可靠性要求。提出了一种基于PSO算法的逆变器接口分布式电源控制方法,通过优化逆变器输出控制器参数,能够有效抑制存在于微电网中的电压、频率、操作模式转换等干扰。仿真实验验证了该智能控制方法的正确性与有效性。

With the increasing demand of electricity,more and more microgrids access to power systems. In microgrid, distributed power,load,energy storage facilities,energy conversion facilities and control devices are integrated into an integral whole to make comprehensive control. Because its size is expanding and the operation difficulty is increasing,it is difficult to meet users′ increasing requirements of high safety and reliability. A PSO algorithm based control method for the distributed power supply of inverter interface is proposed in this paper. The interference of voltage,frequency,operating mode conversion existing in microgrid can be efficiently suppressed by optimizing the parameters of the inverter outputcontroller. The simulation results show the correctness and effectiveness of the intelligent control method.
