Abstract

Microgrids attain a significant role in electrical power systems due to their practical and economic benefits. A novel application of an adaptive Proportional plus Integral (PI) controller with the purpose of improving the microgrid performance is presented in this paper. The control strategy of the adaptive PI controller is based on Widrow-Hoff adaptation technique. The efficiency of the suggested controller is proved by comparing its outcomes with that obtained by utilizing Flower Pollination algorithm (FPA) which is used to fine tune the PI controller parameters of the inverter based microgrid. The utilized multi-objective optimization problem used by the FPA is created by the Response Surface Methodology (RSM). Simulation results are carried out using PSCAD/EMTDC environment to check the validity of the proposed control strategy. The simulation results are tested under various operating states such as 1) conversion of the system from grid connected to stand alone mode of operation, 2) subjecting the system to three line to ground fault in the autonomous mode, and 3) exposing the system to the load variability in the islanded mode.

微电网性能增强的自适应PI控制策略

微电网因其实际和经济效益在电力系统中发挥着重要作用。本文提出了一种用于改善微电网性能的自适应比例加积分(PI)控制器的新应用。自适应PI控制器的控制策略基于Widrow-Hoff自适应技术。通过将所提控制器与采用授粉算法(FPA)对逆变微电网PI控制器参数进行微调的结果进行比较，证明了所提控制器的有效性。利用响应面法(RSM)建立了FPA所使用的多目标优化问题。在PSCAD/EMTDC环境下进行了仿真，验证了所提控制策略的有效性。仿真结果在多种运行状态下进行了测试，如1)系统从并网模式转换为独立运行模式，2)系统在自主模式下遭受三线接地故障，以及3)系统在孤岛模式下暴露于负载变化。
