The questionable generation of solar power, wind sources and load demand makes AC microgrids increasingly complicated and presents the frequency oscillations. It is profoundly expected to build up power balance among generation and load demand by planning a suitable controller for frequency oscillations. Thus, in this research article, a novel approach is proposed by considering a modified equilibrium optimization algorithm (MEO) Algorithm-based Interval Type-2 Fuzzy proportional integral derivative Controller (IT2FPID) structure for the frequency control of an AC microgrid. The performance of the modified algorithm is tested by comparing it with the standard EO algorithm by considering various standard benchmark test functions. Further, the genuine utilization of the MEO algorithm is tried by planning an IT2FPID controller for frequency regulation of an AC microgrid. The supremacy of the MEO-based IT2FPID controller is introduced by comparing its outcomes with MEO-based Type-1 FPID, conventional PID, EO-based PID controller and observed that the proposed MEO-based IT2FPID controller is more effective.

可疑的太阳能，风源和负荷需求的产生使交流微电网变得越来越复杂，并呈现出频率振荡。强烈期望通过为频率振荡设计合适的控制器来在发电和负载需求之间建立功率平衡。因此，在这篇研究文章中，通过考虑基于改进平衡优化算法（MEO）的间隔2型模糊比例积分微分控制器（IT2FPID）结构用于交流微电网的频率控制，提出了一种新方法。通过考虑各种标准基准测试功能，将改进算法与标准EO算法进行比较，以测试改进算法的性能。更多，通过计划IT2FPID控制器来调节AC微电网的频率，可以尝试真正利用MEO算法。通过将其结果与基于MEO的Type-1 FPID，常规PID，基于EO的PID控制器进行比较，介绍了基于MEO的IT2FPID控制器的优越性，并观察到所提出的基于MEO的IT2FPID控制器更为有效。
