Abstract

This study proposes an incorporated strategy based on energy storage technologies like aggregated electric vehicles (AEVs) with frequency regulation (FR) to enhance the frequency stabilization during high renewable sources (RSs) penetration. Furthermore, an innovative cascaded controller is used in the FR loop, and the considered AEVs in isolated multi-sources microgrid system. The proposed control structure is based on using two terms, the first term is the fractional order proportional-integral (FOPI), and the second cascaded term is a tilt derivative with filter (TDF) to form the cascaded (FOPI-TDF) controller. Furthermore, the gains of the proposed controller are well optimized utilizing skill optimization technique (SOT). The effectiveness of the proposed FOPI-TDF controller is validated by comparing its performance with PID, tilt-integral-derivative (TID) controllers. Additionally, the study investigates the impact AEVs in stabilizing the system frequency under randomly generated power from RSs and load perturbation.

考虑通信延迟的电动汽车利用级联控制器改进微电网频率调节

本研究提出了一种基于聚合电动汽车(aev)和频率调节(FR)等储能技术的整合策略，以增强高可再生能源(RSs)渗透期间的频率稳定性。此外，在隔离型多源微电网系统中，采用了一种新颖的级联控制器，并考虑了多源隔离型微电网系统中的aev。所提出的控制结构基于使用两项，第一项是分数阶比例积分(FOPI)，第二项是带滤波器的倾斜导数(TDF)，形成级联(FOPI-TDF)控制器。此外，利用技能优化技术(SOT)对所提控制器的增益进行了优化。通过与PID、倾斜积分导数(TID)控制器的性能比较，验证了所提出的FOPI-TDF控制器的有效性。此外，研究了在随机产生的RSs功率和负载扰动下，aev对稳定系统频率的影响。
