Recently, there has been a growing trend of large proliferation of electric vehicles (EVs) due to its various merits like minimum emission of greenhouse gases, high-energy efficiency, less maintenance, cost, and so on. Electric vehicles are now seen as an environment friendly and cost effective alternative to the fuel vehicles. This article presents an effective load frequency control of a multi-area interconnected power system connecting EV fleets along with diversified sources such as Archimedes wave energy conversion (AWEC), geothermal power plant, wind power plant turbine generator, hydro power plant, and thermal power plant. A cascaded controller, combination of tilt integral derivative filter (TIDN) and 1+proportional-integral (1+PI) (ie, TIDN-(1+PI)), has also been proposed in this article as a secondary controller to improve the system performances. The real-time simulation of the considered power system has been effectually executed under different scenarios, using OPAL-RT's digital simulator. The result shows that the proposed TIDN-(1+PI) controller along with EV fleets are capable to significantly minimize the frequency and tie-line power oscillations rapidly and it also provides better dynamic performance of the system as compared to other conventional controllers such as integral, proportional-integral and so on. In addition, variable and irregular AWEC power, load disturbances in all areas, and multiple nonlinearities have been considered to study the effect of EV fleets in the proposed system. Also, stability of the system has been studied by using Eigen value analysis method.

TIDN-(1+PI)级联控制器在电动汽车-阿基米德波浪能-地热-风力发电多区域水热系统LFC中的首次应用

近年来，由于电动汽车（EV）具有温室气体排放量少、能效高、维护少、成本低等诸多优点，其大规模普及的趋势越来越明显。电动汽车现在被视为燃料汽车的环保且具有成本效益的替代品。本文介绍了多区域互连电力系统的有效负载频率控制，该系统将 EV 车队与多种来源（如阿基米德波浪能转换 (AWEC)、地热发电厂、风力发电厂涡轮发电机、水力发电厂和火电）连接起来。植物。一个级联控制器，组合倾斜积分微分滤波器（TIDN）和1+比例积分（1+PI）（即TIDN-（1+PI）），本文还提出了作为辅助控制器来提高系统性能的建议。所考虑的电力系统的实时仿真已在不同场景下有效执行，使用 OPAL-RT 的数字仿真器。结果表明，所提出的 TIDN-(1+PI) 控制器与 EV 车队一起能够显着降低频率和联络线功率振荡，并且与其他传统控制器相比，它还提供了更好的系统动态性能，例如积分、比例积分等。此外，还考虑了可变和不规则的 AWEC 功率、所有区域的负载扰动和多重非线性，以研究 EV 车队在拟议系统中的影响。同时，利用特征值分析方法研究了系统的稳定性。
