Recent improvements in renewable energy sources (RESs) and their extensive use in the power industry have created significant issues for their operation, security, and management. Due to the ongoing reduction of power system inertia, maintaining operational frequency at its nominal value and minimizing tie-line power variations constitute essential variables for these improvements. A novel improved frequency stabilization approach based on modified fractional order tilt controller is presented for interconnected diverse power systems with integration of sea wave energy, photovoltaic, wind, energy storage system and biodiesel generator. The fractional order tilt integral double derivative (FOTIDD) is a novel controller that is developed to address the frequency stabilization problems of a hybrid power structure that is integrated with sources of clean energy and devices for storing energy. A recent optimization algorithm inspired by human behavior called mother optimization algorithm (MOA) is applied to adjust the coefficient of the proposed cascaded controller. The FOTIDD controller was compared with other control methods in terms of its transient performance, in order to determine its effectiveness. Further, the mother optimization algorithm results are compared with those of sine cosine algorithm (SCA), fox optimization algorithm (FOA), and grey wolf optimization (GWO). FOTIDD controller was found to be more effective than PID controller in respect of reducing overshoot (Osh) by 79.31%, 83.78% and 67.99%, improving time settlement by 33.22%, 29.87%, and 22.45% and reducing undershoot (Ush) by 79.13%, 89.34%, and 86.90% for the (∆F1), (∆F2), and (∆Ptie), respectively.
可再生能源（RESs）的近期改进及其在电力行业的广泛应用给其运行、安全和管理带来了重大问题。由于电力系统惯性的持续降低，将运行频率维持在标称值并使联络线功率变化最小化成为这些改进的关键变量。针对集成了海浪能、光伏、风能、储能系统和生物柴油发电机的互联异构电力系统，提出了一种基于改进分数阶倾斜控制器的新型频率稳定方法。分数阶倾斜积分双导数（FOTIDD）是一种新型控制器，旨在解决与清洁能源和储能装置集成的混合电力结构的频率稳定问题。一种受人类行为启发的最新优化算法——母优化算法（MOA）被用于调整所提出的级联控制器的系数。为了确定其有效性，将FOTIDD控制器与其他控制方法在暂态性能方面进行了比较。此外，还将母优化算法的结果与正弦余弦算法（SCA）、狐狸优化算法（FOA）和灰狼优化算法（GWO）的结果进行了比较。结果发现，对于（∆F1）、（∆F2）和（∆Ptie），FOTIDD控制器在减少超调量（Osh）方面分别比PID控制器有效79.31%、83.78%和67.99%，在改善调节时间方面分别提高33.22%、29.87%和22.45%，在减少欠调量（Ush）方面分别降低79.13%、89.34%和86.90%。
