论文摘要
本文提出了一种新的负载频率控制（LFC）方法，该方法是在两个面积热力系统中系数图法（CDM）的最佳结构上提出的。作为现实分析的一部分，已经考虑了与州长死率（GDB）和发电率约束（GRC）有关的非线性。在本文中，将混合CDM方法与其数学方程式的优化相结合，以实现创新控制器。此外，一种称为水循环算法（WCA）的新型元启发式优化技术用于确定CDM控制器的最佳系数。为了证明所提出的方案的有效性，测试了非线性动力系统动态参数中的各种不确定性。此外，从经典的积分，单独的CDM，优化的模糊，优化的PID和建议的控制器获得的结果之间进行了比较研究。在这种改善控制的新方法中，代数支持提供了强大而响应的控制器，可以提供快速，稳定的动态响应，并有效地克服了功率系统参数中非线性和不确定性的有害影响。
This paper proposes a novel load frequency control (LFC) approach formulated on an optimal structure of the coefficient diagram method (CDM) in a two-area thermal power system. As part of a realistic analysis, nonlinearities related to governor dead band (GDB) and generation rate constraint (GRC) have been considered. In this article, a hybrid CDM method is combined with the optimization of its mathematical equations to achieve an innovative controller. Furthermore, a new metaheuristic optimization technique called the water cycle algorithm (WCA) is used to determine the optimal coefficients of the CDM controller. For the purpose of demonstrating the validity of the proposed scheme, a wide range of uncertainties in the dynamic parameters of a nonlinear power system were tested. In addition, a comparative study is presented between the results obtained from a classical integral, CDM alone, optimized Fuzzy, optimized PID, and the suggested controller. In this new approach to improved control, algebraic support provides a robust and responsive controller that can provide fast and stable dynamic responses and effectively overcome the detrimental effects of nonlinearities and uncertainties in the parameters of the power system.
