Abstract

AbstractDuring the last decade, the electrical power system has experienced several changes raised by increasing privatization and the newly deregulation policy. Further, the load–frequency control (LFC) job becomes more challenging due to the integration of non-conventional energy resources such as nuclear, wind, solar, and fuel into the power system. If the demand of consumers varies, then the voltage along with the frequency of the multiple area interconnected power system also changes. Therefore, these changes must be kept within a certain range to supply better quality of electricity to the consumers. The study in this article is focused upon the Load–Frequency Control (LFC) of a double area deregulated power system along with multiple generation sources using Tilted-Integral-Derivative Controller (TIDC) with 2DOF. LFC is the mechanism by which the power system tries to restore its nominal frequency after it has been subjected to load fluctuations. The control areas considered for this paper comprise a reheat turbine and gas unit in addition to the thermal generating unit. Considering the practical scenario of operation, an appropriate generation rate constraint (GRC) has been included for each unit. The gain parameters of the 2DOF Tilted-Integral-Derivative Controller have been optimized by Arithmetic Optimization Algorithm (AOA). Later, the supremacy of the suggested algorithm is verified among the other well-known meta-heuristic approaches such as particle swarm optimization (PSO), Teaching learning-based optimization (TLBO), and Artificial bee colony (ABC) by evaluating under the same test conditions. The dynamic response of the proposed controller to load disturbances has been compared with prevalent controller schemes to bring about the efficacy of the prospective work.KeywordsLoad–frequency controlArithmetic optimization algorithmDeregulated power system2DOF-TIDN controller
