Ant colony optimization technique tuned controller for frequency regulation of single area nuclear power generating system

摘要

Obtaining energy from the power generating unit is a more critical issue in recent days due to the sudden increasing load demand than that of the past. In this proposed work the Load Frequency Control (LFC) of nuclear power system is studied by implementing the Proportional Integral Derivative (PID) controller as a secondary controller. The controller gain values are optimized by utilizing Ant Colony Optimization Technique (ACOT) by considering three different cost functions (Integral Absolute Error (IAE), Integral Time Absolute Error (ITAE) and Integral Square Error (ISE). Also, the effect of different energy storage units Hydrogen Aqua Electrolyzer (HAE), Superconducting Magnetic Energy Storage (SMES), Redox Flow Battery (RFB) is also verified by considering one percent step load disturbance in the investigated system. Finally, the simulation result obviously shows that ITAE cost function gives better result in terms of minimal domain specification parameters with good stability. Also, SMES improves the performance of system over HAE and RFB energy storage unit. (C) 2019 Elsevier B.V. All rights reserved.
