چکیده
This paper presents a practical model for load frequency control (LFC) of two-area interconnected power system. The proposed model is a non-linear power system and is framed with thermal generating units including security constraint governor dead band imposed by the governor. A Proportional Integral Derivative (PID) controller is used for the design and analysis of the proposed model. The Particle swarm optimization (PSO) algorithm is developed to obtain suitable control parameters to achieve the optimum performance. A unique objective function is also formulated considering the transient specifications. The closed loop performance is examined in the presence of constraint scenario and the results and characteristics show that the developed algorithm gives better performances. Keywords—load frequency control; two area power system; governor dead band; PID controller; particle swarm optimization
