Frequency Regulation in Two Area System with PSO Driven PID Technique

Namburi Nireekshana, R. Rama Chandran, G. V. Narayana


Now a modern days power system structures gives a major advantages in applications at the time, losses are also produced. To get the stable operation of this structured power system need balancing between total generation with total load demand and system losses. Rising and falling load demand throws off the real and reactive power balances. As a result, the system frequency and tie line interchange power deviate from their pre-programmed values. A significant change in system frequency can result in system failure.. In that scenario load frequency control optimization techniques is used Multiple Connect Area System to provide reliable and quality operation on frequency, tie line power flow.The Load Frequency Control (LFC) problem of an interconnected power system is solved using a recently proposed optimization method known as particle swarm optimization (PSO). In each section of the system, a standard Proportional Integral Derivative (PID) controller is employed for control. The PSO method of optimization is used to calculate the controllers' optimum gain values KP, KI, and KD.
