PID controller Tuning Methods for Load Frequency Control (LFC)

Prof. Webby Mwaku, Mr. George Mugala, Gabriel Musonda

Abstract :

 The power system in Zambia relies on the southern Africa regional power system control center based in South Africa for load frequency control (LFC) [1]. If the tie–line connection or communication to the control center fails, cascading failure occurs because the power system cannot compensate frequency deviation by its self [2]. This paper presents ief study of automatic PID controller tuning methods that can be utilized to implement Load Frequency Control for the power system in Zambia.  LFC in the power system minimizes Area Control Error (ACE) to zero. ACE is the integral sum of power system frequency deviation and tie–line power flow error. ACE minimization using a PID controller can utilize any of the following algorithms or search criteria; Absolute Magnitude of the Error (IAE), Integral of Time multiplied by Absolute Error (ITAE), Integral of the Square of the Error (ISE), and Mean of the Square of the Error (MSE). However, the Integral Square Error (ISE) algorithm is re–Known for producing excellent results in various experimental works. Therefore, ISE and Particle Swarm Optimization (PSO) are investigated to determine suitable load frequency control for the power system in Zambia.
